Design and development Edit
The project to produce a batch of Bücker Bü 131 Jungmann replicas was headed by B&F's Peter Funk. Production commenced in 2013 with an initial batch of ten aircraft. The aircraft were to be eligible for the Fédération Aéronautique Internationale microlight rules at a gross weight of 472.5 kg (1,042 lb) and experimental aircraft rules at a gross weight of 520 kg (1,146 lb).
The aircraft duplicates the original 1934 Bü 131's construction. Its 7.25 m (23.8 ft) span wing is supported by cabane struts and a single set of parallel interplane struts outboard on the wings, with wire bracing. The standard engine used is the 82 hp (61 kW) Walter Micron IIIC four-stroke, inverted four cylinder, air-cooled powerplant.
