The "Kakadu" was the first high performance glider designed by the young Akaflieger. It was ready for the 1928
Rhön competition. It was descibed as the ancestor to the famous glider "Fafnir" and "Austria" . The "Kakadu" ,
named after its designer Dr. August Kupper, was with its wingdesign, high aspectratio a signal where to go with
future desines. Wingprofile Göttingen 652.  It was the best glider even into the thirties and was used for research in
the alps
In the opinion of most of the experts the Munich group's improved high-performance glider "Kakadu" was the most highly thought-of machine at the Rhön meeting 1929. The Munich team had only altered the ailerons as far as the wing was concerned ; on this occasion each wing-tip was joined to the aileron to form a balancing horn. The body on the other hand was completely rebuilt. The new body is longer and has a substantially smaller cross-section. In fact this cross-section turned out to be almost too small, so that the pilot's head came out into the open in front of the wing. During the Rhön 1929 contest, the machine was flown by Krebs of Munich, and this time it thoroughly came up to expectations Unfortunately the wing showed somewhat large distortion in normal flight, so that the machine was not flown during very gusty weather. An exact investigation of the weight of the wing has shown moreover that the specific wing weight is somewhat high at 6.9 kilograms per square metre (while the wing of the "Wien" weighed only 4.5 kg. per square metre).
