  3. Want a long range HD FPV machine with a GPS module for emergency RTH ?. Have a look to the new Skystars G370L HD: https://www.banggood.com/Skystars-G370L-HD-F4-OSD-FPV-Racing-Drone-PNP-BNF-w-RunCam-Split-2S-1080P-Camera-Mini-M8N-GPS-p-1455775.html In the menu, we have an old fashion H frame in 300mm format with 4mm arms but all electronics are updated: a F4 + betaOSD + a barometer, super strong individual 50A up to 6S BLHeli32/Dshot 1200 ESC, 2306/1600Kv motors associated with 7″ props!!!!. I can’t imagine in 6S!!! You will need a super super strong battery to avoid massive battery brownout. The VTX can output up to 800mW !!! with 40CH. No clear indication, if the VTX can be controled via the OSD… It mentions a voice control…. At least via PWM, the VTX can be controlled. The Runcam split mini 2 is here to broadcast both the FPV video in PAL/NTSC and to record HD videos up to 1080p@60 fps… Last element, the presence of a mini GPS module, very usefull for long range FPV flight in case of lost signal. Pre-program a RTH with a nominal altitude… and you are saved. For the receiver part, we have either a FrSky XM+ (medium range) or the FrSky R9 MM but this latter you will need a compatible transmitter module. I can guess this machine in 6S can probably reach top speed about 200 Km/h… a real beast. Wait & See. View the full article

  5. Dislike the term “HD” could mean, this is not a new 75 HD cinewhoop machine but “only” a new classic 75mm tinywhoop FPV machine, a new direct compatitor of the Eachine Trashcan. Here is the Supra 7: https://www.banggood.com/–p-1452202.html In the menu…. the same durable 75mm chassis of the trashcan with the dual-branch system reforcing considerably the extreminity of each duct’arms. For the electronic, some 15A !!! 4-in-1 ESC board… so no risk to cook mosfet even in 3S. Associated with, some 0803/16000Kv strong motors. The fight controller is F4 based with of course a Betaflight OSD builtin chip. The 40CH VTX offers an output power up to 200mW but no VTX control via OSD (no smartaudio or tramp support)… The main promoted feature is the presence of the caddx EOS 1200TVL. Be aware with such advertizing… first at the end only a pure NTSC/PAL signal will be transmitted whatever before the camera got higher resolution. If higher resolution mean probably better interpolation, it means also more sensitivity to the noise and more latency… so no free lunch…. Even with the presence of a WDR feature, in low light conditions this camera can be very noisy. Whatever, the machine is announced with the support of the main 3 receivers of the market and can be found also in PNP. With a weight of 35g without battery and 55g in 2S setup… the main advantage of this Supra 7 Pro over the Trashcan is the direct 3S support. Wait & See.

  6. Want a 2S 65mm brushless tinywhoop with the new 0802 motors ? Here is the new HBRC HBX64 for you: https://www.banggood.com/HBX64-1-2S-64mm-Micro-Whoop-RC-FPV-Racing-Drone-F3-OSD-S0802-Motor-25-200mW-800TVL-p-1449239.html Ok ok…. the electronic elements are old now….: a basic F3 board with at least a builtin betaflight OSD, an external serial based receiver (FrSky D8 w/ RSSI, FlySky AFHDS-2A and Spectrum DSM2/X). For the ESC… a 4-in-1 solution up to 10A, so no problem to handle 2S voltage. They are also Dshot 600 compatible. In the other hand, no control via the OSD for the VTX …. This latter got 48 channels and is able to output up to 200mW. The FPV camera is a basic CMOS 800TVL model… Of course no HD recording coming with….. but !!!! this machine weights only 24.5g (probably 26g with the receiver installed). The HBX64 is annouced to not exceed 40g (in 1S i guess) so should be around 47-50g in 2S setup. So nothing extraordinary but it’s small and powerfull in 2S so compatible for both indoors and outdoors applications HBX64 1-2S 64mm Micro Whoop RC FPV Racing Drone F3 OSD S0802 Motor 25-200mW 800TVL Specification: Item name: HBX64 1-2S micro whoop FPV racing drone Wheelbase: 64mm Weight: about 24.5g (without battery) Rec.flight weight: <40g (with battery) Flight time: 3-6mins (2S 250-450mAh) Flight controller: 1-2S F3, built-in OSD & smartaudio, OMBS firmware ESC: 1-2S 10A BLHeli_S Dshot600 Motor: 1-2S S0802 16000KV Propeller: 31mm 4-balde VTX: 0/25/100/200 48CH Camera: 800TVL FOV 150° Receiver: PNP without receiver/ BNF FS-RX2A/ BNF DSMX Pro/ BNF FrSky D8 receiver (option) Package included: 1x HBX64 1-2S micro whoop FPV racing drone PNP/BNF View the full article

  9. Welcome to RC Drone Forum
  10. Here's a good read on this: http://www.droneguru.net/license-to-fly-a-drone/ Flying a Drone Recreationally The Federal Aviation Administration (FAA) has provided clear guidelines regarding pilot license requirements for flying drones recreationally. If you fly your drone indoors, you don’t need a remote pilot’s license and you may not even need to register your drone with the FAA. If you fly your drone outdoors for recreational purposes then you will need to register the device if it weighs more than 0.55 pounds. At this point you have two options for flying your drone recreationally. According to the FAA, you do NOT need to obtain a remote pilot license under the following conditions: You are flying the drone purely as a hobby and for solely recreational reasons. You follow the guidelines set forth by your local community. You keep your drone within a visual line-of-sight. Yield to any and all manned aircraft. Remain at least five miles away from airports and air traffic control towers. Your drone must not weigh more than 55 pounds. You can also fly your drone for recreational purposes if you or someone monitoring you has a valid remote pilot license. The restrictions for such recreational flights are as follows, according to the FAA website: You must register your aircraft as a non-model, unmanned aerial vehicle. You must adhere to the FAA’s Small UAS Rule, Part 107. It is an absolute requirement that if you operate your drone under this second set of rules that either you or someone supervising you has a valid remote pilot’s license. Long story short, if you plan to fly your drone in a field, park, or other area where there manned aircraft aren’t constantly passing through and there is no immediate threat to power lines or people then you do not need a remote pilot’s license, although you will likely need to register your drone and ensure that you are only using the device as a hobby.
  11. Best budget drone in 2019 - best under $300 drone 2019 Lots of drones have been introduced into the marketplace in the last 3 years. Majority are just basic, and just few top class drones with super features are available. But then you need to know what's best for your investment. If you want the best, go for something inbetween cost, and yet of top standard. That's why drones that fall within the $200 - $300 range delights drone pilots, because of affordability and delivery. Currently in 2019, I found the Altair Outlaw drone selling at $279 the best under $300 drone with super features. FLY WITHOUT FEAR In addition to its durable plastic design and extra included parts, the Outlaw features built in controls to ensure that you don't lose your drone. Built-In Features: One-Touch Return Low Power Return Lost Contact Automatic Return Return to Home Function (RTH Procedure) In plain English: the drone will prevent itself from crashing under certain circumstances and even fly back to you if you've lost contact. Watch this video about this outlaw drone and all its features below: All the best flying the best... Sent from my TECNO F3 using Tapatalk
  12. INTRODUCTION Better late than Never…. Here is my review of the Hubsan Zino. This is a foldage 3-axis stabilized 4K@30 video plateform. The FPV link is done with a specialized 5.8G connexion. Main caracteristic are solid: about 700g, 23 min of flight time and about 1km of control range. No obstacle avoidance sensors or VPU unit. The main positive point is its price!!! less than the half of a DJI mavic. Of course many many brands try to “wannabe” DJI … Almost all failed. This review comes after 3 months of the introduction of the Zino. First reviews shown a very bad GPS altitude hold performances, some toiled bowling effect and even some fly aways… We will see if with the new batch machine I received, flashed with last firmwares, the situation is improved. Here is my first elements of my review. BOX CONTENT + 1 x Hubsan Zino + 1 x Transmitter + 3 x USB charging cable + 4 x Spare props (2 CW, 2 CCW) + 1 x Power unit + 1 x Charger (15V, 1A) + 1 x Screwdriver + 1 x Instruction manual (English) Three USB cables are provided. One for iOS, one with USB-c and the last with a microUSB. Seems they are specialized cable and not simple OTG. 10cm only…. They are too short if you plan to use a tablet with a DIY holder. Important, you can replace this cable with a simple microUSB to microUSB cable. You will need a cable extender plugged from one of these three cables. OVERVIEW -FRONT VIEW Unfolded, we have a 350mm machine. Everything is fully plastic based for the structure. The general quality of the plastic is average more hard than flexible. We could expect more quality for the plastic. A plastic dome covers and protects pretty well the 3-axis camera-gimbal system I received the last batch model since the camera house got now a square shape instead of a circular one. -SIDE VIEW The left side shows respectively from left to right: a led light showing the camera activity, a microUSB port to flash a new camera firmware and the microSD card slot. Prefer a fast U3 card, for example a 32GB formated in FAT32. If you plan to use a larger model, you will need a specific software to format the card. -REAR VIEW -UPPER VIEW A unique power button. Press and hold 5s this button to turn on or off the Zino. When turned on, the Hubsan delivers a very treeble sound almost unaudible. -BOTTOM VIEW -WEIGHT 710g with the battery. Motors and props Battery A 3000mAh 3S LiHV battery with a specialized connector. No specific led status to visualize for example the amount of remaining of charge. It’s not a big deal, but the more important is more the presence/absense of a autostorage buitin circuit when the battery is parked for several day With the original charger, it takes more than 2.5h to fully charge the battery. It’s super long …. The leds are solid red when charging and becomes solid green when it’s done. It’s strongly advise to build a DIY 3S balancer plug with a lead power connector. Here is mine. It can be used to fine balancing all of the three cells. Important, when I used my own cable, I noticed that the cells 2 under load presented a voltage drop of -0.2V versus cells 1 and 3. I don’t know if it’s linked with the builtin electronic board biasing the voltage reading. Camera module The gimbal system is dampened but the immediate feeling with this gimbal is its fragility…. Be sure from a medium shock on the system, the gimbal will break. The sensor offers to record video in 4K up to 30fps. Same for the 2.7K resolution. From 1080p, faster fps are offered (60fps). With the original camera firmware, the datarate is around 40Mbit/s. Transmitter The transmitter is a Mavic inspired model with the possibility to attach directly a smartphone but not a tablet out of the box. Everything is white…. even the buttons. It’s super hard to guess the logo printed on them especially with strong lights. So in practice, you will have to loose 3-4s to guess the role of each buttons.. There are small also. The general plastic quality