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. The Gadfly was a low-wing monoplane
with a fixed conventional landing gear and an open single seat
cockpit. The first aircraft, powered by an 35 hp (26 kW) ABC
Scorpion II engine, first flew at Brooklands in April 1929. It
was designated the Gadfly I and was registered G-AAEY. 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 the 16th of May 1929 piloted by G.L.P.
Henderson. The second aircraft was a Gadfly II G-AARJ which first
flew in August 1929 and was exported to Canada, where it was
damaged beyond repair at Kitchener, Ontario, on the 25th of August
1931. The final aircraft was Gadfly III G-AARK which was the
same as the Gadfly II but fitted with a 40 hp (30 kW) Salmson
A.D.9 radial engine. It was withdrawn from use in 1930. The first
aircraft G-AAEY was last based at Wolverhampton when it was scrapped
in June 1934. |
