The CH Combat stick uses two hats. Actually one of them, the coolie hat is the only real "hat" of the two. The other one though configured as a hat is actually set up like four buttons, 7 up, 8 down, 9 left, 10 right.
If we had buttons for 9 and 10 we could configure them to our hearts desire, but we don't and I have tried all imaginable configurations in the keymapping utility to get them to work right.
Fortunately I have a CH Pro Throttle and I was able to configure the 9 and 10 positions in it and it works fine now. If you don't have a Pro Throttle there is a program available to allow you to program those positions but unfortunately I can't find it now. It costs about $20 or so and may be available at download.com.
Hope this helps...
