Haven't tried the game. However, I played others EA Star Wars Battlefront games (2000+ hours), I'm pretty darn good pilot even though flying mechanics are not supported by XIM, however ST works decent for aiming whatever is on your field of view... BUT.
The issue is: turning, if the game uses the right stick (our mouse) to turn is a big issue for XIM because you will need an analog input to turn, meaning move the stick to the right and keep it pegged to the right, you will keep turning to the right; if you don't push it all the way it will slow down the turn speed and keep turning.
On XIM the right stick is our mouse, this means that in order to keep turning to a direction you need to swipe to that direction until the mouse pad runs out, pick it up, put it down and keep swiping, over and over, combing your mouse pad and in-game you don't have a smooth turn, many hiccups.
XIM give us a work around called Turn Assist, when you press or hold that button, you will keep turning to the direction towards the direction the mouse is leading, you can use the mouse to aim again once the Turn Assist button is disengaged.
Caveats: no way to control/regulate you turn speed precisely, dog fighting is way harder than using an analog stick.
As I said it before, is not unplayable and I'm not bragging I'm pretty darn good pilot but it took me hours to figured and master the controllers, using turn assist. I'm so used to it, when I play on PC I use the XIM to flying because the in-game mouse mechanics for flying are dreadful.
In short, not sure if XIM team consider to work in a ST for a game that can be like a driving game.
Flying games/simulator are meant for analog sticks the same way steering wheels are meant for driving games and FPS are meant for mouse and keyboard. Mainly I don't know if they are capable of training a ST for it, so I going to keep my expectations low.
