I have my KEYPAD_ASTERICK and KEYPAD_MINUS set to select Stick mode 2 and 3 respectively, which I use for mapped bomber gun positions.
While in a fighter or bomber, if I've selected stick mode 2 or 3, my head position is off center relative to the default head position, and none of the head movement keys work. My current work-a-round after jumping to the gun position is to toggle Stick mode 1 or 4, and then push the hat in any direction which returns me to the proper head position for aiming and firing the guns.
I haven't tried it in a GV to see if it works properly in mode 2.
