Shaking & unstable flight


I made a mini drone using dji snail engines with ardupilot and pixhawk 2.1.

The problem I couldn’t fly the plane its high responsive to a level it’s impossible to fly.

I lowered PID but it didn’t go well.

People suggested to change dji engines to other type but I seek for your help.



Post a log if you can. Set gains to one quarter of defaults and try autotune.

Hi James,

Did you face this problem before?

Yes. Not with DJI snail, but small, high KV setups need really low gains, and often higher filter values (40 or 50).
