I do think it's a swash mix issue, in the model file the elevator swash mix is inverted :
[swash]
type=120
ele_inv=1
ail_mix=50

This maybe the culprit, don't reverse your servos just play with the swash mix settings, in this case get rid of the "ele_inv=1" line.

I don't know how much experience you have with CP helicopter but this video from Finless Bob could help with ccpm setup :

I won't have the time to solder the module before end of next week, and test myself...

That it too bad....

I see on ebay many offers for these modules:

They go for ~ 7USD . are they similar? they all show NRF24L01+ on the IC (along with more numbers).

http://www.ebay.com/itm/NRF24L01-PA-LNA-SMA-Antenna-Wireless-Transceiver-communication-module-2-4G-BR-/151121393024?pt=LH_DefaultDomain_0&hash=item232

or

or would a shielded be better?
Shielded NRF24L01P + PA + Antenna



I would advice with the shield. I owned the last one and it's working perfectly both V2x2 and V9xx protocal

My own module is Besram's shielded module as in your last link. They claim it has nRF24L01P, meaning nRF24L01+. I did not verify this claim - they are VERY compatible with just nRF24L01, the difference is the "plus" support 250kbit/s bit rate and original only 1 and 2Mbit/s. This may or may not be important to you - some protocols use older nRF2401 chips and their bitrate. But as SeByDocKy mentioned it is perfectly suitable for V202 and V922 protocols.

I fixed ele_inv=0 and it seems to be ok. Now I should fixed the curve of control to have a smooth control. But by the way, it's going to the right direction. What's a pitty that I understand almost nothing to all these parameters

Please find attached the modified model file for V922/fbl100 using a modded devo 7E with the nRF24L01+PA chip. This model file is based on a modification of the orignal model HT8-FBL100.

It's working great....
Many thanks to victzh (for compiling the suvsun devo7E branch) and blackmoon for his help

I'm glad it worked.

Now I don't have to rush myself, I'm lazy :D :P

I ordered the shielded module from ebay.

Now I have to wait a few weeks...

Thanks for your help...

Seb you should post you config file in the model config topic, here it will be buried soon.

Hi there isn't a nrf chip that has a flexible antenna so you can push it inside the original antenna hole?
The chip linked has a rigid antenna so you have to cut the tx case.

Is the chip for hisky the same for skyartek? Thanks!

It is not recommended to put two antennas that close to each other...

Ok not inside the same original antenna's hole but there isnt' a way to get a flexible antenna anyway to put it inside the case? Is that module full range, despite of the A7105 module that has a mini antenna?

And what about the HT8. Does it contain a module for the aim?

Victor the FLB 100 is on its way. I need it or the one you bought from HK back as it's the only one I have and I'll need it to test the Devo 7E's we'll be selling. The choice is yours.

Recommended or not, I just bought some antenna coax to replace the connectors that came on the modules I bought, and put all 3 antennas (stock plus 2 modules) into the stock hole. Works great and I haven't had any issues.

@MassiveOverkill - sure, but I still have several problems with it - the one you sent me recently stopped driving one of its motors, so you probably should wait until I get one from HK. I will try to fix the problem - seems to be failed FET.

Also, I noticed the difference in behavior between sunvsuv's code and HT-8 - it sometimes loses the signal for the former and almost never for the latter. I suspect that protocol is not fully reversed - I see that the receiver tries to listen to some addresses I can't see in sunvsuv's code. So it is basically work half done.

I would appreciate if people who tried this code report on their success rate.

Also, if someone has sunvsuv's contact info besides Bitbucket repo's, can they ask him to contact me so we coordinate efforts.

No problem, I have lots of FETs, it's just a matter of finding them - I recently moved ;-) Also, it would help if I knew what FET is it - if I solder better FET it will not fly better, it will skew ;-)

Anyway, work ahead! And thanks for providing me with it, it helps a lot.

I wish I knew. My electronics is novice. If I had more boards I'd try to find out. You've swapped motor plugs to make sure it's not a motor right?

Victor Thanks for your work on this protocol. Here are my results so far.

I have the V922 and a Q-Bot. I was able to bind both to my Devo 7E.

The Q-Bot was easy to bind and seems to fly fine. When setting still at close range... 4ft or less the bind light will go out intermittently. I have not had it drop out while flying even at close range. I am using the transmitter antenna from a WLToys V939 soldered to a nRF24L01P. The antenna is routed horizontally inside the top edge of the Devo 7E.

The V922 flies using SeByDocKy's model config. I did have a hard time getting it to bind the first time. I'm not good enough with the V922 to compare performance to the HT-8 module. I have not seen the V922 bind light drop out like it does on the Q-Bot.

Thanks, Ardy, that helps. I'm still trying to figure out why the light goes off for my Q-BOT.
