F4U > all
I went to Oshkosh last summer and was amazed to watch the climb rate of the F4U vs. the P-51. The P-51 climbed out at a reasonably impressive rate, then the F-4U took off after it and caught up to it while climbing three times as fast.
The P-51 is a nice airplane with a nice engine on the front. The F4U is a big ass engine with a plane stuck to the back of it.![]()

Know why the F4U has that kink in the wing?
The engine is huge, so it needs a huge prop.
Huge prop means tha nose has to be very high for it to clear the deck.
High nose means long landing gear.
Long landing gear is a bad idea on a carrier based aircraft.
So they put that kink in the wing to get the attachment point of the gear lower, so they could have shorter (stronger) gear, but still have the prop clearance.
Don't know if it's true, but that's the story I've heard.
And those old radial engines are amazing!
That was a big debate back then ... radial vs. linear engines. The problem with radial engines is the big draggy frontal area, but they scale better (just add another bank!). Linear engines like the Allison (or Merlin) V12 in the Mustangs and Spitfires are nice & slim, but in addition to the scaling problem, they have some serious cooling issues.
