Time ago I did find this interesting camera on BangGood ... at least it was looking interesting

42$ shipped - 5% discount (bestBG / goodBG) ... so 40$ for a shipped full HD cam, was looking interesing

I was hoping to find the Mobius RC CAM format with G1W quality ... a very good mix, Novatek chips on G1W and Mobius does the same 1080P30 and 720P60 and both have Video out too ... a feature that was looking available from the included connector.

Instead of Novatek good encoder chip, WLtoys decide to put a dummy CPU that does only bits moving, from JPEG data from the CMOS sensor module back to the microSD .... very dummy indeed to have 720p60fps and MJPEG ... they could have used 720P30fps and higher quality instead ... anyhow.

This camera is a failure under all the possible aspects ... so ... let say ... my lost ... is your win ... so you may avoid to buy a junky camera.



PS: For budget, in the RC world, the best cam are still Mobius and TOPCAM ... DIY people may modify G1W for fit into a RC bird too.

Since I got this JD-392 and it is a very nice kids grade aerial video quadcopter ... I decided to make a mini review ... with my "classic" garden outdoor fly

I think this cheap RTF is a perfect Xmas gift ... and in BNF mode is a perfect self gift for DIY v2x2 or for who has already a v2x2 TX



ps: If you like this video, please thumbs up on YouTube and maybe subscribe too ... if you don't ... well ... sorry for have wasted few minutes of your time

Wltoys v272 - Amazing Hand Launch + Catch & Crash + Fix - With Slow motions (2 min 20 sec)

v272 in Actions ;-)


Here is the v2x2 TX module.

Code is based on:
- PhracturedBlue / Deviation ->
- Midelic port to Arduino ->
- e_lm_70 hack and port to ATmega48 arduined

Support functions:
- Auto Bind at start up (always)
- Read PPM input (8ch support, 6ch used)
- Send Throttle, Aileron, Pitch and Roll + Flags
- Support Flags: Bind + LED (CH5) + FLIP (CH6)

Needed hardware:
- 5V source (actually anything between 5.5 to 3.3 should do the job)
- (3.6$) I2C to SPI NRF24 adapter ->
- (1.1$) NRF24L01 module ->
- (5.3$) NRF24 PA module ->

Support hardware:
- PPM generator (I use FrSky D4R ... so FrSky TX can be converted in v2x2 RX)
- USBasp programmer
- Jumpers cables

Support software:
- eXtreme Burner ->

Optional hardware (for run the v2x2 RX simulator, for trim the TX, and check functionality ) ->
- Arduino Nano
- 2nd NRF24
- NRF24 Adapter - >
