Even with a keyboard it will start to do this.:joystick:
Once in the Air you turn to the left and suddenly it keeps pulling left.
It slowly increases over time the amount of pull, fast or slow. Never right.
The only way to fix it is to jerk it right for a long time with the rudder and stick. Then the hud appears off center. but it will slow the effect of the pull to the left.
Update: Just took off and it seems to be fine this version. v1.5.4.55584.141
Pulled left and right it will recenter just fine and follow the heading.
