Jurca MJ-7 Baby Mustang



To facilitate homebuilding replicas of fighter planes, designer Marcel Jurca has created a scaled-down ver-sion of the P-51 Mustang, the Supermarine Spitfire and the Focke Wulf FW-190. The Mustang is available in 2/3 (MJ-7) or 3/4 scale (MJ-77). Only the relative size of a pilot’s head identifies the Baby P-51 from its bigger brother. The ship first flew with a 200-hp Ranger inline engine. Others that can be used include: any of the six-cylinder Rangers, the 125-hp Mènasco, the 130-hp Gipsy Major, the 125 to 160-hp Canadian Rambler, or the General Motors Buick F58. Materials used are wood and fabric.

The Mustang replica is of all-wood construction and uses many components from the aircraft industry. It has a retractable undercarriage and conventional flight control surfaces and flaps. The fuselage, wings and empennage are of sitka spruce framework with a plywood covering and an exterior finish of thin fiberglass. It is powered by a six-cylinder Lycoming aircraft engine.




Although capable of carrying two persons, with the second seat removed and an additional fuel tank installed, the design represents the earlier P-51B with the high rear fuselage, rather than the more common P-51D with a bubble canopy.
The two-thirds scale replica P-51B Mustang is the model MJ-7-G.

Boeve Fiberglass Components Inc offered full kits (1997) for US$35,000. Plans were selling for US$500.
