Ok, try my build, it should be fine.

There's something weird tho, can you tell when does the byte to the left of FF in the full throttle capture switch from 0A to 0E ?
(first number of the 2nd line) or maybe that's just a glitch of the picture due to slow lcd refresh rate.

While you are dumping again, you might as well check the other buttons for us. According to jjrc ads the drone features return to home, headless, lights flip and one button start and landing. All those features should be captured for us.

I will be happy to check the other buttons for you send the dumps soon. this drone has all of the buttons you mentioned except for the one button takeoff landing and LED control feature. It is a mistake in the advertisement. It does have headless, return to home, and the flip. I haven't had a chance to even try your test build because I just came home from work at 2 a.m. but I am excited to try I will do it shortly and also send the info on remaining buttons. Thank you for your help. Chris

Here are the last three functions you need. Headless, return home, and flip.

Headless



Return home



Flipmode



That is the extent of the functionality. Please let me know if there's anything I can do to help you complete the test build. Thank you very much. Chris

I think your last 3 captures are wrong (no extra flags), you probably need to apply some throttle to enable those features.

Headless



Return home

Ok good, seems the 0A -> 0E transition that I didn't understand is flip mode.
Try the test build, if it works I'll update it ;)

Ok, you mean it's 0E only at full throttle (FF), nothing to do with flip mode ?
On the 2nd picture, seems throttle is full (FF) but the previous byte is 12, not 0E, is it only when RTH is enabled ?

The drone binds. Response to throttle and elevator. However it flips on its own uncontrollably. I tried switches in each position. Still flips uncontrollably.
