I always shoot worse in the P-51D than I do the P-47. The P-51 is always walking all around the target due to the decreased yaw stability that's present. The P-47 is so stable, its like flying a turret. Of course, I never fly the American rides with combat trim, so that has a lot to do with it. Another is that the P-51 seems to get more stable the faster it goes, so a slow, AH dogfight speeds, the Pony seems incredibly unstable, whereas the Jug, for comparison, keeps the nose where you point it. No quantitative evidence to prove these theories, just feel in game...
