Design edit
Ray Stits designed 14 different homebuilt aircraft kits that were some of the first available to the general public built in quantity.[2] Stits is also known to the general public as the maker of the Stits Junior, Stits SA-2A Sky Baby,[3] and Stits Baby Bird, each of which was once the world's smallest aircraft.[4] Engineer Harold Dale assisted in the certification process after completing his Dale Weejet 800.[5]
The Skycoupe was provided as a kit with a pre-fabricated steel tube fuselage. The surfaces are fabric covered. The aircraft was designed to accommodate engines ranging from 60 to 90 hp (45 to 67 kW).