is not good. It’s more a toyquadcopter transmitter than a >350USD one. Even worse, the sticks are fully plastic. No possibility to install some metal models. Springs are weak… Controls are imprecize. For example, it’s hard to keep a full straight one …. I don’t like the transmitter. Unfortunatly, it’s a new protocol developped by Hubsan. No possibility to control the craft with a DeviationTX compatible radio. The pitch of the camera can be control via this left dial. Until last firmware, this control was very touchy. It’s solved with last updates where now you can tune the rate by yourself. The specific microUSB port used to charge the builtin battery and to connect the transmitter to your smartphone A 5 pin port. This one is important if you want to flash a new RC firmware. Unfortunatly, you will need to short the two left pins. One safe solution is to use a 1.5mm JST 2positions cable. A maximum of a 6.3″ can be installed. If you plan to install a tablet, unfortunatly the dimensions of the transmitter are incompatible with all Mavic tablet holder available. You will need to mod yours. Here is my mod but better solution can be obtained without problem As said proviously, you need to use the original cable with a cable extender. No possibility to install directly a 20cm OTG cable for example. It’s not working. UNBOXING, ANALYSIS AND TESTING The first video is the unboxing and the introduction of the “X-hubsan” appz. This latter unify all WiFi based Hubsan product. It’s a very good application in general. For example, the waypoints definition for mission planning is simple. The orbit mode also offers a lot of options. It’s great. As the Hubsan Zino is known to have poor GPS hold stability, be sure before each take-off to perfom locally a compass calibration. A minimum of 9 satellites is required to take off (You can fly without GPS assistance, but you have to turn off the corresponding option in the settings). This second video shows the general performances of the machine in term of GPS hold, video stabilization and advanced flight modes. If I can confirm that the GPS hold is not beyong the best, it’s not also catastrophic, at least with moderate wind conditions. The z-elevation deviation is about 1.5m and is more severe when the machine is below 3m high. The x-y deviations are about 1m. For the video stabilization, the performances are great….. No real complain/vibration can observed. That’s the most positive point. With the original video firmware, if the color rendition is good, the video is not super sharp especially for the background scene. Trees and branches are blurred for example whatever the resolution. In term of FPV distance, with the original firmware, seems there is a 1Km geofence barrier. For the advanced flight modes, the visual tracking model is just working great…. I liked the fact that if he lost the track, he offers to you a target re-association solution. The orbit mode works perfectly also.. One can regret the lack of specialized selfie flight modes “à la DJI”. The flight duration was reported in practice between 22-23 min. If you are using the original charger, it’s advised after a first charge, to restart the charging procedure after a couple of minutes. Some extra mAh can be stored in this way. With last firmwares, a new video setting is available where the datarate is increased correspondly With these last updates, when the sharpness is set to maximum, the general quality is improved… I even found the gimbal stabilization also improved. In another hand, no real improvement for the GPS hold stabilization. It’s not a drama but it will be for example hard to have a stable selfie video in low altitude, i.e. the machine will move constantly. Another introduction is the possibility to monitor the SNR of each available 5.8G WiFi channels and select the less noisy. Of course in order to maximize the video link. I was also able to go beyound 1 km. I am pretty sure some with some windsurfer installed on both antennas, we can go further. CONCLUSIONS Clearly the Hubsan Zino suffered of some imature firmwares linked with a too early introduction. Probably hubsan knew than Xiaomi will delivered soon the X8 SE. In fact the Zino is blocked between the Xiami A3 and the X8 SE. If you are looking for a brainless RTF machine ultra stable and durable, probably go for the Xiaomi A3. Anyway, if you want more advanced flight modes, a better gimbal stabilization and camera, finally flashed with all last firmwares, the Zino is a good machine and can be recommanded. It’s not an amazing plateform but a good one. Orbit mode, waypoint planner and visual tracking are really efficient. The flight duration of 23min checked in practice is good enough. But be sure with the Zino that you will need to perform each time a solid compass calibration before each take off. Actually thanks to the code f7c8f3, the Hubsan Zino can be found around 238 euros… so more or less the same price as the Xiaomo A3. PROS + Great Gimbal video stabilization + 23 min of flight time + Foldable + 710g + Good iOS/Android appz + Good visual tracking + 4K@30 resolution + Nice videos (improved with last firmwares) + Relatively cheap CONS – Not ultra precize GPS-hold (improved with last firmwares) – Potential toilet bowling effect (improved with last firmwares) – Some reported fly away (mostly with first firmware releases) – Loose 4-5m of altitude after a fast u-turn (fixed with the last firware 1.1.48 update) – Poor plastic quality for the transmitter – No color printed TX buttons/hard to guess with strong day lights – Imprecize transmitter controls/sticks – Need to turn on developper/USB debugging for android connexion – 1Km max distance hard-coded into the Zino’firmware (fixed with the last firware 1.1.48 update) – High compression/blurred background details (new “sharpness” option available with last firmware increase the datarate) – Props occlusion from mid-forward speed or fast turns – Need sometimes multiple USB plugging/unplugging to retrieve the video feedback – Need an extra 1.5mm JST XH plug for the TX’firmware update procedure – Long battery charging (>2.5h)=>Need to special 3S balancer plug for professional LIHV charger usage – Short USB cables (10cm only). Impossible to plug directly with them a tablet – Real 4K sensor? optional – No obstacle avoidance sensor This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thank them for this attitude.

  13. Hello! Brand new to the forums here and excited to educate myself on drone usage, certification, and flight. Long time surface RC enthusiast that's making the leap to air.
  14. Hello - Long time surface RC enthusiast here, but total newb to RC flight / drones. I've been mulling purchasing a drone for a couple years now, and I think it's finally time to take the leap. My intention is to use the drone primarily in a recreational manner, but I've also been doing some research on commercial applications such as Real Estate marketing. It looks like my first step should be to find or enroll in a local or online course to obtain my remote pilot certification, Part 101 and Part 107? I have a lot of questions and was looking to get feedback from folks here about the best way to proceed. Should I purchase the drone and get some flight time first? Is it even legal to fly a drone prior to certification? (There seems to be some blurry areas here) Should I dive right in and do the course and get certified first? Recommendations on a drone that is "forgiving" to learn on, but will allow me some good overhead as I advance and gain skills? Ok, thanks in advance for any feedback and recommendations. I appreciate the help! ~Mike
  15. Well …. yet another SPCMaker product/attempt to release a jellofree HD machine. Here is the Miniwhale 78 HD: https://www.banggood.com/SPC-Maker-Mini-Whale-HD-78mm-Micro-F4-FPV-Racing-Drone-PNP-BNF-w-25100mW-VTX-Runcam-Split-Mini-2-p-1439455.html We have an hybride tinywhoop brushless FPV racer with a main 1.5mm carbon frame coupled with a full nylon/whoop structure. In term of electronic, we find the same as for the K’serie, a i.e. F4 micro FC, a 4-in-1 12A ESC board 3S compatible (and prabably 4S). For motors, 1103/10000Kv coupled with 1635 GF props. For the HD part …. still the Runcam split Mini 2… I really hope the fixed version (I think so)… and as you already know with SPCMaker, they can deliver great machines as some rubbish ones since there is almost no real tunings from their side. According to the structure, I do think this machine is finally the Jellofree HD machine from SPCMaker… Annouced to be 52g without battery, probably 54g with one of the three receiver modules proposed (FrSky D16, Flyskk AFHDS-2A and Spektrum DSM2/X). Specifciation: Brand Name: Spc Maker Model: Mini Whale Item Name: 78mm Whoop FPV Racing Drone Version: PNP ( Without Receiver) / Compatible Flysky RX/ Compatible Frsky RX Compatible DSM2/DSMX RX / Compatible Futaba Receiver ( Optional) Wheelbase: 78mm Weight: 52g ( Without Battery) Flight Controller: MICRO F4 Flight Controller ESC: MICRO 12A 2-3S Blheli_S 4 In 1 ESC Motor: 1103 10000KV Brushless Motor Propeller: Gemfan 1635 40mm 4-Blade Propeller FPV Transmitter: 5.8G 40CH 25/100MW VTX Receiver: Without Receiver/ Compatible Flysky RX/ Compatible Frsky RX Compatible DSM2/DSMX RX / Compatible Futaba Receiver ( Optional) FPV Camera: Runcam Split Mini 2 1000TVL 2.1mm Lens P/N Camera Battery: NOT Include Package Included: 1 x Mini whale Kit 4 x 1103 kv10000 Motor 1 x MICRO F4 Flight control 1 x MICRO 12A 4IN1 ESC 2 x GEMFAN 1635-4 40mm CW 2 x GEMFAN 1635-4 40mm CCW 1 x Runcam Split Mini 2 Camera 1 x 5.8G 40CH VTX 1 x 12mm*20mm Battery Strap 1 x DSMX/Frsky/Flysky/futaba(optional) View the full article
  16. Yes another Tinywhoop HD/Cinewhoop HD, this time in 80mm format … with the Gofly Scorpion 80 HD: https://www.banggood.com/Gofly-RC-Scorpion-80HD-80mm-Micro-Brushless-2S-Whoop-FPV-Racing-Drone-F405-RunCam-Split-Mini-2-Cam-25100mW-VTX-p-1438742.html Not a lot of informations available, but from the photos, it seems the HD recording is done via the fixed version of the Runcam Split Mini 2 with the lens in M12 format (instead of M8). The full plastic struture looks robust. The Scorpion is 3S compatible thanks to its strong 12A BLheli_S ESC coupled with 1103/11000KV motors. The 40CH 5.8G is Smart Audio compatible. You will be able to control the output power from 25mW up to 100mW. The machine is proposed in PNP or in three BNF options (FrSky D16/Flysky AFHDS-2A/Spektrum DSM2,X). With a weight of 55g witout battery (probably 57g with the receiver), this machine is 10g more heavy than the Modula 7 HD but lighter than the Tinyleader HD. Wait & See … Specification: Brand name: GOFLY-RC Item: Scorpion 80HD 2S Brushless Whoop Micro drone Wheel base: 80mm Weight: 55g (without battery) Size:113x103x41mm Power input: 2S-3S lipo battery Motor:1103 11000KV brushless motor/1.5mm shaft ESC: 4in1 BLheli_S 12A Flight controller: F4(F405) OSD/Smart Audio ready Camera: RunCam Split Mini 2 1080P Video transmitter: 5.8G/25-100mW/40CH/SmartAudio Ready Receiver: without receiver/ DSMX/ FS-RX2A/ XM+ receiver(optional) Propller: Gemfan1636 40mm 4-blade Package Included: 1x Scorpion80 HD Micor Drone 1x battery mount 1x battery strap View the full article
  17. The only simulator I can find for Mac is Aerofly RC7. No response from the company to questions posted from their site. Does anyone have experience with this sim? Can I control it using the Phantom 2 RC transmitter? I also have an OrangeRX FrSky USB dongle 6ch receiver.
