Design and development

de Pischoff had previously experimented with a biplane glider derived from Ferdinand Ferber's Type VI of 1904, and some elements of the earlier machine may have been used for the 1907 machine. This was an unequal-span, single bay biplane powered by a 25 hp (18 kW) Anzani engine mounted in the middle of the gap between the wings. Booms carried the aft-mounted elongated triangular fin and horizontal stabiliser, with rectangular rudder and elevator. It was mounted on a tricycle undercarriage with two front wheels below the wings' leading edge and a third aft of the trailing edge. Flight trials at Issy-les-Moulineaux in November 1907 were largely unsuccessful, although a flight of 500 metres was made on 17 December Progress of Mechanical Flight
