Henri Guyot and Louis Verdier undertake, still at La Souterraine, the construction of a third biplane, two-seater, at Chauvière, 80 horsepower engine and pusher propeller, unequal span wings.
The front cell and the rear fixed plane are joined by V-shaped ash spars and to reduce resistance in flight, the masts and metal parts are profiled. The span of the upper plane is 17.50 meters and the span of the lower plane 15 meters, bearing surfaces with beak entry into the air profiled to avoid resistance to the advancement of the aircraft, the engine mounted on a fuselage which is fixed on the lower plane of the aircraft which constitutes the cockpit. The cell is mounted on skid with 4 shock absorbers metal fixed on two wheels on each runner. The wheels are mounted on balloon tires with bead rims, brakes on wheels and brake stand on the ground.
The first official flight, piloted by Louis, took place on April 24, 1910 at Le Dorat on the flat racecourse. It was completely fenced which facilitated the control of entries because the event was paying. It’s a rectangle of 50 meters by 60 meters, the aircraft can take off in all directions.
Louis passed his A.C.F. (Aéro-Club de France) on July 1, 1911 on this Guyot-Verdier aircraft. His pilot’s license civil bears the n° 538. The license n°1 was obtained in 1909 by Louis Blériot.
