No 5: The last Stablavion, a 2-seat pusher monoplane with an 80 hp Gnome, resembled No 3 but with a quadrilateral 4-wheel undercarriage, the Bleriot double pylon, and high vertical fins at each wingtip. It was tested at Issy in June 1914.

   Observers as late as 1913 reported that Arnoux had succeeded only with his gliders. After the War he worked with Felix Madon, the WWI ace with 41 confirmed victories, to develop a series of tailless racing planes under the name Arnoux-Simplex.
