The Stingray was a mid-wing fully cantilevered light sporting aircraft with a pylon mounted pusher engine designed by Mr Raymond Tolhurst and built in some numbers at the Camden facility of Composite Engineering in the 1980s.

The Acro Sport was designed by the late Mr Paul Poberezny, President of the Experimental Aircraft Association of America, specifically for construction by persons with no experience in building aircraft.

In 1985 the Aircraft Spruce and Specialty Company sponsored the design and construction of a light aircraft, the goal being to develop a new homebuilt aircraft that could be easily constructed from plans and / or building instructions and using commonly available materials.
