do you have to controls hooked up to pitch and role (2 yokes and or Sticks) if so only have one assigned, also try calibrating your control yoke or stick and if that doesn't work go to the setup page on xplane 11 and look at the little blue dial assigned to pitch and roll and see if it is your joystick that is making it move or if it is just something wrong with xplane, if something is wrong with xplane contact them and if your controller contact them, best hopes Lawson Laslo
