gnuA1 sizes 20, 23, 27 m2
1. DESCRIPTION

gnuA1, or gnu "A", is the Laboratori begginer paraglider.  First released in 2015 and updated in 2021. As its name suggests, the desired level of difficulty will be "A" or "A-".

27 cells
4.3 moderate aspect ratio
20 m2 / 23 m3 / 27 m2 surface
20% thicker profile "gnuA" based on gnuLAB3 airfoil
very stable...

This glider is the one that I would fly at this time...!

As always, the plans are delivered free ("of freedom") to be studied and copied for any purpose, to make a prototype, or even serial units. You may copy the design, improve it (or not), change the colors and/or the name, suited to your tastes. It's easy to make a paraglider gnuA? No. Perhaps easier than others, but to build a glider like gnuA, it is necessary to be a paraglider specialist, and a real artist.

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.
