This is a pre-release version of the Youbi XV-130 review. More videos and details will be added later

INTRODUCTION

Here is a more or less a direct clone of the Rotor-X Atom V2 with the Youbi XV-130, a compact 130mm brushless racer with strong 1306 motors and 20A BLheli_S ESC. The direct inspiration of the Atom V2 is obvious with 3″ quadri-blades props. Let’s compare/highlight the difference/improvement of the Youbi XV-130 versus the orignal non-chinese version. The first main avantage of the youbi is clearly the price… close to three times more cheaper.

BOX CONTENT

null

+ 1 x Youbi XV-130
+ 4 x Spare props (2 CW, 2 CCW)
+ 2 x Receiver plugs (1 for PPM, 1 for SBUS)
+ 2 x Battery velcro straps
+ 1 x Instruction manual (English/Chinese)

OVERVIEW

As said previously, the copy with the Atom V2 is clear, the type of profiled canopy. Here the canopy’s plastic quality is correct, but won’t resist to a massive crash. On top, a 5.8G linear antenna installed vertically.

null

In comparaison with Tarot TL130H1, where 1104 more are prefered.

null

null

-FRONT VIEW
null

-SIDE VIEW
Any visible port to tune settings for the SPF3 board… no choice you will have to remove the top canopy section

null

null

A basic mod consists in create a direct USB port access….

-REAR VIEW
A novolty,for the Youbi XV-130 instead of JST or XT 60 connector, we have here a XT30, smaller and lighter connector.

null

-UPPER VIEW
null

The gap between the canopy and props is very narrow. 3-4mm for front and even less for the rear section

null

null

It means, that after each crash, you will be to check of arms are not bent since despite 2mm of section, there are still flexible.

To hold your receiver’s antenna, you can drill small holes through the canopy

null

-BOTTOM VIEW
A unibody lower plate of 3K carbon of 2mm of thickness.

null

Be aware, the arms remains a little bit flexible. If you break an arm, you will have to disassemble everything.

-WEIGHT

null

null

With a 4S 500mAh LiPo, the total weight don’t exceed 190g

null

Motors

Strong 1306 motors, 3600 Kv are installed, 10g each

null

null

Shaft section is 4mm (like the XK X251)

null

null

In comparaison with 1104 tarot motors

null

Props are 3″ models quadriblades, to more precise some 3030 model

null

null

LiPo

I opted for a light and compact 4S 500mAh LiPo directly equiped of the XT30 connector

null

IMHO, the best choice should be a 600-700mAh model still in 4S.

Camera module

null

Announced to be a 600TVL CMOS PAL camera with 100 degrees of FOV. As you can see, the camera is installed on a 3D printed suppert inclided of 15 degrees approximatively.

null

No possibility to tune the uptilt angle unfortunatly ? for agressive FPV flights, the default angle is not enough….
More the light sensitivity is really poor and in practice, you can be completly blind face to the sun. The same symptom as for the Tarot TL130H1 … Probably no associated WDR.

A raw video sample

For high throttle inputs, some jellos/vibration are noticable. maybe by inserting some foam elements around the camera, the effect can be reduced. Better PIDs/TPA settings should help too.

If you don’t like the default 100 degrees for the FPV, the lens thread is in M7 format, so easy to find a replacement candidate

null

Video transmitter

null

A unique white button nearby the RP-SMA connector permits to select the frequency band (5 bands supported), the frequency and output power mode.

null

To enter into the band selection, press 2s the button. Then band letters should cycle. When you favorite band is selected, short press the button.
Then by short pressing, you can select one of the 8 internal frequencies. To save the configuration, long press 2s the button. A small red dot should appear in lower right position.
To select the output power, you have to keep pressed 6s the button. Then pressing the button 3 digits are displayed. 1 for 25mW, 2 for 200mW and 3 for 400mW. One more time press 2s to save the setup.

Disassembling

Remove the two M2 hewscrews on top and open it by rear side first

null

null

null

null

null

after the installation of your favorite receiver

null

For me a Superior Hobby FrSky D8 SBUS SRP8 model

the microUSB port of the SPF3 board on the right side

null

Below, 2 free UART ports where you can plug an OSD board if you want

null

The left side welcomes the receiver port. Two cables are given either for PPM or SBUS connexions

null

The RP-SMA connector is mounted vertically. During a major crash, the connector can be damaged

null

Maybe by adding some hot glue around, it could help to secure the system

The bottom face of this upper board is nothing else than the SPF3 section.
null

You can notice the absence of a buitlin buzzer… desipite to be a must to have for such compact size.

The inner board is the 4-in-1 ESC/PDB board.

null

ESC are rated 20A and supporting BLHeli_S technology. Be aware by default, oneshoot 125 is selected in betaflight, not multishoot.
If you select multishoot (advise), you will need to change the minimum throttle to 1040 and minimum command to 990. Maybe we can regret non-individual ESC but the system would have been more heavier too.

null

UNBOXING, ANALYSIS, CONFIGURATION AND FIRST DEMO FLIGHT

CONCLUSIONS

The positive points of the Youbi XV-130 is clearly the1306-BLheli_S ESC combo offering in practice a huge amount of power for such compact size. The SPF3 FC brings also super fast PIDs loop for ultra smooth flights. Announced to be sold around 130 USD, the price represents also the massive argument in favor of the Youbi. Anyway, this product is far to be perfect…. especially the FPV camera is a really poor in term of light sensitivity where you can be almost blind for under-exposed areas. If you are interested by this machine, it’s strongly advise to upgrade the FPV cam asap. The flexibility of arms seems to introduce also some vibrations at high throttle inputs. Better TPA ajustements and probably introduction of foam should reduce this artefact.

PROS

+ Design cloning the Rotor-X Atom V2
+ 20A BLheli_S ESC
+ SPF3 board
+ Flashed with last Betaflight
+ Strong and powerfull machine
+ 3 VTX output powers (25mW, 200mW, 400mW)
+ 3K Carbon based

CONS

– Poor light sensitivy of the FPV camera
– No direct USB access
– No builtin buzzer
– FPV camera uptilt angle blocked
– Frequency list table partially false
– Vibrations for high throttle inputs
– Flexible 2mm arms
– 5.8G Linear antenna
– (no OSD)

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.
You can find it actually for 28USD at http://www.banggood.com/Cheerson-CX-10C-CX10C-Mini-2_4G-4CH-6-Axis-RC-Quadcopter-with-Camera-RTF-p-989909.html
