Its one piece, single spar wing was strongly straight tapered to elliptical tips and was plywood covered with an outer layer of fabric.

It had an air cooled 110 kW (150 hp) inverted four cylinder 6.3 L (380 cu in) inline Renault 4Pei Bengali engine in the nose, driving a two blade, two position variable pitch propeller.

The Rafale's two seats were in tandem, one over the wing and the other behind the trailing edge, under a long (about a third of the fuselage length), narrow multi-framed canopy with a blunt, vertical windscreen and sliding access.

Behind the canopy a long fairing continued its profile to the straight tapered, round tipped vertical tail, which included a balanced rudder that ended at the top of the fuselage.
