I think the problem source is different, thank you for the guys/gals that astutely state physical properties of airflow, but in my case it was exactly what Zack was talking about. The aircraft violently rolled left upon game start. I managed to isolate all my other inputs, gradually turning them on, and finally I am able to maintain a steady flight. Essentially:- 1. Disconnect all usb flight controls so that you are keyboard/mouse only. See if you can fly. 2. Gradually bring on board only the flight controls you need, ie Joystick/Throttle/Rudder. 3. If all is good, then bring in your next level devices (I run 2 MFDs in addition). I think in my case, it was either my Driving Wheel (Logitech G27 or the joypad) that was adding additional bias feedback. By this stage, the computer naturally reset the default input levels and I am able to fly normally. Hope this helps.
