Breguet 905 Fauvette
A postwar French sailplane designs, the Breguet 905 Fauvette (or Warbler) is a Standard Class single-seater with a V-tail and made its first flight in 1958. Like the Type 900 and 901 it was designed by J. Cayla.
Construction makes extensive use of Klegecel, the expanded plastic giving a very strong and light structure which
was used before in the Type 901. The fuselage is built in three main parts, consisting of the nose section of moulded plastic foam including the pilot's seat and flying controls; the centre fuselage, which is a steel tube framework covered with a moulded polystyrene skin and carries the wing, the cockpit attachment points and the towing hook; and the rear fuselage, which is of plywood/foam sandwich construction.
This sandwich is composed of 6mm plywood and 8mm of Klegecel, and the same sandwich construction is also used for the fixed tail surfaces, which can be folded to the vertical position for loading on a trailer; the movable surfaces are fabric covered. The cantilever single-spar shoulder wing is of similar plywood and Klegecel construction and has an NACA 63-series laminar flow section; the single spar is of wood and the air brakes are made up of a metal and Klegecel sandwich.
It was made available to customers either complete from the factory or in kit form for homebuilt assembly, and altogether 50 Fauvettes were built by Breguet.



The Fauvette soon made its mark in contest flying, and among the records set up in it was the United Kingdom distance record broken by Rear Admiral H. C. N. Goodharton 12 June 1959 with a flight of 388 miles.
