TEST: FQ777-124 Pocket Drone

null

INTRODUCTION

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.

BOX CONTENT

null

+ 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)

null

In comparaison with the WLtoys V676

null

Body guard

null

You don’t need to remove props to install it.

8 spare props are provided. It’s a really good point

null

12.3g standalone so 0.3g more than the CX-10 and the exact same weight tnan the CX-10A

null

With the landing gear added, the extra weight is almost 0

null

Disassembling

4 screws to remove to splut in 2 parts the canopy

null

The LiPo is a 1S 100mAh directly soldered on the power connector pads.

null

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

Motors are identical to the cheerson CX-10 and for most nanoquadcopter, some tiny 6mmx12mm coreless model.

Transmitter

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.

null

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.

FIRST USAGE

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)

CONCLUSIONS

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.

UNBOXING

PROS

+ 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)
+ Cheap

CONS

– 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

    Please post TX captures to the CX-10 protocol dev thread, I’ll take a look 🙂

      Ok 🙂 …. I got 5 différents models actually to capture using the XN297 🙁 …
      -MJX X600 (should work with X800, X900)
      -FQ777
      -Eachine H7
      -Eachine H8mini
      -W609

      and there is a new nRF24L01 clone (HS6200) in the Fenico F4-4V

  • admin says:

    Strange for me seems to work perfectly 🙁 …. I have to check. Thx for reporting

  • admin says:

    Thanks a lot 🙂

    Just received mine today from Banggood. Absolute magic! I find it flies better and smoother with the propguards fitted. Without, it is very sensitive and jittery. In the envelope with the spare props, were two “thumb sticks” to replace the round control knobs. They stand 13mm above the controller case and make flying much more comfortable and precise.

    I got mine a few months ago, and it worked perfectly. Then one day i notices that the bottom right motor seemed to be getting stuck on something. I checked multiple times, and there was no hair or anything stuck in it. That issue seemed to have subsided, but recently, after it finishes charging, i go to fly it, and it takes about 30 seconds to trim it but then the battery runs out and it doesn’t fly anymore. Also, the top right LED only sometimes works.

    • SeByDocKy says:

      Sound you machine was already pretty bad out of the box. For the short flight duration, I guess the LiPo is damaged (maybe you flew over the LVC limit previously ?). In general,
      I am using a real charger coz in practice all the USB charger are pretty bad (overvoltage in practice).

    hi
    when i used my pocket drone first time everything was ok, i tried to have fun, but i always charge it via iPhone charger i mean not with usb. than now its not ascending, its’ just one side is ascending a little and other side is on the ground.
    please help me that how can i solve this problem. i did calibration every time, trimming settings but no result. do you mind is this about charging method or what ?

    • SeByDocKy says:

      I guess your internal LiPo is now damaged. 1S cheap LiPo have very fragile and a good charger is very important to not damaged them…. I guess you will need to buy a new LiPo. I strongly advise if you continue in this hobby to buy a real and more Professional charger which control perfectly the charging process. I guess your phone charger was not really adapted for your LiPo.
