There is a bias in AH community that the F4U was not a really good plane, but only kicked butt because it was flying against slow Zekes and other TnB type Japanese planes. Read above posts for details.
I would like to point out that the F4U is the only model in AH that has 50% of it's models perked. The unperked modles are an early and a mid war ride.
The Corsair above 400 mph still handles like a dream. I remember reading about some F4Us in Korea that went 2 on 2 with some Yaks, I think the model was later than the Yak 9, something like 10 or 11. The Yaks ate dirt.
In the MA the F4U early and mid war are expected to compete with the late war 190D9, Pony D, and LA7. And in the earlier versions of AH the F4U was quite competative (pre-perk, pre modified FM). And it while still is a competative bird I stick to the better non-perked aircraft in the game. That is the LA7, 190D9,
Pony D.
Why fly a mid war ride when you can have a monster?

Maybe if the C hog was cheaper, the perk icon was removed from the F4U-4 (and the cost lowered condsiderably), we would see a lot more Hogs and there would be fewer LA7s.
