F4UDOA,
I mean that speeds and climb rates of the F4U-1 and P-51B in that MSWFDATA.PDF gives us quite different picture than conclusions in mentioned comparison.
Anyway, if the Navy wanted to compare the future F4U-4 and the P-51, then it's probably correct. But if they wanted to compare the standard 1944 F4U-1 and the P-51B, then conclusions are quite strange.
