In 2014, nanoquadcopters invaded all the quad market with for example the famous CX-10. Here, a new model, the FQ777-124 offers 3 (new) features : i) Headless mode, ii) one key return and iii) pocket transportation. This FQ777-124 looks like the perfect gift for quadcopter beginners and/or for office entertainement.
+ 1 x FQ777-124 “poket drone” (with a 1S 100mAh LiPo )
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x USB charger cable (using 1.25mm mini JST connector)
+ 8 x Spare props (4 CW, 4 CCW)
+ 1 x Prop guard
+ 3 x landing legs
+ 1 x Instruction manual (english/chinese)
In comparaison with the WLtoys V676
You don’t need to remove props to install it.
8 spare props are provided. It’s a really good point
12.3g standalone so 0.3g more than the CX-10 and the exact same weight tnan the CX-10A
With the landing gear added, the extra weight is almost 0
4 screws to remove to splut in 2 parts the canopy
The LiPo is a 1S 100mAh directly soldered on the power connector pads.
The CX-10 reference is clearly indicated. The FC is identidical. Problably, they updated the CX-10 green board with a new F/W including the “one key return”. The antenna is patch model directly included in the PCB just below the CX-10 inscription
Motors are identical to the cheerson CX-10 and for most nanoquadcopter, some tiny 6mmx12mm coreless model.
The main orignal part of this model. This one is more adapted for large hand. You can grabb it much more easily. I regret only two things:
Trim and functions buttons are really small and control sticks rather short.
Since associated springs are strong, it’s a little bit with these short sticks to have a very pricize flights IMHO.
You can calibrate both gyros and the headless mode. For the headless, select your initial heading then push both stick in lower left position.
For the gyros, install the FQ777 on a flat surface and push both sticks in lower-right position.
As you can see, you can recharge your quad via this external power cable. A very good idea, if you are far from any USB plug.
The internal part of the TX :
A XN297 daughter board is present
Unfortunatly even if the Cheerson CX-10 was written on the main FC, I was not able to bind with any known CX-10 protocols of deviationTX.
This FQ777 flies well, the yaw rate is not too fast not too slow (not proportional with the two speed modes). Funnels and flips are tight and in sport mode it’s rather fast. So no major drawbacks can be noticed in the flying attitude that’s a good point. It’s very similar to CX-10 caracteritics maybe just a little bit more sporty IMHO. After several pirouettes in headless mode, this one is still working correctly especially if you proceed the headless calibration before take off. The “one key return” is also working but don’t expect something very accurate…. The flying duration is around 4min30-5min (without prop guard). The range control was also very good: no problem at least within a radius of 30m (I didn’t go beyond)
For 16 USD, this FQ777 represents a real challenger to CX-10: cheaper, great flyer, transpotable, 8 spare props, prop guard, headless and one key return modes, larger TX so all ingredients to be your new companion.
+ Good and stable flyer
+ Good yaw rate
+ Good flying duration (5min)
+ Good radio range
+ Efficient Headless function (reference “Courselock”)
+ Headless calibration
+ 8 spare props
+ Prop guard
+ Pocket transportation
+ Can be charged via the TX
+ LVC LEDs alarm (around 4mm of flight)
– Short TX sticks
– YAP (Yet Another Protocol but must be very close to the CX-10 “green”, potentially Deviatizable)
– High frequency noise emitted
This quadcopter have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thanks them for this attitude.
You can find it actually for 16 USD at FQ777-124
