One of the problems I experienced was after being shot down or crashing. When prompted to press "X" to continue I was somehow prevented from doing such. The "X" button is on the throttle controller but would not be read by my PS3. Finally, I discovered that if I had to have the throttle in the upright (90%) position It would register. I do not know if you have run across this but it frustrated me some what. I was also using a Custom set up for my controller.
