The Henderson-Glenny H.S.F.II Gadfly was a British single-seat low-wing monoplane designed by K.N. Pearson and built by Glenny and Henderson Limited at Byfleet, Surrey, England in 1929. [1]
The Gadfly was a low-wing monoplane with a fixed conventional landing gear and an open single seat cockpit. [1] The first aircraft, powered by a 35 hp (26 kW) ABC Scorpion II engine, first flew at Brooklands in April 1929. [1] It was designated the Gadfly I and was registered G-AAEY. [2] It was fitted with Pearson rotary ailerons and re-designated Gadfly II when it achieved a world altitude record of 3,021 m (9,911 ft) in the 200 kg class on 16 May 1929 piloted by G.L.P. Henderson. [1]
The second aircraft was a Gadfly II G-AARJ [3] which first flew in August 1929 and was exported to Canada, where it was damaged beyond repair at Kitchener, Ontario, on 25 August 1931. [1] The final aircraft was Gadfly III G-AARK [4] which was the same as the Gadfly II but fitted with a 40 hp (30 kW) Salmson A.D.9 radial engine. [1] It was withdrawn from use in 1930. [1] The first aircraft G-AAEY was last based at Wolverhampton when it was scrapped in June 1934. [1]
