Unstable quadcopter with Naza M V2

[quadcopter88]

Hi everyone,

I've just built a custom quadcopter but having a few stability issues:


Have calibrated ESC as well as the IMU. The quadcopter takes off without issue in GPS and Atti mode. It hovers initially really well (no issue at all) then begins to become unstable.

I've been playing with the gains which seems to improve it on and off, but still having significant instability after 30 seconds of flight. It responds to controls without too much issue but seems to be when its in a hover that it gets shaky.

Any ideas???

Cheers

I would say that it wasn't flying right from the moment you took off and that it looks like a gain issue. What gains have you tried and what are they on now?

I've tried very low gains Roll/Pitch 90/90, default 125/125, and high 160/160. It made some difference but probably not enough to solve the problem altogether...

I would go higher. Start at 160 and go up 10 each time. I think you will find it sorts itself out. If you start to see quick oscillations then you have gone too far and need to back off by about 20.
