Design and development

The first example was built in Lille, France using a 1930 Clerget engine, but was abandoned due to replacement engine availability after the first 23 hours of flight.[2] In 1955 an enlarged version was designed by Gorges Jacquemin, increasing the wing area from 70 to 90 sq ft (6.5 to 8.4 m2). Power was from a Poinsard engine. It was marketed as a plans-built homebuilt aircraft by Falconar Avia.[3]

The aircraft is a single place, strut-braced parasol winged design, with conventional landing gear. The all-wood fuselage with plywood covering has a diamond shaped cross-section. The dual wooden spar wings have aircraft fabric covering. A fuel tank is mounted in each wing root. The design can accommodate engines with as low an output as 16 hp (12 kW).
