When playing the earlier planes, esp. against the Japenese, you will find yourself getting shot at from behind an awful lot. An easy way to avoid this is to suddenly cut back your throttle to almost stall, make your plane pitch forward and then quickly change your throttle to wide open. When you do that make your plane point to the sky. The persuing plane will shoot by you, making you the hunter. This will not work with the 262 and Komets, as they have a better turn radius than most of the slower planes.
