Thanks for all those valuable information.

So basically what you are saying is as long as I flight USN fighters, I can forget about dog fight.
Also, about the choice between F4U and F6F, which do you thinks it's better?
By the way, is that true?? That F4F had a kill-to-loss ratio of 5.9:1 in 1942 and 6.9:1 for the entire war???
