Stegahorse,
Are you making this stuff up or did you really read that somewhere?
The P-47 had a very average roll rate compared to most contemporary fighters with the N as a possible exception. However I have never seen roll data on the N.
As far as the F4U being a stall fighter it wasn't in comparison with Japanese A/C. But compared to American Fighters it turned very well, inside the P-47 with ease as well as the P-51. The F4U had a stall speed roughly 20MPH below the P-47.
BTW, I have the British AFDU report on the F4U and F6F. I don't remember reading anywhere about being out classed in Europe.
Have you ever read the reports testing the F4U-1 vrs the FW190A5 or P-51B?
Also your HP ratings are way off.
The F4U-1 used the PWR2800-8 or 8W with water injection.
That engine put out 2,000HP at sea level with no water and 2,150HP in the early -1A and 2250HP in later F4U-1A/1D.
The P-47 with no water also put out 2,000HP and anywhere from 2300HP to 2600HP in later than the D27 model.
Even with that a 14500LB P-47D30 with 2600HP still has poor power loading compared to the F4U-1D at 2250HP.
P-47D-30
14,500LBS/2600HP= 5.57
F4U-1D
12,175LBS/2250HP= 5.41
Wingloading for turning is even worse for the P-47
P-47
14500LBS/300SQFT=48.33
F4U-1D
12,175LBS/314SQFT= 38.77
Hence the very high stall of the P-47.
Take a look here.
