The wide success of the De Havilland Gipsy Moth led to the development of a faster aircraft with a welded tube fuselage featuring an enclosed cabin for more speed and comfort. The result was a high-wing monoplane known as the Puss Moth, which was essentially a two seat aircraft although three could be carried. The RCAF acquired the Puss Moth for instrument training and as a general communication high speed touring aircraft. An unusual feature of the aircraft was an air brake provided by turning the undercarriage strut through 90 degrees.
