Stay above everyone. When you're not above them, make sure you're going fast enough that nobody can get a gunshot.
The only way to survive in an f4u4 is to keep your plane where everyone nearby can't keep thier nose pointed at you. The exception is, a dive to the deck(ONLY if the deck is at sea level, above 1000ft a dive to the deck is suicide) should suffice for running to a safe base.
If you don't like being an altmonkey, the only perk planes worth using are the f4u1c, and the 262.
This is the huge problem with the perk system, specificly the planes which don't possess the performance to be untouchable, like the 262 or tempest. The ta152, spit14, and f4u4 SHOULD be perked, and thier prices are set about right. However thier performance doesn't dominate any of the other 1944 monsters in the game, they are slightly better, which is why they're perked, but not good enough to survive the ensuing gangbang.
The prices are right, the gangbang tags make the planes NOT fun to fly, which ruins the entire point.
