Umm. The reality is that if a planes flys too fast, it ACTUALLY begins to "wobble manacally", as shock waves begin to form over the control surfaces. It's likely you never even SEEN an airplane let alone ever flown one if your trying to take the piss out of X-Planes flight model. Back to Crimson Skies for you pal. You won't get an F22 to be stable at supersonic speeds down on the deck. Just ain't gonna happen.
