I currently use the Saitek X52 as my joystick and throttle. There is one game-breaking problem I've been having. Sometimes, out of the blue, the joystick goes off center. When this happens, when I put my joystick to the neutral position, instead if maintaining steady flight, my plane rolls. I know this is my joystick because in my su-25 there is a line on the dashboard which lines up with a line on the joystick when the joystick is neutral. However, when I put my joystick to neutral, the lines don'y line up.
