Design and development
The engine was a simplified and smaller version of the earlier de Havilland Gipsy. It featured only one magneto where dual ignition was normal for the Gipsy series of engines. A total of 171 engines were produced, including 100 built in Australia, production moving to that country due to the start of the Second World War.[1]
