the problem is not that the aircraft is losing control but the ailerons only turn on direction, even if I am turning them up or down. for example, if I am trying to turn up, the ailerons would instead steer the aircraft down. after that if I turn down, the ailerons still turn the aircraft down. the aircraft stays completely stable the whole time. also it might help to mention that this happens on any plane, even each of the stock pre-loaded planes that come with the game.
sorry if that doesn't make sense, I'm really bad at explaining things
