de Havilland DH.65 Hound
|The modified DH.65A|
|First flight||17 November 1926|
|Primary user||Royal Air Force|
The Hound was designed as a two-seat general purpose biplane, a private venture to meet Air Ministry Specification 12/26. The prototype G-EBNJ first flew on 17 November 1926. It was of all-wooden construction, powered by a Napier Lion engine. In 1927, the nose and rudder were modified, it was fitted with a geared engine and received the modified designation DH.65A. It was delivered to the Royal Air Force in January 1928 receiving serial number J9127 for evaluation. While it showed superior performance to the other competitors for the specification, it was rejected because of its wooden construction and the order was placed with the Hawker Hart.
A project to further develop the Hound as a four-seat passenger transport under the designation DH.74 was left unrealised.
The design being otherwise unsuccessful, the second aircraft G-EBNK was not completed.
