I follow heli tuning guide, and tuning ff and yaw is perfect.
Also I activated the HNOTCH to 17Hz (1000Rpm rotor governor) with 1st, 2nd and 4th harmonic.
Vibe is ok.
When I pass to roll pitch pid tuning, I can’t grow the D term above 0,001…
I see directly vibrations appearing.
and I always have 1°AMPLITUDE oscillations on roll / pitch.
So, to be able to put up D term, do I need to down standard 4,5 ANG PIT/RLL P ?
there is another solutions?
Also due to kerosene movement, and with ILMI R/P to zero, machine cannot stay perfectly level in stabilise.
but in the logs I can see I term on PIDR and PIDP … Why? it should be to 0 level du to ilmi 0 in hover flight no ?
I think to put ilmi to 0,1 to get this issue off.