  18. As you already probably know, the new fashion in the micro-drones market are Cinewhoop machines, i.e. a 65-85mm prop-guarded/whooped FPV brushless quadcopter with a HD-FPV combo camera able to broadcast your favorite FPV link with low latency while recording in HD format the flight session and of course the most jellofree as possible. Here is a new competitor with the iFlight CineBee 75HD: https://www.banggood.com/IFlight-CineBee-75HD-2S-Whoop-RC-FPV-Racing-Drone-W-SucceX-mirco-F4-12A-200mW-Turtle-V2-HD-PNP-BNF-p-1433255.html Dislike most of last Tinyhood HD (Modula 7HD, TinyLeader HD, BetaFPV, etc…), here most of the structure is carbon based with an H design to be prop occlusion free. What I like also in the design, the microSD port looks easy to access. What about the access to start/stop record button ? no information yet. In the feature, it’s mentioned that the cam can be controlled as well by the OSD… It’s surprizing since as far I know until now, the Caddx turtle V2 product is not supported by Betaflight to control the triggering via a switch. So maybe they did it and if it’s true, it’s a fantastic news. For the HD-FPV part, we have the Caddx Turtle V2 model known to be first relatively insisible to vibrations (thanks to its M12 lens). The Cinebee uses some 12A BLheliS ESC coupled with strong 1103 motors (much stronger than 0802 motors as in the Modula7 HD). The price is a weight estimated about 64.4g without battery (so around 18g more heavier than the Modula 7 HD). With a 450mah 2S LiPo, the machine will turn around 85-90g… No doubt this machine is also 3S compatible. But with 40mm props… in 2S, the machine should be already powerfull enought Don’t forget this type of machines are not really some acro-trainer ones but more low-riding cruizers to offer stable and jellofree HD video footages. For the FPV part, the VTX can output up to 200mW should be enought for 500-600m of FPV link. The Cinebee 75HD is proposed in PNP or in three BNF versions ( FlySky ADHDS-2A, FrSky D16 and DSM2/X). My priors are relatively good on this machine…. I will try to grab one for review… I am not sure I will, but good news, I will review the final version of the Modula 7 HD. Wait & See….

  19. Remember my last Diatone GT 249+HD test with the builton RunCam Split Mini 2? A full 95mm jelly machine mainly due to the defective M8 Lens of the RCSM2. To fix that you need the new M12 model so a wider lens potentially no more compatible with the frame. To overcome this problem, Diatone decided to deliver the machine with a Caddx Turtle 2 instead: https://www.banggood.com/Diatone-2019-GT-R249-HD-MK2-Edition-2-Inch-95mm-F4-OSD-FPV-Racing-Drone-PNP-w-TX200-VTX-Caddx-Turtle-V2-HD-Camera-p-1427231.html First of all the camera is in M12 format… and reduce drastically the amount of jello. For the other ingradients, they are the same: a good F4 flight controller with a builtin OSD, strong 25A 4S compatible 4-in-1 ESC board and 1105/5500Kv motors. For the VTX, we have a IRC tramp compatible model able to switch between 25mw up to 200mW…. So probably at the end the first 2″ FPV HD machine without jello. The new diatone exists also in 2.5″/115mm variant. Of course, I am like saint thomas…. I will believe in it if and only if I can confirm by myself that fact. Wait & see as usual… Diatone 2019 GT R249 HD MK2 Edition 2 Inch 95mm F4 OSD FPV Racing Drone w/ TX200 VTX Caddx Turtle V2 HD Camera Specification: Brand Name: Diatone Model: 2019 GT R249 HD Item Name: 95mm F4 OSD FPV Racing Drone Version: PNP ( Without Receiver, battery and radio transmitter) Drone Wheelbase: 95mm Recommend Lipo: 3-4S ( Not Included) Weight: 85g ( without battery) FC: Mamba F405mini/MPU6000 ;OSD;16M Flash;BEC Camera: CADDX Turtle V2 VTX: RunCam TX200 25/200mW ESC: Mamba F25 /25A 4S ESC Dshot 600 Motor: Mamba Racing MB1105 5500KV Package included: 1 x Diatone GTR249 2 Inch RC Drone View the full article
  20. INTRODUCTION After the super popular Xiaomi FIMI 4K, here is the Xiaomi FIMI A3, probably the cheapest 1080p stabilized video plateform in the market. Dislike its big brother, we have no more a WiFi based digital hi-res FPV system but an old-fashion efficient analog system in order to save costs. But the main advantage of this machine is probably to offer a real 2-axis mechanical video stabilization overlayed with an Electronic one for the third yaw axis. The machine comes in RTF edition where the radio command integrates also a FPV monitor and a builtin DVR to record your favorite flight/FPV sessions. Everything for around 250USD…. so clearly in the same price segment of the Hubsan H501S or the MJX Bugs 3/6. Xiaomi FIMI is known to offer good quality for their quadcopters, let’s check if this entry model will still continue this traduction. BOX CONTENT Like any Xiaomi model, the box is optmized in size to reduce post shipping fees. The box is suprizingly small …. but every thing is here inside + 1 x Xiaomi Fimi A3 + 1 x Transmitter (with a builtin 1S LiPo battery) + 1 x Charger + 1 x Power unit + 1 x 3S balancer plug cable + 1 x USB to microUSB cable + 2 x Spare props (1 CW, 1 CCW) + 1 x Instruction manual (English) First small deception…. we have a very basic LiPo charger… like the ones included with basic toysquadcopter. It uses the 3S JST balancer plug connexions. Two LED lights are present: one when the charger is powered and another when to show charging activity. We will talk about this charger later… Second negative point is the absence of a camera dome casing protecting the gimbal…. Of course you can design easily one but…. out of the box, it’s really missing…. OVERVIEW The machine is built with the same quality plastic of the Xiaomi 4K, a soft and flexible one with high quality. The design is relatively flat, a 323mm machine in term of dimension. Unfortunatly…. arms can’t be folded so it will require more space for transportation. Probably one of the most negative point. -FRONT VIEW No obstacle avoidance sensor…. Was predictable with such low-entry model. The gimbal is a micro compact one where the integration of the camera is included in the tilt axis. Stabilize a super lightweight camera module is really challenging. In general only DJI managed this job with the Spark & the mavic. -SIDE VIEW No visible USB/microUSB port anywhere. The design is very wind profiled with curvy shapes. Each arms ends with some lights. Rear ones indicates more the battery status. As usual, when red lights start to flash fast, it means the battery becomes low. -REAR VIEW Battery connector with redondant pins for a 3S system Hidden and protected by the battery, the microSD port and the microUSB to update both the flight controller and camera firmwares No risk to loose the microSD card during a crash. Smart location. -UPPER VIEW A small GPS/glonass dome…. -BOTTOM VIEW The power button is located button. As the former model, to turn on/off the machine you will have first to short press on this button, release it then long press and hold it diring 3s. Notice the absence of any VPU system to increase potentially even better the altitude stabilization… especially indoors where the GPS signal is absent. In this situation, it mean the stabilization is done only via the builtin barometer One really positive element is the presence of a DIY port when you can plug some future third party accesories. They are controlled via PWM connexion. The rear right button is dedicaced to trigger this port…. Great -WEIGHT Just a little bit less than 560g ….. not so so bad for a 350mm video plateform. Motors and props Some 1805 motors branded by FIMI directly directly. Notice that CCW motors are painted with an orange line in order to match the corresponding prop directly 3mm shaft section but with a spring installed for the new prop lock system The prop installation takes just a fraction of second…. It’s a brilliant solution !!!! I really like it… Very smart. Just push the prop, turn a quater of tour and you are ready to flight !!!! Battery Of course we have a proprietary battery, a 2000mAh 3S model…. but not smart…. I mean there is no specific auto-storage capacity. So if you plan to park this machine for a couple of weeks, you will have to discharge by yourself each cell at 50%. By reading carrefully the sticker, we can read 12.75V…. so clearly is not a simple LiPo with a max of 4.2V per cell but a model more close to a LiHV battery up to 4.35V per cell. The problem is the actual charger can’t reach 4.35V per cell …. Si in practice you won’t charge the battery at full capacity. One way to overcome the non-possibility to fully charge the battery is first of course to use a charger with LiHV capacity but you will need also the cable compatible with. For this, you can mod the provided one by soldering a mean lead connector. As soon as the cable is built, it’s interesting to