Update: The sim also crashes without having FS_TOOL running…
Its some kind of bug or problem with the Alpha and Bravo that other users have reported aswell.

UPDATE: Also with the AFC Bridge/LED Driver installed the sim crashes when moving the throttle/mixture/prop handles. It’s a know problem others have reported aswell.
