In 1911, MM. Voisin Freres experimented with a biplane characterized by the absence of a tail and the grouping of the elevation and direction rudders at the front, carried by a long central fuselage. This fuselage was attached at the rear to the main biplane cell. But airplane design moved quite the other way, as designers found that a tail unit including both elevator and rudder was the best concept.
The motor was a 50 horse-power Rossel-Peugeot, and droveÂ direct a two-bladed metal Voisin propeller, at the rear of the supporting planes. Its lateral stability was maintained by means of ailerons operated exactly as on the Voisin (Type Bordeaux). The main planes had a span of 39 feet, a chord of 7 feet, and an area of 380 square feet. The landing gear was on four wheels, two at the front and two at the rear, fitted with springs. The aviator sat in front of the main planes in the fuselage. and commanded a clear view of the rudders and of his surroundings. This type was experimental, but it displayed good stability and speed, and rose off the ground very quickly.
