Glasflügel H-301

what is it?

The Glasflügel H-301 Libelle is an early composite single-seat sailplane produced by Glasflügel from 1964 to 1969. The H-301 had camber-changing wing flaps so was required to compete in the Open Class because the Standard Class excluded wing flaps. It was often known as the Open Class Libelle.
