Whenever I put the throttle up on any a/c, the plane will move to the left, and if I try to correct it, it will turn again. I have tried the neutralize the rudder and aeilron, but it still does it. Also, on auto pilot, the plane will ALWAYS be tilting to the left. Please help me!

Hello :)Have you tried calibrating your joystick?I had similar problems and after a recalibration it was all sorted out.

...Or make sure that when you move the throttle, both engines are spooling up and not just one.Jeff USAF