notice that each cell don’t have the same internal impedance. In fact the cell 3 shows a higher value, linked with a builtin resistance in the circuit. In practice, as soon as you start the charge cycle, the cells 3 show +0.1V more versus cells 1 & 2. Camera module With a FOV of 80 degrees, the camera sensor is a 1/3.2″ CMOS model. The camera is fully integrated with the tilt axis to gain weight and place. On the pitch angle can be controlled by the left rear button micro Dampening balls installed The video recording is splitted into 1Gb files of 2min24. In 1080p@30fps, the datarate is about 60Mbit/s…. Not so bad at all. Here is a raw sample of the A3 If the video is not super sharp, I don’t suffer too much of blurred edges as reported from some earlier users. In any case, with default settings, the white and the blue color are oversaturated. Luckely, a bunch of settings are available via the radio. The sound is not recorded. Transmitter One of the most positive element of the bundle, i.e. the radio transmitter including both a 2.4G radio link to control the machine and a 5.8G builtin VRX collecting the CVBS video flux transmitted by the quad. The quality of the transmitter is really good with nice and precise metal sticks. Internally the antennas are attached to the main PCB/modules via iPX connectors. So it can be super easy to replace default antennas for some higher gain ones. Via the radio settings, it’s possible to change the 5.8G frequency. It means that this channel is transmitted in the radio protocol. If the quality build is really good, the screen got a brillant surface and in presence of strong daylights, it’s hard to see all details. Clearly, the radio would deserve to have a sunshade installed or in the worst case a system to welcome one. It’s not the case …. In the right part, this tiny joystick allows you to enter into the main radio/quad/camera settings or to access directly for smart flight/DVR functions. A microUSB port is here to charge the builtin battery, to update the RC firmware. Nearby a microSD slot to record your FPV sessions. As any GPS based machine, the compass calibration is a must to do procedure. Two clock-wise mouvements are required. They are clearly depicted by the animation in the radio. When you boot the radio, you have centralization of all pre-flight informations. The FPV signal is recorded in D1 NTSC format in 720×480@30fps. Here is a raw sample recorded via the builtin DVR. It’s more dark than the direct signal which can be recorded by an external goggles/FPV screen. Probably linked with the extra OSD informations overlayed. As for the HD recordings, the FPV recording is splitted into 3min files. The sound is recorded and as you can see, the GPS informations are stored. A pretty nice option to localize your machine if you loose it during a long range flight. A small artefact can be noticed with the DVR files. You can often observed at end of each file, a ghost video fragment of a former recording. It happens even if you format the card….. Need probably a full in depth formating. UNBOXING, ANALYSIS AND DEMO FLIGHT Even if my FIMI A3 comes from a second batch and with almost up to date firmwares, I decided to install all the new firmwares available at: https://www.fimi.com/. Firmwares update procedure works flawless. With the new firmware, a new “cinematic” flight mode where all rates are limited as well as the gimbal one. I guess also, EIS is also applied over the two-mechanically stabilized axis. This new mode is ideal to shoot super smooth videos. This first video shows the content of the bundle, the role of each radio-transmitters buttons and probably first important mod to do, the DIY charger cable from the one provided in the bundle. Important point, if you plan to flight far, you will have to extend the max flight distance setting. Notice also if you plan to fly this machine in europe, you must in theory turns the machine into CE mode instead of FCC (default setting). When associated with a charger with a LiHV program, as you can see, the voltage of the cell 3 is about +0.1v higher than the two other cells. At then end of the balance program, each cells will converge to 4.35V. After a local compass calibration, the machine in GPS mode is able to take off from 9 satellites. Push lower inner both stick to arm the machine. From 1m high, the altitude hold of the machine is really accurate !!!! Impressive. What I really like is the silence of the A3… Beyond 20m, you can’t event acoustically notice the quadcopter. Clearly the the video stabilization system is doing a great job. It’s almost without any vibrations….. really this is the most impressive point of this machine. In term of video quality, with the last camera firmware, the color rendition staturates a bit white and blue color. Thanks to all the camera setting available (especially EV), you can fix that. The video is good…. not ultra sharp (a bit blurred for background scene) but really not bad at all. Small details, when you land the machine, Recordings are automatically stoppped. To enjoy a full control and FPV range, you must install antennas vertically. Out of the box the machine can achieve 1km very easily. Important point: when the FPV signal is too low, the builtin remote FPV screen becomes blue. It’s really annoying. It may be fixed with a firmware update, not for the radio but for the LCD controller…. probably with a programmer stick. So not an easy procedure. Via pushing the small dial up, you can have a quick access to all the smart flight modes. When engaged, you can discard the selected flight mode by pressing the home button. The RTH works fine and had a precision about 2m from the take off location. The orbit mode can be controlled via the pitch & roll axis of the right stick. The rolls controls the velocity of the circling, the pitch the radius. No possibility to tune the yaw with the mode. The Cinematic mode smooth everything….. So fly slowly and the video results will be really good. The gimbal control is also slowed down with this mide. The fixed wing mode limit also the pitch & roll axis. Be aware, you have a lot of inertia associated with….. It’s hard to stop the machine quicly in this mode. The follow-me uses the second builtin GPS module integrated in the radio. In general such kind of follow-me are not super accurate but here it’s not the case…. It’s working well…. not as good as a visual tracking mode but it’s really efficient. For the DVR recording, as mentioned before, the end of each DVR files can present some ghost segments from previous recorded files. Don’t know if it can be fixed with a new RC firmware update. A full and slow format helps a lot of to reduce these artefacts. When I like, DVR saves also important informations like the GPS coordinates of the machine. A little disapointing element is the flight duration, about 20min even when the battery is charged in LIHV mode. A bit far from the 25min advertised. CONCLUSIONS The Xiaomi FIMI A3 is a good machine. When sold around 250USD, there is no real other competitors because this is the sole machine with a gimbal system while other offer in the best case only a EIS stabilization. It kills for example the (2 years old) Hubsan H501S or any last MJX Bug products. The FIMI A3 is stable, accurate, reliable without toilet bowling effect. The quality build is also very good. Of course there is no 1080p@60fps or 4K resolutions, but the 1080p@30 fps recordings are already not bad. We can maybe regret the non-possibility to fold the machine for an easier transportation. When balancing all positives points with the negatives, the FIMI A3 can be easily recommanded. PROS + Cheap stabilized video plateform + Almost perfect video stabilization + Good 1080p@30fps videos + Full RTF solution + Good quality build + Great FPV & control range + Easy prop installation + OSD informations (GPS coordinates) saved with the FPV link via the builtin DVR + A lot of advanced flight modes + 22min of flight duration ? => More about 20-21min + Silent machine + DIY port for 3th party accesories + Relatively cheap CONS – Not foldable – No gimbal dome for transportation – Need a DIY mod to charge fully the Li-HV battery – Need a charger with the Li-HV program – Cell 3 of the battery got higher internal resitance – Videos/photos not sharp => blurred on borders – Color rendition (too much blue and white) – No 1080p@60fps – Blue Screen when the FPV signal is lost/low – Brillant FPV screen=>Need a sunshade – Inportant OSD informations (GPS coordinates) are added by the RC not natively on the drone=>External VRX won’t be able to receive GPS informations. Only AVout export them but you will use the radio builtin VRX – Potential “Ghost video fragments” at the end of each FPV DVR files This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review.

