I currently have the cowl flaps assigned to the up (open) and down (close) positions of one button on my throttle quadrant. But as far as the game is concerned, those are separate buttons anyway. I have the CH Products yoke that comes with three levers (for throttle, prop, and mixture), but since I also have the throttle quadrant, I would like to assign the cowl flaps to one of the levers on the yoke, but this does not appear to be possible. But then I remembered that the control manager software that comes with the CH Products stuff is supposed to allow you to make assignments that would otherwise not be possible with the normal USB - game interface.
So I installed it.
Oops...
It completely re-wrote all my assignments! And I had them all setup the way I liked em. So I've been muttering cuss words this afternoon while I re-built my assignments for the two-engine and four-engine configurations, for FS9 and FSX.
When I get done with that I'll see what the fancy control manager program can do.
