is the latest update of the beginner paraglider from Laboratori
d'envol. As its name suggests, the desired level of difficulty will
be "A" or even "A-". The first design has been
completed on February 2015, using the program LEPARAGLIDING version
2.40. Later updates in June 2020 using LEPARAGLIDING 3.10 includes
mini-ribs, nylon rods, 3D-shaping, new lines, and new skin tension.
Main features: 27 cells, 4.3 moderate aspect ratio, 20% thicker profile
based on gnuLAB3 airfoil, large sizes, very stable... This
wing is completely defined in digital format, in a compressed folder,
which contains the subfolders “dxf”
(edited CAD files), “lep” (LEPARAGLIDING files), "pre1.5" (pre-processor files, “png” (png illustrative files).

Laxman Rawat special prototype (scaled to 15 m2) march 2021:
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.
