If you have a controller or any type of joystick installed it will automatically have your up down left right controls (arrow keys) switch to that controller. I forgot I had a flight stick plugged in and as soon as I started moving it around the chick moved around. I noticed the joy play selection in the options is blacked out. I think the game is supposed to be played on controller.
If you want to use your Hotas stick to play send it I guess.
