drgondog,
I am only right on this matter.
A weight of 9,100 lbs is not the normal gross weight of the P-51B, that is 9,202 lbs (4,173 kg), and the normal gross weight of the P-51C is ~9,350 lbs (4,241 kg), 9,760 lbs (4,427 kg) for the P-51D and 9,530 lbs (4,322 kg) for the P-51H - which equals the wing loadings below:
P-51B = 192 kg/m^2
P-51C = 196 kg/m^2
P-51D = 204.4 kg/m^2
P-51H = 200 kg/m^2
The F4U-1 has a gross weight of 12,039 lbs (5,460 kg), and the F4U-4 a gross weight of 12,405 lbs (5,626 kg) - which equals the wing-loadings below:
F4U-1 = 187 kg/m^2
F4U-4 = 192.8 kg/m^2
Now on top of this advantage in wing-loading the F4U Corsair also has the advantage of the NACA 23000 type airfoil providing a higher CLmax and critical AoA, giving it an even better lift-loading. While the laminar type airfoil of the P-51 suffers from a low CLmax and critical AoA and is known for its early, sudden and violent departures in turns.
And here's first the facts and then the doc's to prove it:
Fact no.1: The FW-190 G-2 turns with the Mustang III.
Fact no.2: The F4U-1 is superior in every aspect of maneuverability compared to the P-51B.
From Birtish AFDU trials between FW-190 G-2 and Mustang Mk.III:
"Turning circle
42. Again there is not much to choose."
- And this is against a FW-190 G-2 running at lower power than usual.
From US Naval evaluations and comparison trials of F4U-1 and P-51B, Patuxant River, Maryland:
