The Miller WM-2 was a single-seat sport aircraft designed in the United States in the early 1970s and marketed for home building. Although primarily a powered aircraft, the WM-2's high aspect-ratio wings enabled the pilot to stop the engine and soar on thermals as with a sailplane (designer W. Terry Miller's previous projects had been sailplanes).
It was a generally conventional, low-wing cantilever monoplane with a cockpit enclosed by a bubble canopy. The undercarriage, however, was a manually retractable monowheel with a tailskid behind it. The fuselage was of wooden construction, covered in plywood and fibreglass, while the wings and tail were built of wood and covered in fabric.
