Igor
Sikorsky's quest for a practical helicopter began in 1938, when as the Engineering Manager of the Vought-Sikorsky Division of United Aircraft Corporation, he was able to convince the directors of United Aircraft that his years of study and research into rotary-wing flight problems would lead to
201:
The cyclic control was found to be difficult to perfect, and led to
Sikorsky locking the cyclic and adding two smaller vertical-axis lifting rotors to either side aft of the tailboom. By varying pitch of these rotors simultaneously, fore and aft control was provided. Roll control was provided by

engine. The VS-300 was one of the first helicopters capable of carrying cargo. The VS-300 was modified over a two-year period, including the removal of the two vertical tail rotors, in 1941, when a new cyclic control system gave it much-improved flight behavior.

by cables. In developing the concept of rotary-wing flight, Sikorsky was the first to introduce a single engine to power both the main and tail rotor systems. The only previous successful attempt at a single-lift rotor helicopter, the Yuriev-Cheremukhin

differential pitching of the blades. In this configuration, it was found that the VS-300 could not fly forward easily and
Sikorsky joked about turning the pilot's seat around.