  21. INTRODUCTION The SKYSTARS Ghostrider X95 (GR-X95) is a 95mm FPV racer with a full transparent plastic body diffusing cool light’s effects. The GR-X95 frame is a full monoblock pastic model with a builtin prop guard. For the electronic, we have a F4+betaflightOSD flight controller, some 20A/Dshot600 ready 4-in-1 ESC 4S compatible and for the motors some 1104/7500Kv. The FPV rig is composed of a 700TVL CMOS micro camera and a 48CH/200mW max 5.8G VTX. The control of the VTX can be done via the OSD thanks to the IRC tramp communication. The GR-X95 can be found in PNP or in BNF with either a FrSky D16 or a Flysky AFHDS-2A solution. There are already planty of such FPV racers in the market… Is this one bring something new/better ? Let’s have a look. BOX CONTENT + 1 x Skystars Ghostrider X95 + 4 x Spare props (2 CW, 2 CCW) + 1 x SBUS/Serial receiver cable + 1 x Bracelet + 1 x Set of stickers No instruction manual…. OVERVIEW The frame is pure X-design of 95mm The main central inner square is a boon of 3mm of thickness while each individual bar of the prop guard system is only 1.5mm. The material is a flexible transparent pastic. Flexible enough to be deformed and absorbe energy of most type of crashes. -FRONT VIEW The design is pretty cool full white transparent with a tall central dome jailing all the electronic tower and the FPV camera. Mine came in PNP version With a FrSky XM+ attached, I decided to drill two small holes on the top of canopy to install vertically both antennas. It reminds me the famous cartoon caractar Maestro from “once upon the human” Out of the box, the machine comes with the classic “prop in” configuration. I decided to use more the prop out system to have the lens “grass-free”. -SIDE VIEW The left side is the unique way to access to the microUSB port and the boot button of the F4 ominibus flight controller. You will need to use a USB cable with a very thin USB connector. Unfortunatly, via this hole, you can’t access to the unique VTX button located just above. You will need to disassemble the top cover if you want the access. It’s not a big deal since the VTX can be completly controled via the OSD. -REAR VIEW With the FrSky XM+ installed rear. -UPPER VIEW -BOTTOM VIEW A battery strap is preinstalled long enough even for a compact 4S battery. On the bottom, rubber anti-slicing band is installed to secure the battery installation Two of the four M2 hexscrews holding the tall dome. The associated screw’s threads are in plastic so be aware versus multiple opening or crash…. These threads will have some loose….. and you will need probably a new spare dome. -WEIGHT Almost 88g standalone …. clearly it’s not light…. and above 110g with a basic 3S 350mAh LiPo. Expect to be above 125g in 4S. Motors and props 1104/7500Kv….. they can handle without problem 4S….. but as you will see….you can already forget 4S applications. It’s strongly advised to secure each motor’s screws with a thread locker….. As you will see vibrations are really important and if you don’t want to loose mid-flight a motor…. gluing the four M2 hexscrews is really recommanded. Triblades 2040 chrystal clear prop are installed and four given as spare in the bundle. Camera module Assumed to be a 700TVL CMOS 1/3″ model with a sensitivity of 0.1Lux. Annonced to be a NTSC/PAL also but in practice it’s turned in PAL by default. The fied of view is about 115 degrees. The lens can be oriented from 0 degrees up to 60 degrees without canopy/prop occlusion. I didn’t find a switch to turn the camera into NTSC. Disassembling The top layer is a buzzer/led lights floor. Lights are completly configurable via Betaflight. A free UART6 3p port is available. Use the cable to connect your favorite receiver. A close up on the microUSB port and the boot button to update Betaflight. When the serial receiver is attached UNBOXING, ANALYSIS, CONFIGURATION AND DEMO FLIGHT Out of the box, the machine is well tuned in betaflight at least in term of receiver, flight modes, OSD and light controls. The F4 omnibus board is flashed with Betaflight 3.5.3 so a modern version. All PIDs and filter settings have been also optimized probably more for 2S setup. In term of flight modes, anti-gravity and air mode are enable by default for all flight modes. Even “flip over crashed” is enable via the AUX3. So just a little fine-tuning is required to match your own choices. A good start at least. The machine is strangely adveritized to be flew more in 2S while ESC & motors can support 4S… strange….. And effectively as soon as you start to plug a 3S LiPo, you understand: below 50% of throttle input this machine is noisy but fly ok. It’s not a monster of power at least for this rate. But when you push the throttle stick further, you can hear massive vibrations in the structure and of course it’s directly translated into huge vibrations in the FPV signal video. More the light sensitivity of the CMOS camera is pretty poor with for example the “black sun” effect. This camera is not sharp too… Really a disapointing model need to swapped for a better camera. These vibrations are really really annoying….. execpt if you plan to cruize slowly with, it’s killing the interest to this machine. I tried different PID & filter optimisations…. no real better results obtained. Clearly a disapointing situation. Flight time with a 350mah are also short, about 3min30s maximum….. At least in term of durability of the structure, I was positively impressed. I crashed the machine many times into soft groud, trees & branches…. No damage at all. I can’t promise same results over hard concrete. CONCLUSIONS The SKYSTARS Ghostrider X95 is finally a disapointing machine linked with the poor FPV camera and the huge vibrations as soon as we start to fly the machine a little bit in a sporty way…… If we can replace easily the camera for a better model, it’s another story for the vibrations. Probably a new frame is required…. Finally…. the interest of the GR-X95 is limited versus flawless competitors except if the light effects is a must to have for you. PROS + Cool light effect + Monoblock pastic durable frame + F4 board + IRC tramp compatible VTX CONS – Tons of vibation from 50% of throttle input – Poor FPV camera with poor light sensitivity – Need to open the machine to bind the receiver – Heavy Dump_BF_3_5_3 This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review.

  22. INTRODUCTION The Fullspeed TinyLeader HD is probably the first 75mm HD tinywhoop FPV racer. HD means here, thanks the Caddx Turtle 2, the possibility to record video footages in 1080p@60 resolution while broadcasting the FPV signal with low latency to be FPV racing compatible. This machine got a F4 based flight controller with a builtin OSD, some 8A 4-in-1 ESC in theory 3S capable DShot600 ready, 1103/11000Kv motors. Associated with the Caddx Turtle 2 (CT2), we have a VTX supporting 48CH with an output power up to 600mW. Good news, the VTX controls can be done via the OSD thanks to the support of the IRC tramp protocol. Let’s discover this news HD Tinywhoop/CineWhoop competitor. BOX CONTENT + 1 x TinyLeader HD + 2 x Stikers That’s all … no battery, no extra props, no printed intruction manual and the more important as you will see no Caddx Turtle 2 OSD board to change the default camera settings. You will have to QRcode in order to download associated manuals. OVERVIEW In theory the TL-HD is a 75mm machine but as you can see, we have here a particular design where front motors distance is about 70mm while rear motor is 52mm. So clearly is not a clear X design and the general diagonal is about 80mm. Now with this particular motor’s layout, can we benefit some better flight behiaviour if a custome mixer matrix is taken into account in Betaflight ? That’s an open question. The lower frame is a simple 1mm carbon frame where each duct system is attached via three screws The duct system for each motor got 5 branches (versus 4 for 75mm machines in general) and jails particulary well each props. -FRONT VIEW The yellow top canopy is 3D printed TPU based. The same as for the Non-HD version. Or here we have a much more wider lens associated with the CT2. The direct negative point is the lower tilt angle we can have, not below 15-20 degrees. For slow motion indoors applications can be a problem. An easy fix consists in cutting/enlarge the hole at bottom position. -SIDE VIEW For the HD version, the 5.8G linear antenna can’t be installed anymore inside the central top canopy hole. It’s blocked by the CT2 main cable. On the front left side, can be found a 2p small connector to plug the OSD board. At least each motor are connected to the ESC via a simple 3 position plug… Good point for maintenance. One of the first really annoying point: the location of the main CT2 button (check inside the red circle in the photo below)… First the receiver is installed here as well…. and it’s pretty tricky to press on it to start or stop recording. More with the default settings of the CT2, the autorecording is not turned on by default. It means you will need to press twice this button for each battery. Take a teethpick to avoid any short while pressing this button. For the 2.4G antenna, at least this one can be installed inside the central top hole dislike the 5.8G antenna On the right side, the microUSB port for betaflight connexion. Good news, with the USD powering, the receiver is also turned on it will make the binding a little bit more easy. -REAR VIEW No lights… but it’s not a big deal. The main lead connector is a XT30 model -UPPER VIEW We can see clearly the original decentralized motor’s layout versus front to rear motors. Notice also the default prop out configuration. It should help a bit more the stabilization of the machine. At least minimizing the projection of grass on the lens. -BOTTOM VIEW Each duct nylon based sustem is attached via 3 tiny screws. The default battery tray is perfect for 300mAh 2S LiPo… but useless for any 3S model. You will need to remove it and use a rubber band instead. What’s a pity that there are no latteral carbon hook to lock the rubber band Probably the most annoying point: the access of the VTX’s button. I spent more that 5min to find it !!!! so small, so well hidden. Look inside the red circle below… Crazy. Even if we have the possibility to control the machine via the OSD, if you want to unlock all VTX limitations (all 48CH and up to 600mW), you will need to press and hold this button more than 20s. -WEIGHT The machine standalond is above 55g!!! a lot of extra weight linked mainly with the CT2. The new Modula 7 HD will be around 46g… so close to be 8g lighter. In comparaison with the non-HD 75mm Trashcan model With a 350mAh LiPo…. So in 3S… clearly is much more an outdoors flyer. Motors and props 1103/11000Kv not too fast for being 3S compatible 40mm quadriblades… classic prop for such machine. Camera module Dislike the Runcam Split 2 mini, the CT2 got a shorter lens with a wide FOV. Paradoxally is probably the trick to be jellofree at least versus the first batch of the RCSM2. It’s now know that first lens of the RCSM2 introduces a massive jello in the video recordings. One fix is to install such kind of wider lens. New batch of the RCSM2 now uses a news lens. Whatever, here with the CT2 we have already such lens. As you can see to downtild the lens, a fix consists in cutting the bottom part. Whateven you won’t be able to reach 0 degrees…. but something about 10 degrees. Why ? because the CT2 main camera body will be also blocked by the two lattera sides. UNBOXING, ANALYSIS, CONFIGURATION AND DEMO FLIGHT First of all, I had to pick up somewhere an extra OSD board in order to change some default CT2 settings. For example, I turned on the auto recording to avoid to press the hidden button twice. The camera is in 16:9 aspect ratio by default and WDR is turned on too. Except these micro-fine tuning, the machine comes with Betaflight 3.5.1 and all default settings are all very well tuned for the machine. You will need just to add the RSSI on the AUX5 in the receiver tab and the RSSI info in the OSD layout. Except that, PIDs, rates, filter settings are very well designed for the machine. I decided to fly mostly this machine in 3S setup in outdoors conditions. First take off with a nominal throttle input about 50%. In order to compare, in 3S it’s just a bit less powerfull than the Eachine Trashcan in 3S. I guess with some weight gained…. can be a different story. In LOS condition, in angle mode, no drifts are observed, a good point for the Gyros…. The machine is fast, turns/banks pretty well…. I already start to like this machine… And now the most important….. In both the FPV live system and on the 1080p@60 videos, there is no jello !!!!!!! OMG that’s so so great….. a real tiny cinewhoop…. I can feel the huge difference with my last SPC-K1 and diatone R249+HD both equiped with the fault RCM2 lens (now they are shipped fixed). The machine is power enough for powerloop, prop wash are very limited…. It’s stable and precise in windfree condition…. Pure fun to fly with. I like this machine a lot. With a 350mAh LiPo, the flight duration was about 3min30s….. Probably with a better battery, I can reach 4min. During my multiple flight sessions, I crashed it many many time and the frame got nothing. A good point for the durability. Before to conclude, be aware that the first batch got some weak FET…. and burnt immediatly as soon as you plug a 3S LiPo. I am lucky to received the fixed batch… and I think now it’s ok. CONCLUSIONS Don’t be impressed by the relatively long list of the negative points. Some can fixed for free, some are linked with a “fast design”…. but the much more important element is here. This machine a real 75mm/80mm cinewhoop able to shoot some jellofree 1080p@60 videos. That’s so so fun. It’s a good acro flyer… not a monster of power but powerfull enough for 90% of your FPV/race applications. It’s durable too for both indoors and outdoors applications. I can only recommend this machine but also have a look to the new Happymodel Modula 7 HD who will be introduce relatively soon. PROS COMPLETLY HD RECORDING JELLOFREE + Well tuned out of the box + Almost no prop wash + Super fun + Durable + VTX w/ IRC Tramp CONS – Heavy – Very bad location of the VTX main button – Bad location of the CT2 main button – No 0 degrees tilt angle for indoors flight (need to cut the canopy to fix that) – Micro SD card insertion/ejection can damage top metal cover of the microSD port – No accessories (spare props, CT2 OSD board, battery) – Battery tray not compatible with 3S batteries – No custom mixer setting for the particular motor’s layout (should be a really a minor point) Dump_BF_3_5_1 This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review.

