Design and development
The Stingray features a strut-braced parasol wing, a single-seat enclosed cockpit under a bubble canopy, retractable conventional landing gear and a single engine in pusher configuration.
The aircraft is made from a combination of metal tubing, with its flying surfaces covered in Dacron sailcloth doped aircraft fabric and a reinforced fiberglass hull. Its {{convert|30.83|ft|m|1|abbr=on}} span wing has a wing area of {{convert|150.0|sqft|m2|abbr=on}} and is supported by a central pylon behind the cockpit, "V" struts and jury struts. The wing also mounts outrigger pontoons that provide stability on the water. The acceptable power range is {{convert|40|to|65|hp|kW|0|abbr=on}} and the standard engine used is the {{convert|40|hp|kW|0|abbr=on}} Rotax 447 twin cylinder, two stroke powerplant.
The Stingray has a typical empty weight of {{convert|475|lb|kg|abbr=on}} and a gross weight of {{convert|800|lb|kg|abbr=on}}, giving a useful load of {{convert|325|lb|kg|abbr=on}}. With full fuel of {{convert|6|u.s.gal}} the payload for the pilot and baggage is {{convert|289|lb|kg|abbr=on}}.
The standard day, sea level, no wind, take off on land with a {{convert|40|hp|kW|0|abbr=on}} engine is {{convert|190|ft|m|0|abbr=on}} and the landing roll is {{convert|220|ft|m|0|abbr=on}}.
The manufacturer estimates the construction time from the supplied kit as 350 hours.
