The Stolp-Adams SA-100 Starduster is an American single-seat sport biplane designed to be built from plans supplied by Aircraft Spruce & Specialty Co.

[1] The SA-100 Starduster was designed by Louis A. Stolp and George M. Adams as a light sports aircraft for homebuilding from plans.

[2] The fuselage and tail unit have a fabric covered steel tube structure, with the open cockpit positioned just behind the swept upper wing trailing edge which has a rounded cut-out for upward visibility.

There is a long and prominent faired headrest behind the cockpit, on top of the curved upper fuselage surface.

The Starduster has a conventional tail unit, with a wire braced tailplane and straight tapered, round topped fin and rudder, the latter extending to the keel between split elevators.
