I think you missed my point. It just does not sound like a real airplane in certain situations, in my opinion. But, I know very little. It is almost as if the game, instead of letting you hear the engine from 1.5 to 800, takes those sounds and applies it at 800 at double speed until it passes. Almost like the sound is at 2x speed. It makes for a very unpleasant experience. Given the popularity of the P-51 in the MA, I had to resort to default. I eagerly await a patch!
