Origin and Founding

In 1928, Star Aircraft, a division of Phillips Petroleum Co., was established in Bartlesville, Oklahoma. That same year, engineers E.A. Riggs and William Parker unveiled their design for the Star Cavalier A, a light multi-purpose aircraft.

This two-seat strut-braced high-wing monoplane was powered by a 90 hp (67 kW) Lambert R-266 five-cylinder radial engine. Three prototypes of this model were initially built, followed by three dozen more similar aircraft between 1929 and 1930.

Variants and Production

The most mass-produced variant was the Cavalier B, fitted with a 55 hp Velie M-5 engine. Several of the 15 machines built received Lambert R-266 engines, and others were fitted with the 80 hp British Armstrong Siddeley Genet.

One aircraft, designated Cavalier C, was equipped with a 60 hp LeBlond 5D five-cylinder radial engine. Additionally, two more machines, marked Cavalier D, were built with Genet engines.

Final Evolution

In 1930, 13 units of the Cavalier E, featuring the Lambert R-266 engine, were sold. The last variant in the family was also named Cavalier E, equipped with a Warner Junior engine, marking the end of the series.
