Joystick Rudder issue

I use a M$ Precision Pro 2 joystick to play FS2002. The rudder control of the joystick works well for all my small aircraft (Cesnas and Beech and Mooney), but not the heavies (Boeings and Airbuses). I've already tried "rebuilding" my joystick settings for FS but it didn't work. Any ideas on what I can do?It works fine when I'm taxing the aircraft but not in flight.Cheers!
