The Lumière-de Monge racer[Notes 1] was built specifically to compete in the 1921 Coupe Deutsch de la Meurthe and was flown at Etampes on 1 October 1921.

[2] The racer was powered by a 220 kW (300 hp), liquid cooled V-8 Hispano-Suiza 8Fb engine, closely cowled and with a cylindrical Lamblin radiator mounted axially above the upper wing.

Its fuel tank was in the fuselage, which was built in a novel way based on an internal tapered tube with clamping frames around it.

[2] The Monge had a conventional tail, with a generous tailplane low on the fuselage carrying notched elevators and with an overall roughly oval plan.

However, the fighter's parasol wing was a completely new design, all-metal, swept and with a higher aspect ratio.
