09/30/2015. Remarks by Walter van Tilborg: "The Mü-30 Schlacro two-seater was an original design of the Flugtechnische Forschungsgruppe and Akademische Fliegergruppe (Akaflieg) of the Technical University of München and was developed at the initiative of by Helmut Fendt, test pilot of the Akaflieg.
Work on the project started in 1985 and initial plans called for the installation of a 212 hp Porsche PFM3200 engine donated by the engine manufacturer. However, production of this engine was halted and from 1992 the Mu-30 was redesigned to adopt a 300 hp Lycoming AEIO-540-L1B5D engine. The prototype Mu-30 was nearing completion in 1999 and the aircraft made the first flight on June 16, 2000. The Mu-30 was suitable for use as specialized glider tug and as two-seat aerobatic trainer or sport aircraft hence the name (in German) Schlacro for Schlepp-Acrobatic (tug-aerobatic) and it was stressed to +/-10G. The aircraft was temporarily grounded in 2003 to undergo modifications connected with engine cooling and it was reflown on February 16, 2007."
