Boeing Kaydet Biplane History
The Boeing Kaydet is one of the
most recognisable biplanes of all time. Originally designed by
Lloyd Stearman of Stearman Aircraft as the Stearman Model 75, it was
a relatively sophisticated and expensive aircraft. When Boeing acquired Stearman Aircraft in 1934 making it a subsidiary of Boeing they
effectively gained the rights to the Stearman Model 75 trainer and
renamed the Boeing Kaydet.
The Boeing Stearman Kaydet aircraft was
first introduced as a
tandem biplane military trainer in 1934, it was widely used by the USAAF,
USN and the RCAF with a total of over 10,000 aircraft being produced.

engine model fitted.
