Hmm they all pretty sexy but, I will have to go with the F4U series from the -1 all the way up to the -4. Every model gives it that extra sexy but mean S.O.B look not to mention sound of the engine. Not to mention was the First fighter platform to be able a 4,000 lbs bomb payload 2x1,000# and 4x500#.
From the -1's birdcage to the -4's 4 prop blades with a nice round bubble type canopy to accent it's lines.
