Guyot et Verdier

   Guyot and Verdier were manufacturers at la Souterraine, in midwestern France, and built at least 2 biplanes, the first finished by the end of 1908. It was a tractor with front elevator and a tailplane at the far rear, with a large rectangular fin and rudder set immediately aft of the wings between the outriggers. The center-section of the top wing was bent slightly upward above the 40 hp flat twin engine on the lower wing, which drove an Antoinette-style propeller. 2 ailerons were hinged between the 2 outer struts at the leading edges of the wings.
   The second machine was finished in February 1910, and was taken to the hippodrome la Gueridiere at Dorat, near Clermont-Ferrand in mid-France. A large pusher biplane probably developed from the first and unsuccessful design, No 2 had a 60 hp ENV V8, and ailerons set into the upper wing trailing edges. The tailplane and inset elevator were fixed aft of a very large rudder. During the trials the engine was moved forward, and the metal propeller changed for a wooden one designed by Guyot, which broke soon after. The aeroplane had a wing area of 40 sqm - some said 50 - and was flying "fairly well" over Juvisy by June 1911. It was entered in the Concours Militaire of 1911.
