Key Takeaways:

The JM-2 is a Formula I racing airplane designed by J.W. Miller, notable for its unconventional configuration with both the 100-hp Continental engine and main wings positioned aft of the pilot's cockpit, driving a pusher propeller.
Its innovative design includes the spinner serving as the tailcone, sections of the vertical propeller shroud acting as the vertical stabilizer, and elevators placed in a T-tail fashion.
Constructed from four fiberglass panels for the fuselage and honeycomb material reinforced by fiberglass and resin for the wings, the aircraft achieves a top speed of 235 mph and a cruise speed of 190 mph.

Designed by J.W. Miller, the JM-2 took a different approach to Formula I airplane racing. Both the engine and main wings are set aft of the pilot’s enclosed cockpit. A Continental drove a pusher prop; the spinner took the place of the tailcone. Two sections of the vertical propeller shroud act as the vertical stabilizer, and the elevators are placed in T-tail fashion. The wings are covered with honeycomb material reinforced by fiberglass and resin. The fuselage is constructed from four fiberglass panels.
