If you see unexpected rapid servo movement then your PID gains
may be too high; this may
cause the servos to overheat.
11.
The
PTCH2SRV_RLL
parameter is used to keep the nose level during turns.
If the aircraft gains height during turns then you need to reduce
PTCH2SRV_RLL
by small
increments of 0.05. If the aircraft immediately descends during turns, then increase the
PTCH2SRV_RLL
by small increments of 0.01.
12.
If you are not able to achieve smooth pitch reactions, then recheck AHRS level configurations
and/or pitch axis orientation. A more detailed explanation can be found here:
