Design and development
The Martin-Handasyde No.3 bore a strong resemblance to the Antoinette monoplanes, with a slender wood-covered triangular section fuselage, and tapered wings which were braced by mid-span kingposts. Lateral control was by wing-warping and the angle of incidence of the wings varied from 5° at the wing root to zero at the tip. The undercarriage consisted of a pair of wheels on a cross-axle supplemented by a forward-projecting curved skid. It was initially powered by a 60 hp (45 kW) Antoinette V-8 engine. This was later changed for a 40 hp (30 kW) J.A.P..
It was first flown at Brooklands by H.P. Martin during November 1910, and was flown throughout 1912 by Graham Gilmour, who was eventually killed in the aircraft when it suffered a mid-air structural failure over Richmond Park on 17 February 1912.
A two-seater version of the aircraft, the Martin Handasyde 4B, also called the Dragonfly, with a wingspan of 37 ft (11 m) was built for Thomas Sopwith and was displayed at the 1911 Aero Show at Olympia.