  23. It’s clear now….. any FPV machine in 2019 will be HD thanks to the one the three HD/FPV combo available (Runcam, Caddx and Foxeer). Here is probably the future best-seller in the 75mm format, i.e. the new Happymodel Modula 7 HD: https://www.banggood.com/Happymodel-Mobula7-HD-2-3S-75mm-Crazybee-F4-Pro-Whoop-FPV-Racing-Drone-PNP-BNF-w-CADDX-Turtle-V2-HD-Camera-p-1418831.html This machine on the paper is just amazing… Listen to: 2S/3S compatible, 69g with a 300mAh/3S LiPo, and the more important with a Caddx Turtle 2 !!!! so ready to shoot 1080p@60 (I hope jellofree) with a low latency FPV signal. It’s not over, the Modula uses now the same super durable frame as the trashcan… Seems to be the same FC F4 based with smartaudio to control the VTX, a builtin SPI receiver w/telemetry and a current meter. My only interrogation are about the MOSFET… Still some 5A w/peak 6A…. Hummm in 3S I hope it will be ok. The machine will be a direct competitor of the Fullspeed Tinyleader HD (review published pretty soon in D-M) but close to be 17g more lighter !!! Want to see a first preview ?

  24. Here is new 2S 68mm tinywhoop FPV racer from HBRC, i.e. the HBX68: https://www.banggood.com/HBX68-68mm-1-2S-RC-FPV-Racing-Drone-PNP-BNF-F3-10A-BLHeli_S-800TVL-0802-16000KV-Motor-p-1416705.html It’s still based on a old F3 + OSD board…. but now there are some builtin 10A ESC !!! so really no problem to handle 2S voltage (and maybe more …). The machine includes a AIO combo FPV camera with 48CH and with three outputs power: 25mW/100mW and 200mW. No information if there is a IRC Tramp or SmartAudio support… probably not… Motors are these new 0802/16000Kv model… In a first glance, this new HBX68 is not advanced as the Eachine trashcan (probably no smartaudio, no F4 FC) but the main pro point of this machine is its weight about 27g (with the receiver included) so clearly 5-6g less than the Trashcan. In 2S configuration, this machine should be around 42-43g… not so bad for indoors applications.

  25. INTRODUCTION The new Diatone R249+HD is a new candidate as 2.5″ HD FPV racer. This model comes after the SPCMaker K1 and the iFlight iH2 all of them includes the last Runcam Split Mini 2 combo, able to film in 1080p@60fps while broadcasting the FPV signal with low latency. As you already maybe know, it’s a real real challenge to build a 2.5″ machine jello free for the HD recordings… For example, the SPCMaker K1 failed this main objectif. For larger model, it’s much more easy to get rid of all vibrations transmitted…. but in a such compact tiny space, it’s another story. The R249+HD got a F4 flight controller, some 20A 4-in-1 ESC with Dshot 600 support and 1105/5500KV motors Notice this machine is shipped only in PNP version… so you will have to provide your favorite receiver. Let’s have a look to this new HD flying plateform. BOX CONTENT + 1 x Diatone R249+HD + 4 x 1940 Props (2 CW, 2 CCW) + 4 x 2540 Props (2 CW, 2 CCW) + 4 x Prop guards + 1 x MicroBuzzer + 1 x Male XT30 connector + 5 x zip ties + 1 x Spare battery strap + 1 x set of M2 hexscrews + 1 x bag of M2x7mm hexscrews + 1 x 3M tape + 2 x M2 nylon nuts + 1 x FC connector A lot of accessories are given except spare batteries. Diatone advertised that the best results are obtained in 3S with a 450mAh LiPo. OVERVIEW Versus the SPC-K1, the R249+HD got much longer arms to reach almost the 115mm size while having a shorter central body. The unique bottom plate is 3K carbon based with 3.30mm of tickness…. as the SPC-K1. It will be strong enough for crash durability, but maybe not enough for transmitted vibrations from motors. From motors, ESC and flight controller everyting is branded by MANBA. The Mini version is installed on the R249+ with three UART port (U1,U3,U6). Very important remark, non of these Uart are bidirectional…. it means no direct plug & play of F.port compatible receiver. ESC are strong enough for 4S input up to 25A@peak. The Side-By-Side comparaison with the SPC-K1 …. The K1 got more a H design… while the Diatone is more a X-based. -FRONT VIEW The general design is pretty cool and cute…. advantage IHMO for the Diatone…. We have this plastic top canopy structure surrounding all the electronic tower and the camera system. With a 4S LiPo installed beneath. -SIDE VIEW The quality build is very good… with a clean setup, clean soldering job…. with sillcone wires everywhere. The RCSM2 main board is protected with the white plastic cover. Above, the Runcam 5.8G VTX board supporting up to 40CH and two different output power (25mW and 200mW). Great news, thanks to the IRC Tramp protocol, the Vfreq, Vband and power can be set via the OSD. It’s a good point that the SPC-K1 don’t have. But it’s not perfect …. there is no wiring connextion between the RCSM2 main board with the last UART6 available. What’s a pity… because we could control the camera like this…. Only 2 wires are missing between the two elements… What’s a pity. Anyway, the R249+HD comes with a free 5p connector. This one allow a direct connexion of the FrSky R-XSR receiver in SBUS configuration. In a first glance, it’s a good point ….. but …. with the way of connexion, no way to receive the RSSI for the OSD for example. If you want the RSSI as well …. (and telemetry in general), the full 5 wires connexion is required… Or it’s not the case here. 3 on 5 are here only. The S.port in & out are missing. Another alternative would have been to connect the receiver with the new F.port protocol…. this one share on a bi-directional data transmission on the same wire …. but but but requires a UART able to be bi-directional. Or the MANBA don’t offer such UART capacity…. So to plug the R-XSR in F.port format, you will have to solder the signal wire on the uninverted pad on the receiver itself… To resume…. if you want RSSI on your OSD & telemetry…. you will need to play with the soldering iron. More the R-XSR is one the most expensive reveiver… This is why I decided to install more a simple OpenFrSky receiver instead… in D8 mode, sharing the RSSI on the last channel but also having telemetry. This receiver is connected via SBUS Connexion. -REAR VIEW A compact caps is here to filter as much as possible interferences from noise & ESC…. Unfortunatly, it’s not yet perfect, some noise can be noticed in the FPV feedback With the R-XSR direct plug & play but without RSSI Or with the OpenFrSky receiver installed and protected inside a heatskrink tube. -UPPER VIEW -BOTTOM VIEW -WEIGHT 126g in 3S (350mAh model)… so close to be 8.6g more heavier than the SPC-K1. Motors and props Two set of props are given… a first 1940 crystal one assumed to offer the best results for HD recordings. and 2540 larger model. The free gap available with the 2540 is less than 1mm …. impressive. The M2 hexscrews to lock each prop. Camera module The runcam split mini 2 lens is not protected from a frontal crash. Notice the tilt orientation can be set from +10 up to +35-40 degrees. Notice also it’s not last lens model given now with a Runcam Split Mini 2. The new and shorter one is annouced to reduce a bit the jello. UNBOXING, ANALYSIS, CONFIGURATION AND TESTING As already mentioned, I installed the OpenFrSky nano receiver with SBUS connexion… so I add to remove the 5p microJST connector. The machine comes with Betaflight 3.5.1 pre-installed and I can say relatively well fine tuned. With this particular type of receiver will have to invert the serial line with the “set serialrx_inverted = ON” command in the CLI. Before to go forward, IMHO the main important point to check first is the presence of Jello in the HD recordings….. If yes, the interest of this machine is almost 0 at least compare to a non-HD and cheaper model. To check this, I stayed in my garden in a perfect windfree conditions… and in 3S configuration as mentioned by Diatone. I first used the original 1940 props …… and as you can see the results are just awfull !!!!!!! So wavy/jello…… it’s just unacceptable. So let’s try with the 2540 ….. well …. it’s just a bit better but far far far away from acceptable results… In order to make a faire comparaison, I also include what’s results can be obtained with the SPC-K1. This one got much less jello…. in exactly the same situation/setup…. but for me none of them are just ok…. Too much jello in any case… Ok I tried to applied the filtering settings of the SPC-K1 machine with the PIDS of the R249+HD…. and here results are almost as good/as bad as the SPC-K1… I also tried to play a bit with other PIDs and filter settings but without really good success…. As you already understood, the main important test, i.e. to produce Jellofree videos completly failded…… I don’t see any interest to continue to test its FPV racing capacity…. No doubt there are good…. but this machine should be first of all a low riding HD recorder…. CONCLUSIONS Unfortunatly the quest to have the first 2.5″ HD FPV machine is still opened….. This diatone in practice offer even worser results than the SPC-K1. Maybe because there is no soft-mounting for motors ? or the RCSM2 uses the old lens ? Whatever if these two fixes would be here…. I don’t think it will solve 100% of the jello…. As you already understood, I can’t recommand this machine as 2.5″ HD FPV machine…. Take instead the non-HD version…. cheaper…. Who will be the next brand to attempt the quest… We will see…. PROS + Super compact 2.5″ HD FPV racer + Quality build + A lot of accessories in the bundle + VTX w/ IRC tramp support + Builtin Runcam Split Mini 2 CONS HUGE AMOUNT OF JELLO OUT OF THE BOX !!!!!! UNACCEPTABLE FOR A HD MACHINES – R-XSR S.port connexions absent – MAMBA FC don’t support directly F.port connexion => Need to solder the F.port signal wire on the P uninverted pad of the R-XSR – 8.6g more heavier than the SPC K1 – Absence of Soft-mounting for motors Dump_249+HD This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review.

