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.
The American Will Schuemann pioneered several performance-enhancing modifications to the type, including a re-profiled wing, converting the airfoil to a Wortmann section, various fairings, a new canopy and a reshaped fuselage nose. Aircraft incorporating these changes are informally known as 'Schümanised' Libelles.[1]
The H-201 Standard Libelle was developed in 1967 as a Standard Class variant.
The Libelle was a popular and influential design. Its light wings and easy rigging set a new benchmark. Handling is generally easy except that it is sensitive to sideslipping and has relatively ineffective airbrakes that make short landings tricky for inexperienced pilots.
The H-201 Libelle (standard class) was superseded by the Hornet.
The H-301 Libelle (open class) was superseded by the Mosquito.
