The hog can turn with anything at higher speeds. It also has one rather fun trick, the landing gear can be deployed up to about 400mph, acting as a speed brake. The corsair tends to retain E pretty well, but if you drop your gear, and slam the rudder to one side, you can slow down unbelievably fast. Conversly, if you're on an f4u's six, and you see the gear go down, you better be slowing down fast.
The f4u-1 is faster than the C or D(which i believe in AH have roughly identical performance) The D climbs better though. The f4u-1 seems somewhat more stable at low speeds, although the D seems to be able to turn just a little bit tighter. F4U-1 is an excellent perk-getting plane.
