Why in the world would the U.S. copy the FW-190? Lets be realistic here, the 190 was not spectacular in any category. It was even prone to high speed stalls. The only thing the Fw-190 and the F8F share in common is a large engine mated to a light airframe. I'm sure there is tons of evidence and data to show that the F8F was built from combat experience in the Pacific. In fact, I am going to dig some up. There is not more than a shred of evidence to prove the F8F was directly descendant from the FW-190.
Data, research, and evidence- what seperates the men from the liars.
