Vought-Sikorsky VS-300 cargo. The VS-300 was modified over a two-year period, including removal of the two vertical tail rotors, until 1941, when a new cyclic control system gave it much improved flight behavior. In 1943, the VS-300 was retired to the Henry Ford Museum in Dearborn, Michigan. It has been on display there ever since, except for a trip back to the Sikorsky Aircraft plant for restoration in 1985. Vought-Sikorsky VS-300 The Vought-Sikorsky VS-300 (or S-46) is a single-engine helicopter designed by Igor Sikorsky.

Sikorsky S-6 Sikorsky S-6 The Sikorsky S-6 was a Russian single engine experimental aircraft similar to the S-5, built in 1911 by Igor Sikorsky. Construction of the first S-6 was started in August 1911. The three bay biplane was powered by an Argus 4-cylinder water-cooled engine producing . Initial flight tests in late November were disappointing, revealing a long take-off run and poor climb performance. Sikorsky disassembled the aircraft and took it home where substantial modifications were undertaken, including lengthening the wingspan and reducing aerodynamic drag by enclosing the fuselage with wood veneer. Ailerons on the lower wing were removed and strut
