Sorry to resurrect an old thread, but I have the same question as well.
I discovered I can add a modifier switch and use my hat switch for other things as well.
Right now I have my hat switch set for viewing, trim, and coolie. (Now if I can only figure out what a coolie is.)
I would like to see how you guys that use this stick mapped your buttons. Any advice is helpful.
P.S. TrackIR will be here Wednesday, so I need to figure out what to map to the hat switch instead of view controls.
