John Dyke wanted a high-speed airplane with folding wings that would be compact enough to tow home for garage storage — thus the unique delta design. The basic fuselage skeleton, vertical stabalizer and wing spars are of welded steel tube. The wings have an all-metal frame and have been tried with either fiberglass or aluminum covering. Virtually the entire planform surface of the Delta provides lift at cruise speeds. A 180-hp Lycoming provides the power. First flew 1966
