I was talking about cockpit view as well. My X52 has a thumb mouse on it which works fine for this but I still can't get anything more than FOV90.

WOP has one too. Although I use my right hand on my joystick and use my left hand on my mouse to swivel my head, with the left and right mouse button functioning and zoom in/zoom out.

For the record, it took me a really long time to be able to multitask this way with my left hand on the mouse... ;)

I do something similar, except instead of mouse buttons to zoom in/out, I use the hat switch (right hand) only for zoom. Press forward (0 deg) with thumb to zoom in, pull sideways (90) for "normal", and pull backwards (180) for wide view. I can use my mouse to pan, left finger for mouse button to lean left/right, right tumb to zoom in/out, and right index finger to shoot all at the same time. Plus using rudder pedals, I'm getting exercise while playing Il-2 :D

.

I would of used the hat but the heard jerking to look at the panels (not a smooth movement) made it impossible to track enemies in simulator. So I use the hat to issue squad orders since there are 4 so it seemed to match nicely :)
