Hello there,
I am a noob scale-type flyer with a OMP M4 max and Spirit GT. Tailservo OMP 3515T
I love lower revs (normal 1800 iup1 1900 iup2 2000).
I put some love and time in the setup process of the Spirit, and all is fine, but one thing is persistent:
there still is quite some tail wagging, but only when hovering.
With 1800RPM it is not much (acceptable), but when switching to higher revs it gets worse. The frequency and the amplitude of the wagging increase.
Tail servo is a mini and stays cool, cyclic servos are micros and get quite hot (45-50°C) even when hovering and no 3D-stuff (which I can't).
I checked if the rudder delay is correct and tested values from 2 up to 20, didn't help. My servo is sadly not in the list.
I changed the tail servo frequency from 560 to 200, no effect.
I played with gyro and pirouette consistency values.
I checked that the tail mechanics is smooth, and it is really smooth, no stick slip or high forces needed.
I checked the timing of the main blades, which is fine.
When spooling up the heli, there is one short moment when it is shaking slightly (@ ~1000rpm), then it is smooth and the vibration analysis also says that all is good.
My settings are:
Rudder rotation speed 11
Rudder Delay 5
Gyro gain 85%
Pirouette Cons 161
Rudder dynamics 6
Cyclic gain 55%
cyclic rot. rate 10,5
cyclic feed forward 5
elevator filter 4
Flystyle 6
Can you help me where the wagging can come from and how to stop it? I would like to change to revs higher than 1800, but not with this current behaviour.
Thanks, Chris
