HF II (Farman): In 1909 at Chalons, Farman built his second design: the II was a single-bay Gnome-powered tractor biplane with heavy vertical struts through both leading edges down to the front of the double skid arrangement. The rear ends of the skids were attached to the lower outriggers with big flexible hoops, with a small pair of wheels behind them to keep the ends of the skids from digging in. A big biplane tail cell with huge rudders brought up the rear; there was no forward elevator. The completed aeroplane showed a simple triangular brace in place of the distinctive hoops. A handsome pair of photographs in La Revue del'Aviation captions it Le Jabiru de Farman. He built No II and No III at the same time.
