The Cheerson CX-30W is a cheap micro WIFI quadcopter ... it cost less then 50$ shipped.

But it is a total disaster.

WIFI both for VIDEO and RC is terrible
FPV over WIFI is impossible ... low FPS and almost 1 second of video delay.

Using over standard 2.4G TX ... range is very poor, both with SH6043 TX and even worst with Cheerson CX-30 TX ... only 20m with Cheerson TX ... 30m range with SH6043

All in all .. it is a cheap micro copter ... but a waste of money

Here is the video "proof"

Cheerson CX-30 WIFI - Quick Review and Outdoor fly with PiP onboard video (11 min 21 sec)


PS: After CX-10, now CX-30W ... two bad products from Cheerson ... what is strange is that Cheerson is looking to have a decent reputation here on RCG ...

PPS: For make a decent on board video, I did add: "Hubsan X4 H107C RC Quadcopter Spare Parts Camera Module 2MP" ... this is a nice little cam, even if it is MJPEG video quality is decent ... possibly the best cam for micro copter ... but it has not AV Video out ... so ... not expandable to FPV ... 25$ for this cam alone is also a bit "expensive" ... in theory JJRC H8C cost 10$ less and has 720p ... but I did not want to "gamble"

It is quite a while since I had the for SJ1000, at the time SJCAM was not even advertising neither their brand nor their model name ... still ... TECHMOAN discover this little action cam ... the first sub 100$ 1080P 30fps H264 with great video. That was over 1 year ago ... and I was lucky to be the first to put the SJ1000 on the air short after I fix the jello issues and this SJ1000 was making really nice videos : jello free video here

Short after we had Mobius, and this has been since then the best camera to put on an RC bird, at least the best for the price. Mobius did put on shame the Boscam HD19, and as well for RC usage Mobius was better then SJ1000

Clearly GoPro was always, and still it is on his own league ... with the best quality, and the most featured (they have WIFI support since "ages") ... but it come at price.

I recently got the SJ4000 WIFI, the original model from SJCAM (since day one there has been clones of SJ action cam ) ... and finally ... I think the "reign" of Mobius is over ... or at least is weaker ... finally a new cheap action cam is doing better video and has more functions too.

GoPro for factor is a good plus for my book .. since it allows to use all the RC gimbal and camera mounts available ... WIFI and LCD is a nice to have, but nothing really needed for RC usage ... mainly the video quality: sharp picture and accurate colors ... is what make this SJ4000 wifi better then Mobius

Here is the prove of it

Note: Only 86$ shipped from GearBest.Com : http://www.gearbest.com/action-cameras/pp_81588.html , using the discount CODE: SJCAMRX ... this is an incredible price .. possibly the best on the net

Hi,

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

http://www.banggood.com/WLtoys-1080P...-p-943813.html

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.

Hi,

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

v272 in Actions ;-)


Hi,

Here is the v2x2 TX module.

Code is based on:
- PhracturedBlue / Deviation -> https://bitbucket.org/PhracturedBlue...1.c?at=default
- Midelic port to Arduino -> http://www.rcgroups.com/forums/showthread.php?t=2165676
- 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$) I2C to SPI NRF24 adapter -> http://www.ebay.com/itm/NRF24L01-Wir...-/370895866980
- (1.1$) NRF24L01 module -> http://www.ebay.com/itm/High-Quality...-/201060112736
or
- (5.3$) NRF24 PA module -> http://www.ebay.com/itm/NRF24L01-PA-...-/131038716224



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 -> http://extremeelectronics.co.in/avr-...r-programmers/

Optional hardware (for run the v2x2 RX simulator, for trim the TX, and check functionality ) -> https://github.com/execuc/v202-receiver
- Arduino Nano
- 2nd NRF24
- NRF24 Adapter - > http://www.ebay.com/itm/New-Socket-A...-/261503131763
