C
gnu-C o "C" is a 60 cell, 6.25 aspect ratio, high performance paraglider. Is expected to incorporate the latest technical advances (shark nose, 3Dshaping, , three rows of lines, reduced total length of lines. Designed using leparagliding 2.60.
Still in development (winter 2016-2017).

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.
