GRAHAME-WHITE monoplane Type IX
W. Rowland Ding was the designer of this small single-seater with monocoque fuselage, which flew straights at Hendon for the first time on 7 September 1912 in the hands of Marcel Desoutter. The machine was a conventional braced monoplane with warping wings and twin skid undercarriage; a silencer was fitted to the exhaust system. The aircraft was under powered, and the 35hp engine was reported replaced by a 50hp Gnome, but even this did not solve the problems of the Type IX, and there was no further news of this machine.
Power:
Type A 35hp Anzani three-cylinder Y type air-cooled radial with silencer driving a 7ft diameter propeller
Type B 50hp Gnome seven-cylinder air-cooled rotary driving a 7ft 10in propeller
