Microsoft Force Feedback 2 Issues!

[ATAG_Snapper]

I can only speak for the aircraft I fly, the Spitfires and the Hurricanes, which require constant elevator & rudder trim adjustments with any change in throttle, pitch, attitude (climb, dive, level, turn), undercarriage, flaps, etc. to avoid the situation you describe.

I can only suggest you check your joystick defection values in Options/Controls/Axis to ensure your MSFFFB2 is calibrated OK for this sim.
