The Stits-Besler Executive is a three place homebuilt aircraft designed by Ray Stits, as the Stits SA-4A Executive.^[1]

Development

The project was initiated when William Besler of Besler Corp. contracted Ray Stits to design a three-place homebuilt aircraft with folding wings.^[2] Besler was an early aviation experimenter, who had mounted a steam engine of his own design on a Travel Air 2000 in 1933.

Design

The wings on the Executive fold aft and upward. Fuel tanks are embedded in the non-folding wing roots. The fuselage is welded steel tube with fabric covering. The ailerons are mounted in the center of the wing rather than the tips.

Operational history

The sole Executive, (registration no. N36K), has been used as a test bed for Besler-designed engines; a 150 hp (112 kW) steam engine and a two cycle, four cylinder Vee rated at 100 hp (75 kW).^[3]
