I upgraded a APM plane to Pixhawk.
All servos (Hitec) are shaking a little on certain small, random input. Diffrent kinds, and different batches (dual servos for redundancy)

  • and no- it’s not a power problem.

Whan can be done about it ?

  • Yes, I posted something similar on developer-forums, in case a shange in source can fix this.

The cause was two rudder servos that did not like 3.3v PWM, they caused more noise as they went bananas.
