It was a sleek shoulder-wing braced monoplane powered by a supercharged 8 cylinder 224 kW (300 hp) Hispano-Suiza 8Fb engine.

[1][2] The name Sesquiplane was due to the additional aerofoil that was attached to the axle of the fixed conventional landing gear.

[1] Two Sesquiplans were built and both were entered into the Coupe Deutsch de la Meurthe speed event held at Etampes in October 1921.

The aircraft flown by Sadi-Lecointe crashed during the race but the other, piloted by Georges Kirsch, won at an average speed of 278.36 km/h (173 mph).

[8][9] The last racing Sesquiplan, the Nieuport-Delage NiD 42 S was a new design, fitted with a 12-cylinder 447 kW (600 hp) Hispano 12Hb engine.
