Vernon Oldershaw’s motorglider features a retractable power plant that can be used for takeoff and climb to soaring altitude. A 31-hp Yamaha snowmobile two stroke flat-twin engine drives a wooden pusher propeller and feeds from a N-gallon fuel supply. The shoulder-type wings are built with a spruce spar, plywood ribs, and plywood skin; the wing does feature ailerons and airbrakes. The fuselage is all-wood except for fiberglass skin from the nose back to the wing.
