F4u is very good at speed, remember the gear can be used as airbrake too if u need to make anyone overshoot.
When im flying f4u in MA, i spiral climb up to 7 - 10k depending on alt of fight, pick a target out. anticipate where he will be (so not to pull G's to waste E trying to hit target), dive on him, attack, pull vert until you feel comfortable, level off, (dont lose control, as u get used to plane you will be able to level off at slower and slower speeds) pick another target and attack again.
I try to keep flying as vertical as possible. Get right above target so he does not have any escape routes, whichever way he breaks its just a quick roll for the f4u to get shot off.
I also like doing a feint attack on a target who keeps breaking low or something. to do this i just start the attack, i pull up as soon as i see him starting the evasives, roll inverted and keep my eye on him, as he is coming out of the move - then i hit him. It is likely he would have lost sight of you, has low E or both.
