Goodyear produced a number of Corsair models identical to the Vought models. But since it was easier to interrupt Goodyear production than Vought, some experimental models were also constructed. Most notably the F2G series which featured an entirely new engine; the Pratt-Whitney R-4360-4 "Wasp Major". The airframe received significant alterations in order to mount this engine. The Wasp Major could deliver 3,000 hp (2,238.8 kW) for take-off and 2,400 hp (1,791 kW) at 13,500 feet (4,114.8 m). Top speed was 431 at 16,400 ft (4,998.7 m). It was armed with four .50 cal. (12.7 mm) Browning machine guns with 300 rounds per gun, and could carry two 1,600 lb (725.8 kg) bombs on wing pylons. The F2G-1 was the land based version, while the F2G-2 was the carrier model. Although hundreds were on order by August 1945, only 5 examples of each were built due to cancellations at the end of hostilities. All ten of these were sold as surplus, and a few could be found at various air races around the country after the war.
