The Caudron C.180 was a high-wing cantilever monoplane with metal structure and duraluminium covering.

The single spar wing was in three sections; the inner part carried the outer pair of 224 kW (300 hp) Lorraine 9N Algol 9-cylinder, air-cooled engines well ahead of the leading edge, cylinders exposed, on faired mountings which merged into the wing.

The flat-sided fuselage consisted of two parts, bolted together, and contained a cabin for ten passengers with a lavatory and luggage compartment.

Each main wheel was mounted on a half-axle hinged from the lower fuselage and located by a hinged trailing strut, with a vertical, shock absorbing leg to the outer wing centre section below the engine, providing a wide track.

[1][2] The exact date of the first flight is not known, but one source suggests 1930;[3] certainly the aircraft appeared, flown or unflown, at the December 1930 Paris Salon.
