I have finished my setup, made some changes to my previous installation and after my APM2.6 arm procedure I can see a constant yaw drift. I tried to Maximize or Minimize the Transmitter trims settings but nothing hapend. I have also tried to go through the setup, calibrate my compass and my accelerometer but nothing there too. Does anyone have any idea, how to solve this issue? I did not try to fly like this but I am sure that it will spin around like a UFO xd Pitch and Roll are working just fine.
