I'd do it in AH2. You may need to "set all buttons" so the game sees them. Also, check and make sure the corner views are working. If not you can set those also.
The path to set all buttons is:
esc/setyp/controls/josystick/select joystick.
Look at the center column. It will show your joystick there and under the center column. Are two the two buttons you need to click to activate all the buttons.
When done there, go down one line on the list under the map to:
Stick mapping and you can do the rest of the setup there.
You may also need to make adjustments that you like under settings. No matter what changes you make I'd suggest you finish by calibrating the stick. Make sure you move all controls, including throttle and rudders to their full throws during calibration (besides the stick).
If you want more individualized help I can meet you in the TA and get you setup.
Hope this helps.
