XP11 is not consistent with how it behaves and problems are not always easily found online, there also seems to be a 'hidden knowledge' that is assumed with arrogance on forums as if not knowing makes you stupid and those who do superior. Other problems include scenery downloads having constant error messages and need to be run numerous times to prevent random in game messages, releasing the brake sometimes doesn't work, CTR M can be tricky, the engine may just stop if the throttle is reduced. Solution is to reset the flight.
