[1] During July 1929, the sole prototype, which was powered by a 400 hp (298 kW) Hispano-Suiza 12Jb inline piston engine, performed its maiden flight from Orly.

All four sections were assembled using quickly detachable joints, facilitating their easy dismantling for repair, replacement, or ground transport.

The engine bay was covered by a duralumin shell that formed the nose of the aircraft; it was attached via four bolts to tubes that traversed the central portion of the wing.

[4] The primary members of the landing gear were a pair of laminated wooden panels, one of which was directly attached to either side of the enlarged central section of the wing.

[6] Protection against capsizing was achieved via a relatively high windshield comprising steel tubes that were capable of withstanding stresses of up to 5000 kg (11000 lb.

The assembly of the engine block, fuselage, tail surfaces and landing gear could be taken along the road on its own wheels while the wing would have to be separately transported on a trailer.
