Navy aircraft to feature landing gear that retracted into a fully enclosed wheel well. The Corsair's aerodynamics were an advance over those of contemporary naval fighters.

Offsetting these benefits, the bent wing was more difficult to construct and weighed more than a straight one. Their solution was an inverted gull wing, a similar layout to the one used by Germany's Junkers Ju 87 dive bomber, considerably shortening the length of the main gear legs. To accommodate a folding wing, the designers considered retracting the main landing gear rearward, but for the chord of wing selected, it was difficult to fit landing gear struts long enough to provide sufficient clearance for the large propeller. To extract as much power as possible, a relatively large, 13 feet 4 inches (4.06 m) Hamilton Standard Hydromatic three-blade propeller was used.

The F4U incorporated the largest engine available at the time, the 2000 hp (1500 kW) 18-cylinder Pratt & Whitney R-2800 Double Wasp radial. When the prototype was built it had the biggest and most powerful engine, largest propeller and probably the largest wing on any fighter in history. UPDATE: F4U Corsair 1200 mm Project is complete you can download the PDF file below This plane will be my 7th design and build RC plane.ġ8-cylinder radial engine, rated at 1805 hp (1346 kW) went ahead quickly. After mock-up inspection in February 1939, construction of the XF4U-1 powered by an XR-2800-4 prototype of the Pratt & Whitney Double Wasp twin-row. The Corsair was designed by Rex Beisel and the Vought design team. Navy signed a contract for a prototype, the XF4U-1, BuNo 1443.