  26. INTRODUCTION The Eachine Trashcan 75 was one of the most awaited machine after the great success of the first and compact 75mm 2S tinywhoop machines, i.e. the BetaFPV 75X and the happymodel modula 7. The Eachine answer on the paper is just incredible: all last electronic novelties are here: 0803 motors for 2S power, F4 flight controller with a builtin OSD, a programmable VTX via smart audio, a builtin SPI receiver (FrSky, FlySkay and now Speltrum DSM2/X), a new 1/3″ 1200TVL Caddx FPV camera and a frame revisted to be more durable than the Modula 7 for example. So everything in theory is to have a future hot cake seller. Let’s check if in practice, it’s the case. BOX CONTENT + 1 x Eachine Trashcan 75 + 1 x USB charging cable + 4 x Spare props (2 CW, 2 CCW) + 4 x 300mAh 1S LiHV batteries with JST PH 2.0 connector + 1 x Screwdriver + 1 x Bag od spare screws + 2 x 3M tape bands + 1 x 1S plug + 1 x Spare XT30 lead connector + 1 x Allen key + 1 x Prop remover tool + 1 x Instruction manual (English) + 1 x Transportation bag As last ReallAcc, Jumper, happymodel and Eachines deluxe products, the instruction manual is extremely well done…. It’s so rare so it has to be noticed. Printed in color, you can find all the different steps to bind, programm your VTX and OSD. A very important accessory (to not be lost): this plug is used to power your Trashcan either in 1S (with the plug installed) or in 2S (plug removed). OVERVIEW The machine comes in 75mm format …. so look like a giant versus the little 1S US/UR 65 brother. But don’t be afraid, the more important will be the total weight in practice. -FRONT VIEW As last 1S brushless FPV Tinywhoop machines, the Trahscan 75 comes with a nice red canopy. The plastic quality is really good. Flexible enough to absorve energy of shocks. On the front part, the cage welcoming the Caddx Eos2 camera can be oriented from 0 degrees up to +35 degrees in practice for more agressive and sporty flights. I will anticipate a bit, but in order to fix mostly the presence of vibrations/jello, insert a piece of foam (the one coming with the transportation of the Trashcan) in sandwich between the FC and the red canopu structure. Il will remove most of vibrations. -SIDE VIEW -REAR VIEW A 5 LED bar is here pre-programmed with a larson scanner effect. No turning indication done… You can easily add it in betaflight in the LED light section. -UPPER VIEW The transparent red canopy let make visible all lights coming from the FC, especially for the two rows of lights for the Vfreq and Vband selection respectively. One negative point: the hole where the linear antenna pass through is too large and there is a free loose/gap. In practice, it means than the antenna can rotate and in the worst scenario , the uFL plug can be pop out. -BOTTOM VIEW Installed in a 2layers configuration, a free loose can noticed for the battery installation in the tray. Two 3M tape are given to fix this gap. Probably the best solution is to use a rubber band. Good point, each motors are connecter via a microJST plug: perfect for motor’maintenance. The green wire corresponds to the Smart Audio connexion. Notice there is a physical microswitch to bind the machine to your transmitter….. but hard to access. It’s located nearby the microUSB plug…. below one of the two plastic bars of the battery tray. As we will see, I advise more to bind the machine via the new CLI command… it’s billion of times more simpler -WEIGHT 33.9g standalone …. no it’s not lightest 2S TW racer… You can save a fraction of gram by removing the red led strip bar for example. For 1S setup and for 2S/oudoors So we are just under 50g …. still of for indoors but for more larger living places IMHO. 1S is advised in this scenario. 2S will be too throttle touchy. Motors and props The new 0803/15000Kv motors…. just a fraction of gram more heavier than the classic 0603…. but much much more powerfull. 40mm quadriblades props…. with 1.25mm shaft diameter. If you want to improvel also the flight duration…. The two/triblades setups must be adopted. LiHV battery 300mAh 1S LiHV batteries…. announced to be 40C/80C (so probably more 40C)… Be aware with LiHV batteries, they tend to loose more capacity versus charge/discharge cycles. In comparaison with the 1S 250mAh coming with the US65mah…. longer but really more heavier. So for our UR65/US65, this model of 300mAh can be interesting too. A USB charger is provided. The microswith selects the LiHV (default) and LiPo mode. When turned on the direction of the USB plug, the charger is in LiHV mode (up to 4.35V/cell). When charging, you see a solid red light. It’s turned off when the charge is done. Camera module The Trashcan 75 integrates a new Caddx EOS2 CMOS camera with 1200TVL !!!! It’s based on a 1/3″ sensor… Don’t be abused with these number…. In practice, higher TVL means also higher latency and mor noise in the signal especially for low light condition. The new Caddx promises a builtin WDR feature…. so we will see in practice. The VTX got 5 bands (raceband supported) but not an exact 40CH. Some Vfreq are restricted to be FCC compliant. Probably there is a way to uncock this limitation. The VTX got a physical swith… but as for the receiver, I advise more to tune the VTX via the OSD or CLI commands. If you upgrade the current betaflight version, be sure to turn on the TBS protocol for the UART1. The UART3 is free to be used… why not to trigger a Runcam Split Mini 2/Caddx turtle 2. UNBOXING, ANALYSIS, CONFIGURATION AND DEMO FLIGHT The machine comes with a beta version of the future branch 4.0 of Betaflight. It’s not a problem at all, this RC is very stable in practice. When you connect the machine to betaflight…. you can notice that Eachine spent some time to tune/optimize parameters…. That’s so great. For example the TBS smart audio is working with the UART1. The PIDs have been optimized, the rates, the flip over crash is active for AUX3 by default, the OSD layout and even the led strip bar…. what is missing ? ho…. just a minor detail… to turn the buzzer for poor man…. by turnin on the two correspoding options in the configuration panel…. Not a big deal… So bravo Eachine for this. The Trashcan 75 offers a great new feature!!!! You can bind the builtin SPI receiver via a CLI command!!!! That’s just great… No need to have a second, third hands and do tricky moves to keep pressed the microswitch bind button while powering the buttom…. It’s so easy now…. with one cup of coffea in one hand, run the binding sequence of your transmitter then go in CLI and type the “bind” command….. and voilà :)…. Disconnect everything (USB plug for the Trahscan and power off the transmitter) and reconnect… you are bound… How I can live now without this feature ? Of course it will work only I guess with SPI receiver. To complete, I just did minor changes for the OSD layouts and also change the AUX mappings to turn on the buzzer for poor man…. Important point, if you want to turn the 200mW setting via OSD, you will have to select the 800mW one. All other ones via OSD select the 25mW output. Now … it’s time to talk about the performances of this machine…… When you plug the first battery … no light. It’s only when the second is plugged than the ESC will start to music. I check wires …. to not be in contact …Then first throttle up… and the machine felt like a stone…. … nothing really blocked… I rearmed… and no more problem…. Really stange… I noticed that behaviour only for cold start session…. So don’t be surprized… Ok now the machine is in the air !!!! and in angle mode no drifts at all in angle mode Yeahh!!!. It’s rock steady stable. Impressive… Let’s attempt a punch out …And whaoohhh that’s a power, really not bad at all…. and during fast descents the prop wash is here but still managable. In LOS, this machine is super precize…. what’s happyness….. Now it’s time for FPV time …. The FPV camera signal is good …. but not among the best in term of WDR at least…. Dont’ worry, the job is already well done. The range and FPV distances are also pretty good IMHO…. I already love this machine…. Ok a bad point…. there are some jello in the FPV signal…. Install the piece of foam and it will improve the situation. This machine is super powerfull….. power dive, powerloop …. fingers in the noze….no instability at the end of such figures… That’s great…. A real pleasure to fly this little monster outdoors. For indoors, 1S is highly recommanded coz the throttle is too touchy in 2S. Another complain…. the flight time don’t exceed 3min and even 2min30 with agressive accro flight style. It’s not enough. You can use the provided XT30 connector if you are sure to fly this machine in 2S setup only … or solder more a red JST connector instead. Compact 2S batteries are more easy to find with this connector. I crashed this machine many many times….. and the frame is still ok…. Ok if happened at full speed against concrete…. don’t expect miracles. At least to change a frame, it will take 5-10min maximum. Spare parts are already available. CONCLUSIONS Definitively a high entry Eachine model, a keeper model…. It’s almost a perfect machine for winter proximity FPV flights. It’s powerfull, durable, with ton of features…. Both the FPV and control range are good…. Only the out of the box flight duration is too limited and another battery setup will be required as upgrade. PROS + Powerfull 2S machine + Tons of fun + Very well designed + Almost perfectly well configured out of the box + F4 powerfull FC + Smart Audio + Builtin SPI receiver + No drift in angle mode + Good FPV camera + 25mW/200mW VTX + Good FPV and RC ranges + CLI bind command + < 50g in 2S setup + Frame among the most durable + Can be used for both indoors and oudoors applications + Transportation bag CONS – 2.45 min of flying duration in 2S – Presence of Jello (can be fixed) – Antenna need to be 100% secure with a drop of glue – Potential receiver cuts for the first take-off dump_BF_4.0.0.txt This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review.

