Pete,
I seem to have a similar issue on the Saitek X52 throttle. Would you be able to tell what I need to delete so I can get my throttle to work? Currently both my disc install version as well as FSX:SE are having the same issue. I move the controller to full throttle then the throttles in the aircraft bounce from full to about 1/4 throttle and then will bounce back. Thus leaving me with a start stop type of flying or will not really move; move the controller to full throttle and the in aircraft throttle will go all the way back to idle and stay there. I have tried this with several different aircraft and get one of these responses to the throttles.
Thanks
Jack
