gnuA3 25 m2

gnuA3 is one step more, in the search for the perfect low end "A" paraglider. Of course, is the successor of the gnuA1 and the gnuA2

A3
A3 planform. Low AR=4.30, 28 cells. V-ribs in center, H-straps in divergent lines. Simplified set of lines, two levels, tree risers.
20% gnu-A airfoil. Mini-ribs (not draw), and 3D LE.

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.


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.
