Pitch and Roll drift until it converge

Hi there,

I have a problem with my variable pitch quad. And I couldn’t find the reason why my quad is drifting away even it is on a flat ground without any movements. Since it is controlled through the pitch angle, wrong control output make it almost impossible to fly with. Especially I don’t understand why roll and pitch drift in the actuator_control0 topic until it converge.


Can someone give a hint, in which direction i should search for?
Thanks a lot

Is it reporting correctly? land_detector status.

Hi @dagar
yes the land detector is running.

Update: solved by considering the PID parameter in the mc_pos_control.
