The gull wing also had some other unintended side effects. And, as a by product of the gull wing design, the wing also improved the aerodynamics of the intersection where the wing attaches to the fuselage, boosting the top speed of the aircraft. The wing design, also, produced a wicked stall characteristic in the early model (F4U-1). Just as stall speed was reached, the left wing tended to drop like a rock. It made the landing pattern dangerous for inexperienced pilots and made carrier landings almost impossible. That nasty stall characteristic is where it derived its nickname as the "ensign eliminator". This tendacy was fixed in the -1A model by adding a small spoiler to the leading edge of the starboard wing outside of the guns, which reduced the violence of accelerated jobs. The other problem with the F4U-1 was it's oleo landing gear. When the Corsair trapped, the stiff oleo landing gear would bottom out and the recoil would cause the U-Bird to bounce high into the air, which usually resulted in a wrecked airplane. This was fixed by altering the air/oil level in the oleo struts. This visibility problem was reduced by raising the seat eight inches. Most of the problems were worked out with simple solutions, and the corsair was given the go carquals again in 1944, where it past Bu Aero inspection.
The only full USN squadron to car qual the corsair before 1944 was VF-17 "The Jolly Rogers". They were scheduled to deploy on the USS Bunker Hill into the Pacific, but at the last minute they yanked from from the ship and put on shore assignment in the South Pacific were they became the highest scoring Corsair squadron in the war. Incidently they also operated off the Bunker Hill and the Saratoga for a few days during their deployment, again proving that the Corsair could be operated from a carrier deck.
The reason for their being pulled from the Bunker Hill was the logistics nightmare that supporting one F4U squadron in a deployed fleet full of F4Fs, so they were sent to the SoPac with the Marines, where there was logistics support.
If you want more info on the Corsair or VF-17, I suggest two books:
The Jolly Rogers, by John Blackburn ( the CO of VF-17)
Corsair, by Barrett Tillman
If you look in my profile that, me in the CAF's FG-1D based out of Dallas. It is truly a massive engine piston fighter! The the -1, -1A, -1C, -1D, and -2s do not have floors in them. Instead, their are two channels that the pilot puts his feet in with nothing but a cavern below. The cockpit is huge compared to that of a P-51, which I also had to chance sit in, I felt I had to put the thing on.
