Boo,
not a bad idea, just a few thoughts:
-there arent as many post-war prop fighters. They could be added as a separate arena (not to mix them with the classic WW2 planes). Or, only enable them in the DA.
-dont add jet fighters please
-no bombers please, just dogfight
F7F instead of the F9F
P-38K (or whatever the Merlin-equipped version called)
Hughes XF-11
Twin Mustang maybe
there was a developement of the Jug equipped by a big Chrysler in-line engine, XP-72 maybe, im not sure
that japaneese delta pusher wasnt as an über one, but a predecessor of a planned jet aircraft.
Ta-152C
Fw-190 D-13
2000Hp 109K (better fuel)
Supermarine Spiteful
