The F.380 was a low-wing monoplane that first flew in 1933. It was similar but smaller than the contemporary F.370 and was powered by a 155 hp (116 kW) Renault Bengali inverted inline piston engine. Like the F.370 it had streamlined features, including a shallow fin faired into the open cockpit headrest and fixed main monowheel landing gear faired into the engine and oil radiators of the engine. It was entered into the 1933 Coupe Deutsch de la Meurthe air race were the landing gear collapsed at the start of the race. Despite this setback, before the race it had broken the class world speed record at 303.387 km/h over a 200 km course.
