what Allied aircraft are the best in this game?

[gaunt1]

For allied, you mean strictly american or british fighters? If not, then try the La-7. It is maybe the best aircraft in the game, no axis aircraft can match its performance, they are not even close. They cant turn, cant climb and cant run. But keep in mind, La-7 has maybe the least realistic FM, so if it is important for you, forget this plane. If you wish, you can actually turn with a Zero in a La-7!
