2. The second aeroplane designed by Obre was designated No 3, equally unsuccessful, also tested at Issy in the summer of 1909. It was similar to the Henry Farman III, with a biplane forward elevator and biplane tailplane with a single rudder between. Ailerons were set into all 4 wing panels; the airfoil section was a gentle reverse curve similar to that on the odd upper panel of his first machine. It stood on 2 wheels under the engine, and 2 tailwheels at the tips of the tailplane. The engine was a 4-cylinder inline water-cooled model, possibly a 40 hp Chenu.
