just some idea here, i have the 8 way hat set for views, i have trakir so i mostly use it in gv's. the red button on top is to select secondary weapon, hard to reach, so i figure sec weapon is not used that often.
left 4 way stick has my map (up), expand text (right), level flight (left), angle flight (down).
right 4 way has wep(right), open bomb bay doors (left), and flaps up/down.
pinky switch fires secondary (usefull in il2's, 303's dont kill tanks)
botton right side is to fire primary (usefull to fire 303's few rounds mg's to make airplanes nervous)
trigger fire all weapons.
"thumb" 4 way: talk range(forward), chanel (back), right/left are empty, coudnt figure out what else to add there.
rest of buttons I use are set up in my throttle, such as check six, pause/center trakir, zoom func, zoom in/out, look up.
I have different set up for gv's.
hope this helps or at least dont confuse you

. I have set up my throttle/stick/pedals (pedals have wheel breaks) so i dont have to move hands away from keyboard other than to type or do seldom used things such as gear up/down, etc.
