The Macfie Monoplane was a British shoulder wing tractor monoplane. The aircraft was powered by a 35 hp (26 kW) J.A.P. V8 engine fixed at the front of an open-frame 'fuselage' at the rear end of which a tailplane and vertical rudder were mounted. The Monoplane was designed built and flown by Robert Francis Macfie who later as a member of the 1915 British Landships Committee made a significant contribution to the development of the armoured landship or tank.
