Design and development

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. The fan shroud structure provides a place to mount the rudders and the tailplane is mounted high in T-tail configuration as an extension of the shroud. There is a small canard surface mounted on the nose. [1] [2]

The aircraft is of mixed construction, with the fuselage made from four fiberglass panels and the 15.0 ft (4.6 m) span wing covered in fiberglass and resin-reinforced honeycomb material. As required by the Formula One rules, the engine used was a 100 hp (75 kW) Continental O-200B powerplant, the "B" being the pusher-configured version of the engine. [1]

The JM-2 has an empty weight of 630 lb (290 kg) and a gross weight of 1,100 lb (500 kg), giving a useful load of 470 lb (210 kg). With full fuel of 12 U.S. gallons (45 L; 10.0 imp gal) the payload is 398 lb (181 kg). [1]

The JM-2 was further developed into the one-of-a-kind racing aircraft, the Miller-Bohannon JM-2 Pushy Galore. [3]

Operational history

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. None of the aircraft remain registered. [4] [ as of? ]

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. [5] [6]
