The Miles M.7 Nighthawk was a 1930s British training and communications monoplane designed by Miles Aircraft Limited.
Design and development
[edit]The M.7 Nighthawk was developed from the Miles Falcon Six intended as a training and communications aircraft. The prototype, registered G-ADXA, was first flown in 1935, it was a low-wing monoplane powered by a 200 hp (149 kW) de Havilland Gipsy Six piston engine. The prototype crashed during spinning trials at Woodley Aerodrome in January 1937. Four production aircraft followed.[1]
The design was modified to meet an Air Ministry specification and produced as the M.16 Mentor.[2] In 1944 a Nighthawk fuselage was fitted with the wings from a Mohawk and fitted with a 205 hp (153 kW) de Havilland Gipsy Six Series II engine with a variable pitch airscrew. It was designated the M.7A Nighthawk.[1] The last Nighthawk to remain airworthy was G-AGWT in the early 1960s. This aircraft was raced in many postwar UK air competitions, but is no longer extant.
Operational history
[edit]Two aircraft were delivered to the Royal Romanian Air Force in 1936 and one was delivered to the Royal Air Force in May 1937 with serial number L6846.[1] It was used as a VIP transport by No. 24 Squadron RAF.[3]
