The Sikorsky S-3 was an early biplane design by Igor Sikorsky and was a larger improved version of the S-2. Started in July 1910 and Completed in late November, the machine was powered by a 40 hp (30 kW) Anzani three-cylinder, air-cooled engine. Refinements included larger ailerons, improved fabric wing covering and tighter control cables.[1]
