Design and development

edit

A prototype was constructed in 1930–31 and made its maiden flight on 20 March 1931. The aircraft was, however, under-powered, and the flight characteristics were poor. Suggestions for improvements were made and the engine was replaced by a higher-powered one. The aircraft was damaged in 1933, but was never repaired.[1]
