Plucking of actuators in stabilized mode

Hi,
after some tests (mentioned Auto-G2 gyrocopter with PX4 autopilot) we have observed a problem that the autopilot plucks with actuators (servos). We are observing this behaviour especially after changing setpoint range parameters.

  • roll: ± 25 deg
  • pitch: 20 - -15 deg
  • airspeed: min: 10, cruise: 15, max: 20

It is happening mainly when the aircraft is on the ground. When someone takes it to hand, it stops (or amplitude of these movements is significantly smaller).

Is this behaviour normal? Or is there any solution for this problem?
