Kent Misegades' KZ VIII

Posted by EAA 1114 Webmaster on September 21, 2011 at 9:30 AM

If I had a clone and a large walkout basement full of tools like Jack Phillips does, I would build a KZ VIII.  A design from the prolific Swedish engineer Bjoern Andreasson (Buecker Bestmann and Jungman, Cynet, MFI-09, SAAB Sonnett sports car, etc.), it is said that the KZ VIII inspired Walter Extra to stop building Pitts and develop his early monoplane aerobatic ships.  Its line are sensuous, and I like working with wood.   Niels Nielsen and I have seen two of only three KZ VIIIs in the world at the great Danmarks Flymuseum in Stauning, Denmark.  The picture here is of a recent creation, a blue KZ VIII built and flown by former Danish Air Force Draken/F-16 pilot Hardy Vad.  The white and red one is an original, with an inline engine.

Hi Kent,
yes,the KZ VIII is the forerunner of German aerobatic aircraft, the Hirth Hi 27 Acrostar. It was designed by a group of German aerobatic experts around Walter Wolfrum and the Swiss acro pilot Arnold Wagner. The Acrostar was an advanced design with an interesting system operating flaps and elevator as a function of the aircrafts attitude. Unfortunately the Acrostar suffered from its high price and even more from the Franklin engine which produced a lot of problems.

Walter Extra acro designs were inspired by Leo Loudenslagers Acrolaser.

Best Wishes
Thomas

The third KZVIII appears to be somewhere in the UK. It was registered temporarily in Germany and in Switzerland before going to the UK.

This third airplane was used by the German Aero Club around 1970. I have the German type data sheet. At this time, the German Aero Club also converted a Buecker Jungmeister with a Franklin engine, 220 HP. The final result was the Hirth HI 27 Acrostar, designed by Arnold Wagner, again with the Franklin 6C350A.

The Extra airplanes were designed much later. Their acenstry is the Laser. Different concept, built around the Lycoming AEIO540.


Hallo Herr Meyer, Gruetzi!

Niels Nielsen visited with Hardy Vad this past summer. They are putting all the KZ plans onto CDs and planning to sell these. Niels has talked with Hardy about scaling things up slightly for larger pilots. A very nice design for someone with skills, tools, and a LOT of extra time.

Kent, those are really nice looking airplanes.......


Indeed, especially the version with the inverted inline engine. They are 100% wood, and complicated to build. They remind me a bit of a Chipmunk. Niels Nielsen is considering building one, scaled up by 10% or so for a better fit.
