Nowadays, Sikorsky is one of the major helicopter producers in the world. The fuselage is rectangular with very long nose and boat-hull bottom. Several rectangular windows run along either side of the fuselage. High-set wings are rectangular with rounded tips and are set far above the fuselage. Much smaller bottom wings are also present, but they serve mostly as mounts for additional side floats.
Several braces connect rectangular tailplane to the wings and the fuselage.
Two fins extend both above and below the tailplane. Landing gear with tail wheel is not retractable. The aircraft soon went in production and proved fairly popular among some airlines. First flown in the early 1932, the aircraft featured fully-metallic fuselage and wings along with more powerful engines and greater payload capacity. 4755 kg Max.
