K 8 / K 8 B / K 8 C

The K 8 was the first sailplane from Poppenhausen that did not get a name assigned to it. While In hindsight it looks somewhat obvious, in 1957 it was a risky business to bring an intermediate sailplane to the market to ease the transition from a two-seat trainer to high performance single-seat sailplanes.

Also worth noting is Karl Striedieck’s world record with his K 8 B.  On 3 March 1968 he made an out and return flight from his home airport Eagle Field, Pennsylvania, USA, over a distance of 767 km at an average speed of 71 km/hr.
