GNUA13 is a mini paraglider "speedglider" with 25 cells
and 13 m2 of flat surface.
This prototype was built in May-June 2020 byThierry Bosq
in Hautes Alpes, France
It is the third prototype of this model, originally designed and built by Eric Fontaine (Tarnos,
and later by Oleg Egorov (Minsk,

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.
Builda paragliderat home is avery complicated task , and requiresmany
hours of work. Previous experience is required,andvery inventive.As alwaysremember 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
construction and test of experimental wings without certifying requires
deep knowledge of what is being made.
