The
M.3 Falcon was a clean, single engined low-wing monoplane with trousered main undercarriage and fixed tail-wheel, designed in
1934. It was structurally similar to the earlier
Miles M.2F Hawk Major family, but had side-by-side seating for two behind the pilot in a glazed cockpit. It was powered by a
de Havilland Gipsy Major piston engine. The prototype,
G-ACTM, built by
Philips and Powis first flew at
Woodley Aerodrome on 12 October 1934. The first production aircraft (designated
M.3A Falcon Major) was flown in January 1935. It had a wider fuselage than the prototype to improve passenger comfort and revised glazing with a forward sloping windscreen. The M.3A was somewhat underpowered, so the (
M.3B Falcon Six) and later versions were fitted with a
de Havilland Gipsy Six engine. The
M.3C Falcon Six was a four seater with dual controls. The
M.3D was strengthened to allow an 11% increase in all up weight compared with the M.3B. The final versions were the
M.3E and
M.3F. An enlarged five-seat version was developed as the
M.4 Merlin. ==Operational history==
