FAG Chemnitz C 11

from Wikipedia, the free encyclopedia

The C 11 glider was developed and built at the end of the 1930s and the beginning of the 1940s at the aeronautical working group of the State Academy for Technology in Chemnitz (today Chemnitz University of Technology ). The fuselage consisted of a fabric-covered tubular steel frame. The supporting structure and tail unit consisted of a wooden frame that was also covered with fabric.
