(in fact the two-seat Sage was smaller than many single-seaters of the time), with single-bay wings. The pilot and gunner sat in an enclosed, glazed cabin that filled the gap between the fuselage and upper wing. Because of the lack of effective gun synchronising gear to allow a fixed gun to fire through the propeller disc, a hole was cut in the upper wing above the gunners seat, so the gunner could stand with head and shoulders above the wing, giving him a good all-round field of fire for his Lewis gun, including forward over the propeller. The aircraft was powered by a
