Glider Reg. Number: N260E
1966
Design & Development
The Glasflugel H-301 Libelle is an early composite single-seat sailplane produced by Glasflugel 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.
In 1964 the H-301 Libelle ("Dragonfly") received the first German and first U.S. Type Certificate issued to an all-fiberglass aircraft. It had flaps, water ballast and retractable landing gear.
There are two canopy variants: the normal canopy and a sleeker, lower-profiled 'racing' canopy with no side vent. The canopy is unique in that it has a catch that enables the front to be raised by 25 mm (1 in) in flight to provide a flow of ventilating air instead of the more conventional small sliding panel used for this purpose.
