As first flown at Issy-les-Moulineaux by Maurice Colliex, the aircraft had an uncovered fuselage of wire-braced wood construction with the Rossel-Peugeot rotary engine at the rear and the front-mounted control surfaces consisting of an all-moving elevator divided into two halves, one either side of the fuselage, a rectangular balanced rudder mounted above the elevator, and a pair of short-span fixed horizontal surfaces with a high angle of attack mounted behind and below the elevators. Voisin's characteristic side-curtains were fitted to the outermost pair of interplane struts and roll control was achieved using trailing-edge ailerons on both upper and lower wings.
