The PDQ Aircraft Products PDQ-2 is a very basic light aircraft originally built in 1973 in the United States, and marketed as plans for a homebuilt aircraft.[1] It was a minimalist design, consisting of aluminum alloy tubes carrying the pilot's seat, a set of monoplane wings and a T-tail.[2][3] The pilot's position was fully exposed at the front of the aircraft.[2] Power is provided by a single engine mounted pusher-fashion on a pylon above the wings.[2][3] Originally, this was a Rockwell JLO snowmobile engine, but Ison revised the design to use a converted Volkswagen engine,[2] due to a lack of availability of the first choice of engine.[4] The heavier Volkswagen engine required an increase in structural strength, and the design was revised accordingly.[2][4] The wings have wooden spars with ribs, and skin of polyurethane foam, all coated in epoxy resin.[2][3] Fixed, tricycle undercarriage was fitted.[2]