  27. INTRODUCTION The Eachine E511S is a new advanced WiFI Toysquadcopter with brushed motors but with GPS & barometer flight assistance. The Eachine E511S is proposed in a basic 720p+2.4G WiFi link, an intermediate (1080p+2.4G) and an advanced (1080p+5G). I will focus on the 1080p@2.4G version. It’s a foldable machine easy to transport inspired by last DJI designs with a builtin 1080p@25fps/5mpx Cmos sensor. More the tilt orientation can be controled via a 1-axis micro servo controller via the radiotransmitter. Associated with the GPS presence, the iOS/android application offers: RTH, orbit mode, path planning and GPS-follow-me functions. In term of price segment…. the E511S turns around 100USD…. so a bit expensive for a brushed Toyquadcopter but twice cheaper the than Hubsan H510S for example. Let’s discover this product. BOX CONTENT + 1 x Eachine E511S + 2 x 1200mAh 2S LiPo (proprietary battery) + 1 x Transmitter (using 4xAAA batteries not included) + 1 x USB charging cable + 2 x Spare props (1 CW, 1 CCW) + 4 X Prop guard + 1 x Screwdriver + 1 x Instruction manual (English) The instruction manual is badly translated and the results of many upgrades versus earlier Eachine products. For example, the transmitter button list is not fully exact. OVERVIEW The machine folded occupies a 15cmx10cm rectangle and unfolded the E511S is close to be a 350mm machine. In term of structure, it’s a 100% plastic one. The general quality of the plastic is good with two types of plastic for the canopya and for the arms. -FRONT VIEW Two white front LEDs are here to help you to keep orientation in LOS conditions -SIDE VIEW -REAR VIEW The battery compartement. No difficulty to insert or to extract the battery. It’s a good point. On the top rear location, the barometer sensor is installed. -UPPER VIEW The E511S show a column of 5 LED lights. They are flashing until the GPS system fixes at least 7 satellites. As soon as it’s done, lights become solid. A unique power button. Hold 3s to turn on/off the machine. -BOTTOM VIEW A little bit hidden, the microSD slot to welcome a card up to 32Gb. For the 1080p only model, we can find the 2.4G antenna of the WiFi builtin module. -WEIGHT 290g without propguards…. so exceeding the 250g limit…. Motors and props 1020 brushed motors…. They are associated with a gear/pinion of course to increase the lift capacity. In the other hand, the stress on motors is increased. And the main open questions will be the durability of these motors and the availability of spare. Don’t expect more than 30 flights without problem and be sure before each take off/crash to inspect manually the free rotation of each props. LiPo The E511S is proposed either with a 1, 2 or three batteries in the bundle. They are basic 1200mAh 2S LiPo with the 2S balancer plug available The USB charger shows a red light for USB connexion, a flashing green light for charging and a solid green light when it’s charged. Full charging takes about 2h…. it’s long. I strongly advise to make a DIY charging cable to be plugged on your favorite professional charger. Camera module Since close to one year, most of toysquadcopter come with a wider Field of View more compatible with video filming application. Here we have a 120 degrees model. The lens is by default oriented to -45degrees after eaching booting. You can set the orientation from 0 degrees down to -90 degrees. The camera record in 1080p format with a datarate about 5mbit/s… Far from 50Mbits+ for advanced and more professional video plateform. Only 25fps in term of frame rate….. but at least the recording seems to not loose too much frames over time. A raw sample recorded on the microSD card Notice the presence of vibration and props occlution when the gimbal is set to horizontal. The color rendition is better than we can find usually for toyquadcopter…. the light sensitivity also….. but we are still (very) far from even a Xiaomi Mi A3 in term of video quality. Disassembling To open the machine will have to unclip first two parts: the very top canopy structure surrounding the power button and the two latteral silver plastic tabs. After, you will be able to access to all screws to be removed. On front, the camera is held by a servo block motor. 4 screws attach the system and the camera is plugged to the main WiFi module via the orange rubbon cable to be detached as well. The GPS chip on front, the barometer rear. The shielding for the GPS module is here. Transmitter The same Eachine radio chassis we can find with their last product. 4 shoulder buttons and 6 front ones. To take off with the radio transmitter you need first i) to receive at least 7 satellites, to ii) calibrate the compass (press the left arrow button to start the calibration procedure) then iii) press both sticks in bottom outter direction to start the engine. To start a video, you can press the top right shoulder button. To take a photo the rear right shoulder one. Notice, if you inserted a microSD card, the recording will be done on it. If not, the recording will be the received video flux on your smartphone. Ni-Mh 4xAAA batteries are working but they need to be very well charged to be able to turn on the radio Without problem you can use a 6″ smartphone…. with a bit of extra force, I was able to use a 6.26″ model…. but for larger model no more room available. UNBOXING, ANALYSIS AND TESTING As said in the introduction, I received the 1080p version but also including a 2.4G WiFi Link…. so no problem for android connexion (can be a problem for the 5.8G version and android europeens users). No password required. Notice with the last software android version, now the 1080p preview and metric unity are here. Before each take off, it’s strongly advice to perform a compass calibration to be sure to have best GPS holding results. You can run the procedure either with the left arrow button on the RC or via the option in the app setting menu. First rotate three times clock wise the machine horizontally until the transmitter emits a beep & the app shows to change to the Y axis then install the machine noze down and rotate one more time clock wise three turns until a second beep. The application is largely inspired by the X-hubsan application…. and I feel it’s the same team who developped the software. For example all flight mode selection is the same, the way-path planner uses the same principles, etc… It’s a good thing I think since the Hubsan app is a good one…. Except that the E511S is not fully polished IMHO. For example, the google map is not automatically centered on the drone location for example. The Orbit flight point of interest selection was not clear also. To fly the E511S only with your smartphone, you will need 1) to let appear the virtual sticks, 2) to press and hold 3s the lock button, click yes to confirm the take off and then 3) press the auto-take off button. The machine can fly only in GPS stabilization mode and I can say it’s stable !!!! rock steady… not bad for a toyquadcopter. The machine offers 3 speed modes via the radio and only 2 if you plan to fly the machine only with your smartphone. The video feedback is not bad at all… precise…. and I was also positively surprized to see a good link up to 100m. In winter time with a low sun, don’t expect miracle with the camera sensor…. but resuts are acceptable. Of course no EIS and this machine is in practice usefull only in windfree conditions. The RTH is very precise in practice a good point. The way point definition super easy thanks to the draw options. I don’t why, the machine waits a couple of second in each waypoint even if set to 0 in settings. Now it’s time to more negative points…. the first one is about the battery duration… we are far from the 13-16min advertized…. more about 10min… and notice the huge voltage drop under load…. sign of poor default batteries. Another problem I had …. the servo motor of the gimbal stopped to worked after 4-5 flights I never tried to force on the mechanism….. so a weak point of this machine main certainely. Concerning the follow-me GPS based, I also noticed than the machine was not perfectly on-axis with the holder of the smarphone. Maybe a biased link wih the GPS fix option available in the parameters. In general such king of follow-me obtains results far to be perfect….. slow/delay in reaction and of course time to time unfocusing the target. Look attentively to the vibrations transmitted at arm’s extremity….. the main source of jello in the video…. CONCLUSIONS I have a strange feeling with this machine. In one hand, I found this machine easy to fly, with godo advanced features usually no present in toyquadcopter segment. Camera results are better than usual…. it’s 1080p… color are correct, frame rate still a bit slow but without frame lost at least. The radio and FPV range are ok… the application user friendly…… but in another had… it’s about 100USD ….. and with almost this price you can find a MJX bugs with a 1080P camera as well but with brushless motors…. Functionalities are the same more or less. At least the E511S is foldable. If I go further, for 200 bucks we have the FIMI A3…. so the real question if you have to ask if you plan to purchase the E511S. Do you want a first machine to shoot basic but working 1080p videos to enter into the drone’s world…. or if you want wait a bit more to afford for example the FIMI A3. That’s the question. PROS + Cheap GPS quadcopter + Very stable GPS hold + 1080p camera @25fps + 120 degrees FOV + Good radio and FPV range (at least 100m) + 1080p version includes a 2.4G WiFI + 1-axis contralable gimbal (only via the remote) + Better color and light rendition than previous generation CMOS sensor (but still far from average 1080p results) + Foldable + Good quality build CONS – Jellos linked with vibrating arms – Fragile 1-axis gimbal servo motor – 8-9 min of flight time – Voltage drop under load – Can’t install 6.2″>+ smartphone – Android software not yet mature: not saving all parameters, not center map on the quad’s position, etc… – No selfie drones specialized flight modes This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thank them for this attitude.
