Air Show - Part 5 - Tiger Moth

TIGER MOTH OVER DUNVILLE

In the 1920's, the de Havilland Aircraft Works developed a line of light aircraft, intended to be affordable and easy to fly for the average man. They were called Moths, in recognition of Geoffrey de Havilland's renown as a lepidopterist. The first model, introduced in 1925 became the D.H. 60 Cirrus Moth. It was a simple yet strong spruce and plywood box section design, powered by a four cylinder 60 horsepower engine.

    In 1927, a variant  was introduced with a new, improved inline inverted four cylinder engine. This  became the famous GYPSY MOTH. It proved powerful and reliable, and many light plane records were broken all over the world. Not only did it advance the cause of civil aviation, but it was seen to be an ideal training aircraft as well. The Royal Air Force had been using this type for elementary instruction  for several years when the Air Ministry issued specifications calling for an improved version. D.H. 60 fuselages were used, but the wing centre sections were moved forward while the outer sections were moved back. This distinctive swept wing configuration kept the centre of gravity constant with the changes that were necessary. Thus was born the D.H. 82 TIGER MOTH.
 For 15 years this became the foremost primary trainer throughout the commonwealth and elsewhere. It was the dominant type used in the British Commonwealth Air Training Plan and thousands of military pilots got their first taste of flight in this robust little machine.


Altogether, over 9000 of these aircraft were made, 1,784 D.H.82C's being built by De Havilland Canada under license. The Canadian models featured a tail wheel, a stronger undercarriage with wheels set farther forward and a sliding canopy for protection from the elements.
 After the war they were universally and inexpensively available for flying clubs and individuals. Numerous examples are still flying today and they will always be fondly remembered for providing flying in its purest form for so many.
