Sud-Est S.E.3101

04/30/2009. Remarks by Ray Watkins: "Designed by Professor H. Focke and M. Renoux, the single-seat S.E.3101 helicopter was powered by a 99 hp Mathis G 4R four-cylinder engine. It was built to explore the use of the two canted tail rotors (to provide torque counteraction and yaw control by differential variation in pitch), each mounted at 45 degrees to the vertical at the end of small vane surfaces at the rear of the lattice frame work.

The first flight took place on June 15, 1948, with Jean Boulet at the controls. The sole S.E.3101 is preserved (site files) at the Musée de l'Air et de l'Espace, Le Bourget, Paris, France."
