4. CONSTRUCTION

In October 2026 we have al least one gnuA7 prototype in flight!
I would like to remind you that the plans are freely available to private builders and companies, with or without modifications, for personal or commercial use

5. KIT THREE RISERS AND 2-3-2 LINES (size 26 m2)

Optionally, and without modifying the wing structure and diagonals, it is possible to install a kit of three risers using a minimalist 2-3-2 line configuration.

Thanks to Nicolas Leduey for sharing his project.

LAB NOTE: Build a paraglider at home is a very complicated task (even simple skin), 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.
