The Republic RC-3 Seabee is an all-metal amphibious sports aircraft designed by Percival Spencer and manufactured by the Republic Aircraft Corporation. The RC-3 Seabee was designed by Percival Hopkins "Spence" Spencer. An aviation pioneer, he built his first hang glider in April 1911 at the age of 17 from plans he found in a Popular Mechanics magazine. On May 15, 1914, Spencer made his first powered flight in a Curtiss flying boat. In 1937, he joined Sikorsky engineer Vincent A. Larsen to design their first and only amphibious aircraft, the Spencer-Larsen SL-12C. Development of the plane progressed slowly and in September 1940 Spencer left the partnership to form his own company. His resulting design was the Spencer S-12 Air Car Amphibian. Construction of the S-12 began on March 1, 1941 and the small, two-seat S-12 prototype, registered NX29098, made its first flight on August 8, 1941. The S-12 was a fabric covered amphibian with a unique boxlike forward cabin; a high wing with a two-bladed propeller in pusher configuration; and a long, slender tail boom. In order to meet the anticipated postwar demand for civilian light aircraft, Republic endeavored to build the Seabee as inexpensively as possible, while still retaining reasonable performance and range. A lot of thought went into eliminating what were at the time termed as 'airplane frills,' resulting in a strong product built with as few parts as possible. For example, Seabees as built did not have ribs in the wings; instead, the heavy corrugated aluminum sheet which formed the skin provided the necessary stiffness. Republic was also willing to buy components in volume, which lowered costs further. On November 22, 1945, the prototype RC-3 (NX87451) came off the assembly line at Republic's factory in Farmingdale, New York and on December 1 made its first flight in Farmingdale with Spencer at the controls. On December 27, 1945, Republic Aviation purchased Aircooled Motors, manufacturers of the Franklin engine, to supply and build engines for the RC-3 Seabee. In March, 1946, the first production RC-3 Seabee was completed (NC87457, formerly NX87457, and on July 25, 1946 the first Seabee (NC87463, production #13) was delivered at the Republic factory to J.G. (Tex) Rankin of Rankin Aviation Industries of Tulare, California. For more information on the developmment, production and operational history of the Seabee, click here.
