history

The H-301 was produced from 1964 to 1969 and was the first plastic airplane to be built in large numbers (more than 100 for the first time). It was many years ahead of the racing class created in 1975 . The H-301 served as a template for the H-20X Libelle series .

construction

The H-301 is a flap glider with a wingspan of 15 meters. Like the Janus, it is equipped with a braking parachute located in the lower part of the rudder. This allows the pilot to land a shorter time, which is beneficial for outlandings as it limits damage to the airframe (with most outlandings being damage free).
