I have;
First trigger click primary guns,
Second trigger click all guns,
Top hat switch view shift,
Lower trigger switch snap views,
Pinky trigger to look up,
'Fire' To secondary,
A to flaps up,
B to flaps down,
C to secondary weapon select,
and the switches to select gunner positions...
on the throttle;
E to engine,
the rotary thing around E to aileron trim,
D to gear,
the slider under D to elevator trim,
I to WEP toggle,
The little silver button next to the blue thing to channel vox,
and lots of little functions on the hat on the throttle,
the rolly wheel shifts the amount of zoom and pressing the wheel brings up the clipboard.
