Ah, that is another issue.
Cyclic gain will probably not help there.
This problem can be caused by:
- main shaft or feathering shaft is bent
- some servo is failing and starting to jump (usually elevator)
- subtrims were not configered precisely (less likely). When Subtrim (tuning) is active all servo arms should be in the middle, swashplate at ghe horizontal position and zero degree between main blades.
Stripped it down and rolled main and feathering shafts on a mirror, both are straight. If anything is bent it is main grips or hub but that is unlikely.
Stripped the servo that was harder to move by hand than the others and inspected, cleaned and regreased the gears. It is moving a little more freely now.
Swash perfectly level with blades at 0 pitch, hovers stationary with no drift.
I lowered the main gain down to 45 and the wobbles got way worse so I raised it to 65 and will test again tomorrow.
