25 cells 13 m2 speed glider
GNUA13 Hautes Alpes
GNUA13 design


GNUA13 is a mini paraglider "speedglider" with 25 cells and 13 m2 of flat surface.

This prototype was built in May-June 2020 by
Thierry Bosq in Hautes Alpes, France
It is the third prototype of this model,
originally designed and built by Eric Fontaine (Tarnos, France),
  and later by Oleg Egorov (Minsk, Belarus)

Note: This wing flies and lands at high speed. It is necessary to be careful and use the appropriate technique, especially at high altitude and with weak winds.

LAB NOTE: Build a paraglider at home is a very complicated task , and requires many hours of work. Previous experience is required, and very inventive. As always remember that: The free flight implies risks that can only be known and they can be controled with a suitable formation on the part of a recognized school. Not test wings without knowing their functioning. The construction and test of experimental wings without certifying requires deep knowledge of what is being made.
