Charles de Piquerez was an explorer who asked de Pischoff and Koechlin in December 1908 to build him a large biplane. The design had an engine in the middle of the fuselage, driving two pusher propellers via chains. Elevator(s) were mounted in the front and the end of the fuselage. Crew one pilot and a passenger. The biplane flew in at Issy-les-Moulineaux, France, in April and May 1909 but not very successfully, so it was radically redesigned as a monoplane (also with two pusher propellers), but alas this was not a great success too.
Powerplant: 1 x 40 hp 4-cylinder Dutheil and Chalmers engine.
