Uh Oh. Did you to program any unused buttons or previously use the stick elsewhere, such as with FSX?. I have the same joystick and had similar problems. The cure was to reset the stick to
default mode as mentioned above. Unfortunately, programming the unused buttons slaves the rudder and nose gear to the throttle. Using chase view you can see it happen: Advancing throttle turns rudder and nose gear right, and reducing it turns both left. Resetting puts stick in default mode, where elevator, aileron, rudder, trim, flaps, throttle ,brakes ,view, using hat switch, and toe brakes using buttons 11 & 12 work fine. Tried re-coding the default settings in the program for gear, etc., but that caused the problem to happen from start, and be unrecoverable by resetting. Problem is an unfortnate idiosyncrasy of the 3D Pro.
