Fixed wing plane flying oscillation problem

ArduPlane
1

I take off in auto mode with a fixed wing aircraft in the gazebo and I fly at a fixed altitude, but I constantly fly by oscillating on the pitch axis. This problem does not occur with stabilized and FBWA.

Hello @Tahir_Can_Kozan, going to need some more specifics before we can help:

  • Gazebo and ArduPilot version?
  • Which model and parameters?
