On my G940, I never bothered to program the trim wheels for Aces High. Personally I don't like how the game handles a trimmed axis, but mostly because I like the 'auto set' trim function better (the period key.. of course I have it programmed to my stick as well). I do have the R1 trim on the throttle set for RPM though.
What I can program without the software I have programmed through Aces High (and left unprogrammed in the software) but some things had to be done through the software like macros, shifted commands, etc. I guess I'll give you my assignments below.
I should add that Logitech is about to release a new firmware that greatly improves the stick's accuracy (by greatly reducing the
REVERSAL BUG). I currently use a beta version of the firmware and it is a HUGE improvement, but unfortunately I am not allowed to share it but it's supposed to be out by the end of the year. The Reversal Bug still exists in all of the other axes, but hopefully that will be the next thing they fix.
