Pilot Report - The Acrostar
by Dr. Urs Meyer, Sport Aerobatics, September 1981
Nine Acrostars have been built during the years 1969 to 1973 - mine carries Nr. 4009 and is the last ever produced. the Company Wolf Hirth Gmbh, Nabern/Teck, Germany, still has all tools and complete set of materials for at least one more airplane, but there is not chance that it will ever be completed due to the high price this latecomer would cost, probably about $90,000.

Prototype of the Acrostar in Museum
The Prototype Hirth Hi-27 Acrostar is current in the Deutsches Museum, Flugwerft Schleissheim, Germany. It was designed at the end of the 1960s by the aerobatic pilots Horst Gehm, Josef Hößl, Arnold Wagner and Walter Wolfrum in response to the demand for more powerful competition aircraft. The Wolf Hirth Company produced a total number of nine examples. First flight of the prototype was in 1970.
Thank you to Björn Kürten's email guess from the April issue of In the Loop. Björn Kürten knew the owner of the prototype. "He [the pilot] used to perform very nice classic aerobatics. It was a joy to watch him as the Acrostar was relatively slow (very think airfoyle) flying tight radii (marco-flap-system).
