Is it normal that the servos jitter if the ACM is in fly mode?
The jitter can not come from electrical noise, because there is no jitter at all as long as I am in CLI mode and e.g. setting up the board with the "heli" commmand.
In my opinion it is triggered by the noise of the gyros and accelleration sensors, so the ACM wants to correct by swashplate movements, which leads to the servo jitter.
Do you have the same effect or are all your servos "quiet" as long as the board is not moved?
Would it help to solder the filter on the oil pan?
