I didn't know for instance that the gull wings were a compromise to keep the huge prop (necessary for its speed and acceleration) from hitting the ground without making the retractable wheels too high and unstable for carrier use. That however cost them fuel storage room in the wings, so the Corsair had an additional fuel tank in front of the cockpit, which in turn forced an elongated fuselage/long nose, making landing visibility for the pilot poor - not a great idea for a carrier-based plane (one reason why the US Navy preferred Hellcats on carriers while the Marine Corps Aviation pilots flew their Corsairs land-based)! And to boot, that front-of-cockpit tank often leaked in flight, obscuring the frontal view of the pilot with kerosene. Those tape markings some Corsairs had ahead of the cockpit windshield? A makeshift effort to keep the not properly sealed fuselage tank from leaking, no joke.
I understand that the Corsair was manufactured in a decentralized manner, lots of facilities/plants involved. That - together with being a rushed wartime design - might have been behind the teething problems it had. By the time of the Korean War, it was of course a vintage design with all flaws ironed out.
