Ok... always do this: 1. Load other plane at the start of xplane. See if you have you axis assigned there, if not assign them there. 2. Load the Jetstream. 2a. if you are loading the plane with engines stop, the yokes won't move and the pedals. You have to unlock the controls in the right-botton side of the pedestal. putting the lever down. 2b. if you loaded the plane with engines running you should have the controls enabled, so you have to do anything. 3. fly the plane as you like to fly the time you want. 4. When you end it in your case ALWAYS do it with controls NOT LOCKED. Load other plane. Check if you have your axis correct there. quick xplane. in next session in xplane load again other plane, you should have your axis ok.. if you never exit xplane with controls locked and the jetstream loaded.
