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 stabilizer, 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. Plans are available through Dyke Aircraft.
