Silvercraft and SIAI Marchetti were aiming to produce a highly economical aircraft. The SH-4 had some original features such as the semirigid rotor and simplified mechanics, with parts which could easily be inspected from the outside and were quick to replace. The prototype flew in March 1965 with a six-cylinder Franklin engine. A pre-production model was displayed at the 1967 Paris Air Show, and a year later the SH-4 was certified by the American FAA and the Italian Aeronautical Register.

Production of a batch of about 50 SH-4s was started at the Sesto Calende works with the aid of Fiat Aviazione (Motori), who manufactured mechanical parts for the rotor transmission, but the firm ran into difficulties over the Franklin engine, which had gone out of production. An agricultural version of the SH-4 was developed, designated SH-4A. The company ceased operations in the late 1970s.
