Sorry to revive an older thread, but I also had the same issue.
Doing as mentioned definately worked and allows the throttle to work, but also had to go to the responses tab and invert it as FOT was behaving like FCT ...
One question I did want to ask you though, how do you find it for flying within ROF?
I thought it was just me sucking at flying, but am wondering if the X-45 is not quite as accurate, especially for lining up for ground attacks. This is the main time I see myself "chasing the ball" to line up straffing runs.
Actually, even in A2A I do quite a lot of wandering the sights when trying to get a clean shot.
I thought it was just me, but wondering if you are experiencing similar ?I feel like George of the Jungle....
