INTRODUCTION

The Eachine QX110 is probably the fifth or sixth inputs in QX’s serie. With ths new model, we have a compact brushed microquadcopter with V-tail architecture. A V-tail design should offer in theory much more yaw authority especially in full speed. More, like the QX105 “Bat”, the FC is F3 omnibus with a builtin betaflightOSD chip. Like most of recent Eachine racers, three choices of receiver are proposed: FySky AFHDS-2A, Spektrum DSM2/X and FrSky in D8 mode. Let’s discover the bundle

BOX CONTENT

A nomark box jails the QX110 but everything Inside is well protected.

null

+ 1 x Eachine V-tail QX110 (with a 1S 600mAh LiPo ending with microLOSI connector)
+ 1 x USB charging cable
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x Spare 600mAH LiPo battery
+ 3 x Velcro bands
+ 2 x Rubber bands
+ 1 x AIO camera tape
+ 1 x Prop remover wrench
+ 1 x Instruction manual (English)

OVERVIEW

The QX110 is paradoxally a 100mm machine with Vtail system, i.e. the two rear arms are inclined of 45 degrees. If the positve argument is stronger torque during turns, the potential drawback is the potential lost of thrust for vertical ascent in general. The machine is almost 100% 3K carbon based. Only few plastic parts are here. Bad news, in order to save some weight the thickness of the arms is relatively thin.

Arms are only 1.5mm … more the central part is empty :(…. IMHO, they won’t resist to a big crash

-FRONT VIEW
With the Vtail system, the machine seats on the two front motor’s pods and the rear landing skid. The AIO FPV camera is taped on the red aluminimum camera support.

null

I regret that the red props are installed on rear motors instead on front ones.

With the battery installed

null

-SIDE VIEW
All motors are connected via 1.25mm 2 pin microJST connector, a good point for maintenance

null

On the right side, the microUSB port super to access

null

The AIO camera can be uptilted up to 20degrees via the two latteral screws

null

-REAR VIEW
null

Good news, new default settings of the 4 light’s bar now directly integrates a Larson scanner effect. The two external shows turnings and the inner ones more the throttle activity

null

The vtail system is based on this orange plastic part where the two rear arms are screwed. I feel this system less weak than the V-tail system of the Eachine 210. It should resist relatively well to crashed.

null

At least if a rear arm break, it should be relatively easy to replace it with a new one.

-UPPER VIEW
A buzzer is installed on top jailed into the top carbon plate so well protected.

null

On the front left side, the bind button for the builtin FrSky

null

-BOTTOM VIEW
null

With the battery attached via the velcro bands.

null

-WEIGHT

45.8g standalone

null

up to 62.8g with the battery attached so in practice more than 5g more heavier than some QX’s models. It will impact on both the flight duration and general thust capacity.

null

Motors

Well jailed into a platic motor pods, we can find some 8.5mmx20mm coreless brushed motor. I don’t think they are boosted on steroids but just basic model.

null

Props are 55mm long.

Camera module

The same AIO camera, a 600TVL CMOS sensor based. 48CH channels are supported by the 25mW. A 5.8G linear has been prefered versus a cloverleaf model. Two buttons can be found. The front one when shortly pressed Mirror the video signal. If long pressed, you can choose between the NTSC & PAL format. The rear button can select one of the hight Vfreq when shortly pressed and one of the six Vband wien pressed more than 2s.

null

null

null

Notice, the 2.4G is correctly installed vertically relatively far from the 5.8G antenna

null

The linear 5.8G antenna is badly installed, probably for transportation. In this position, the FPV range will deeply impacted. Please gently bend it vertically.

null

UNBOXING, ANALYSIS, BINDING AND DEMO FLIGHTS

Here are the default PIDs settings

null

Notice the low value for the yaw command… and the super high for D in general. The rates are also slow …..

I really appreciate the FPV camera with bright and vivid colors and its realtively good PFV penetration despite being only a 25mW model and with a linear antenna. The OSD informations is also a strong positve point to monitor at least the battery voltage. Ok to make short, with the default PIDs & rates settings the machine have a weird behaviour when turning… if you are engaging a fast turn, at the end of the move, the machine glide from the rear side and you can rotate easily or 30-40 extra degrees. …. I guess the yaw-P value is too small … and in general all PIDs settings must be reworked totally. The machine presents also a lot of woobles, bouncings back. To resume it’s not super fun to fly out of the box the QX110. Punchouts are correct but not amazing to be honest. .. The QX110 would deserve to save 4-5g to be more sporty. The flight time are in average of 4min30…. Could be also better but with V-tail architecture, we are loosing part of the rear thurst.

CONCLUSIONS

An interesting machine but one more time, the devil is in the detail …. here, the PIDs settings are faulty and out of the box this machine is not super fun to fly with. It’s a real pity because, all ingredients are good… Super strong FC F3 board with a builtin OSD, good AIO FPV camera, builtin buzzer, etc… I regret also the potiential breakable 1.5mm arms absoluptly not adapted for indoors flights. But I am confident that some much better results can be obtained with some little works on PIDs.

PROS

+ Great Omnibus F3 board with BetaOSD chip
+ Original V-tail design
+ Betaglight
+ Good FPV camera
+ Ajustable uptilt angle
+ Builtin buzzer
+ Programmable LEDs’s light
+ FrSky D8 with RSSI

CONS

– Fragile arms
BAD FACTORY PIDS SETTINGS
– No super strong punchouts
