Mini-Review

WLtoys Q242G (Under construction)





INTRODUCTION

Here is a new mini builtin FPV quadcopter from WLtoys, the V242G. One more time, a new competitor to the very popular to Hubsan H107D. The FPV part is based on a 5.8G system, a 4".3 builtin and HDready 720p cam recorder. The main marketting argument is its price versus the Hubsan model.



BOX CONTENT



+ 1 x WLtoys Q242G (with a 1S 400Ah LiPo with JST XH connector)
+ 1 x Transmitter (using 1S 500mAh LiPo with JST connector)
+ 1 x 500mAh 1S cell with JST connector
+ 1 x USB charging cable
+ 4 x Spare props (2 CW, 2 CCW)
+ 1 x 4GB microSD card
+ 1 x USB microSD card reader


OVERVIEW


-Front view






The camera lens module is unfortunatly in M6 format (now very popular).


As you may already know, there is no wider lens in such format.

-Side view



-Rear view




The battery bay welcomes the new "DJI styled" battery

On the bottom side, you can find the 5.8G VTX-cam combo



-Upper view



-Bottom view

The linear 5.8G antenna (directly soldered on the VTX side)



Two small LEDS on rear.... and one associated with the camera-FPV module



-Weight




A total weight of 52.5g



Thanks to its 8.5mmx20mm motors, this weight means a very good ratio thrust/weight for the Q242G.

Motors

8.5x20mm coreless brushed motors




LiPo

A 1S 400mah with a JST-XH connector.





Be aware, polarities are inverted.

The locking system is IMHO fragile and will break fast versus time



It won't be a big drama since the LiPo is attached mainly via the JST-XH connector.

Camera module

A 2Mpx HD fiming in 720p format. The lens mount is in M6 format



Unfortunatly, the camera module is now directy soldered to the VTX-DVR PCB. No more ribbon calbe so no more possibility to install a 808#16 lens D
lens+sensor as former model

Disassembling

Pretty easy to access to internal part: just remove 4 screws, unclip the four locker at arms extremities and remove props





The XN297 is here. Unfortunatly, actually I was not able to bind to any existing XN297 protocol (even the Q282).








Transmitter

A large gamepad style is introduced. You can grab it easily in hands, I like.


Two double toggle buttons are installed on the left and right shoulder respectively. For the left one, if you press on the left side, you can cycle between the three speed modes. The Yaw command is not proportional to speed modes. I didn't feel a big difference in pitch and roll rates between the intermediate and expert mode. The export mode could offer a little bit faster forward. The right side if the switch engages flips. The right shoulder toggle button is linked to the camera control: the left one turn on/off camera recording, the right to take a photo. To engage the headless mode, you have click on the left command stick and the one key return to the right command stick. Finally, the gyros calibration is done by pressing both stick in lower-right position.




No black/blues screen... It's a good news but the screen is brillant..



The angle of vision and brightness are improved versus the former generation of WLtoys 4".3 screen (at least)





The Vfreq is locked to 5645Mhz (E4 freq in Boscam band)



The internal shows a half-plan 5.8G antenna directly soldered on the VRX while the 2.4G antenna is foiled






TX pinout



FIRST USAGE

WLtoys Q242G first demo flight (Courtesy Banggood) (7 min 11 sec)


Super stable quadcopter, relatively sporty. Stable videos recorded but with very narrow field of view. A little frame rate drop can be observed as soon as recording is turned on. Average flight durations is 5min with recording turned on.


WLtoys Q242G new demo flight (Courtesy Banggood) (6 min 18 sec)


I noticed than after a fast forward, the quad have difficulties to autolevelling and can loose altitude. The FPV minitor is much more visible in daylight conditions, it's a good news.

CONCLUSIONS

This Q242G machine a good beginner FPV plateform. It offers stable and Jellofree 720m videos. The FPV signal is strong and the FPV monitor have been improved. The radio link give you a good 60-70m of control range. The machine is more adapted to practice FPV in relatatively open area, the limited FOV don't allow you to fly fast nearby trees for example. I regret the non easy possibility to install a lens with a wider FOV. The main question: is this Q242 better than the Hubsan H107D ?. No so much more.... The Q242 offer a better FPV part (stronger signal and more visible FPV monitor) but with the H107D you can install more easily a wider lens.

UNBOXING

WLtoys Q242G Unboxing and quick testing (Courtesy Banggood) (14 min 39 sec)


PROS

+ Good flyer
+ Relatively punchy quad (thx to its 52.6g)
+ Speed modes well parametrized
+ HD ready cam (720p)
+ Stable videos, jellofree
+ Relatively good 4.3" FPV monitor with improved brightness and angle of vision
+ 500mAh TX LiPo
+ Cheaper than the Hubsan H107D (86USD vs 129USD)


CONS

- Can be instable during a hard turn after a fast forward
- No Vfreq selection (fixed to E4=5645Mhz)
- No TX 5.8G antenna connector
- Battery casing
- Inverted JST-XH polarities connector
- Lens slightly oriented to the ground
- Narrow FOV (for M6 lens mount)
- No more compatible with the 808#16 lens D combo
- YAP (Yet Another Protocol)

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 86USD at http://www.banggood.com/WLtoys-Q242G-Mini-5_8G-FPV-With-2_0MP-Camera-2_4G-4CH-6Axis-RC-Quadcopter-RTF-p-1010713.html

Much better than the 282, which has 10 to 15 metres. Odd to see such bug differences in the same brand.

Can you check with the Q282 if you have a soldered ribbon cable between the camera sensor and the video board ?

GearBest sent me one. I was only getting a control range out to about 30 meters, while it had a good FPV signal much further than that. Because of the limited control range, this FPV quad would be best suited for indoor FPV flying. It seems to be very stable, and that would also help indoors. And besides, it's Winter, and most people will be flying indoors for the next few months anyways Here's my thoughts on it.

And here's a flight test demonstration.
