[1] Miller opted for an unorthodox configuration in developing a racing aircraft that would be as fast as possible on 100 hp (75 kW).
The JM-2 features a cantilever mid-wing, a single-seat enclosed open cockpit under a bubble canopy, tricycle landing gear with fixed main wheels and a retractable nose wheel, and a single engine in pusher configuration, mounted within a fan shroud, with the spinner acting as the aircraft's tailcone.
With full fuel of 12 U.S. gallons (45 L; 10.0 imp gal) the payload is 398 lb (181 kg).
[3] By October 2013, three examples had been registered in the United States with the Federal Aviation Administration including the sole Miller-Bohannon JM-2 Pushy Galore.
One of the two stock JM-2s built was destroyed while racing in the Reno Air Races at Reno, Nevada on 15 September 1989, when it flew through a dust devil and broke up in flight, killing the pilot.
