F4U does one thing very well... E fight. It can dive very well, and it's pretty fast. It handles very well at high speed, and it rolls well. This means you need and E advantage to win a fight in a Hog, and you must use good E-fighting techniques. That doesn't mean you can't get tracking shots or that you have to BnZ, it just means that you use the vertical when you can, and you use things like yoyos and lag pursuit to use your higher energy state to get a kill. You also need to realize when you no longer have enough E advantage to win, and know how to escape at that point. (With a 0G dive toward home or fiendlies).
Energy fighting takes a great deal of skill and patience. E-fighting in a plane like the Hog can be very challenging, because there are many planes that are faster than you are, and many more that can out-turn you and out accellerate you. It's possibly the most difficult style of fighting, but it's (IMO) the most deadly and most rewarding. I love flying the Hog, it's my #2 after the Jug. It's a pure E fighter, it's tough, and it's got all the tools to get the job done. It's also frequently under-estimated by your opponent, wich is always a benefit!
