The aircraft featured a wire-braced and strut-braced low-wing, two seats in separate tandem open cockpits with windshields, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft fuselage was made from welded steel tubing, while the wings had wooden spars and ribs covered in doped aircraft fabric. Several prefabricated components were supplied as part of the kit, including the fuselage frame, landing gear, engine mount and tail assembly. The manufacturer rated the STA kit as suitable for beginners and estimated the construction time from the supplied kit as 1500 hours. The kit could be completed to represent an STA, a military PT-16 or a PT-20.
The aircraft's 261NaN1 span wing had an area of 112.6square feet. The cockpit width was 22inches and the standard engine used was the 1000NaN0 CAM 100 powerplant. It had a typical empty weight of 725lb and a gross weight of 1275lb, giving a useful load of 500lb. With full fuel of the payload for pilot, passenger and baggage was 362lb.
In January 2014 no examples remained registered in the United States with the Federal Aviation Administration. Although one aircraft had been registered in 1997, it was listed as destroyed and deregistered in 2002. It is likely that no examples exist today.[2]
