I find the F5U infinitely more interesting, because it's something other than one or more aerodynamically useless tubes with wings sticking out of them. No, a mild bend to the F4U's main wings does not make it more interesting by any significant degree.
Blockland needs a flying, fighting pancake such as the F5U.
The F5U was designed to have either an equal or greater armament to the F4U, of either six .50 caliber machine guns or two .50 caliber machine guns and four 20mm autocannons. There was also a possibility for it to carry two 1,000-pound bombs.
In terms of design, the F5U had a stall speed as low as 20-30 miles per hour, up to a top speed capable of rivaling early fighter jets. These, combined with the ludicrously aerodynamically efficient design, made the F5U unbelievably maneuverable, and the exceptionally low stall speed combined with its carrier-based nature meant that the plane likely wouldn't even need to use a tailhook when landing on a ship!
In terms if structural integrity, they failed to be able to scrap the prototype via conventional methods, so they dropped a wrecking ball normally reserved for buildings onto it... only for it to bounce right off, so they had to carefully calculate exactly where to drop it before the plane finally broke apart so they could scrap it.
Stratofortress already made the P-51D (a plane which, according to wind tunnel tests and calculations of the latter, is not a fast, maneuverable, nor offensively powerful as the F5U) and Bf 109 something or other (I have not specifically compared these two yet, but I am absolutely certain that the same applies here), so I would rather not have yet another singe-prop-job-attached-to-a-tube-with-wings plane when we could have flying fighter plane pancakes instead!
