I highly recommend…no, I urge everyone to add more detail to these types of questions. There could be vastly different reasons based on XBOX or PC. I’m finding many of these types of questions are the result of user error, not understanding the complexity of key-binding an axis or controller or something else altogether. So…shooting in the dark…if you have your realism set to ultra, you could damage your engine if managed incorrectly resulting in no engine control. Or something is wrong with the controller bindings for prop/throttle.
