in Tour 27 I decided to give the F4U-1 a serious go and flew it almost exclusively, I don't spend an inordinate amount of time online but my K/D in that plane that tour wasnt bad (84/19) not quite as good as lazs but respectable none the less.
All I can do is reiterate what these gentleman have already said, there is no magic formula, there is'nt one move that will give you an advantage over any plane. For me the key is E and knowing the capabilities of your plane and the nme's. It takes time and practice to know what to do and when against what plane. Ofcourse there are the obvious: don't try to turnfight the spits, n1ks & zekes. don't try to climb with the 109's. Stay above the scissoring 190's. Lastly, GET ALTITUDE, a low/slow F4U is a challenge to keep alive in a fight, a notch of flaps help in the stalling turns if it gets that bad but try to avoid that situation.
One tip I can give is burn the Left Wing fuel tank first, this will lessen the effects if you stall the aircraft and make it more manageable.
