The aerotechnik WGM - 21 Helicopter
Article: http://gyrowiki.com/GyroWiki/aerotechnik%20WGM-21.aspx  "The aerotechnik WGM 21, a full-flight helicopter designed to use the BMW 54 hp motorcycle engine, appears to be one of the most sophisticated approaches to a small helicopter that we have seen in some time. The machine is designed around several patents by Mr. Muller, which are claimed to revolutionize the control systems of helicopters." .
