I programmed mine for
24. I use the "mouse hat" thingie on the throttle, up and down shift the view accordingly, and left and right zoom out and in. That way, in bomber sight mode, I can zoom in while at the same time looking down at my target.
I use the pinkie switch for switching zoom on or off.
I use rotaries for trimming. That's what they're made for, and I have a thick skull and wanted to use them for that purpose, so I manage.

Hat on the back of the throttle controls level autopilot, gear, displays clipboard and damage. D button is for talking, "mouse" button for voice commands to GameCommander (yelling "17 front!" takes less time than deciding which key will send me to front gunner on the B17, and frees my other hats for something else).
BTW I think you don't have the "mouse" button on the X45. Well, I think that's the button most likely to fail. Mine is beginning to give me trouble.
I really like my stick, but it really pisses me off that Saitek won't release the Windows 2000/XP software anytime soon.
