This BHL-P model is 22.5 m2 in size, obtained from size 25 m2 using scale factor K=0.94812. This model uses the LEparagliding latest version (2.33), which fixes some minor bugs of previous versions. In addition, at the request of the builder, incorporates two new features:
1) Only two levels of lines (main and top), with the aim of reducing the number of individual lines
2) Horizontal line segments between vertices of divergent  triangles, to reduce the rotation angle of the triangles, and at the same time increase the global trasversal cohesion.
This glider is  intended for thermal flight in the Pampa plains, towed by van on the roadside tracks.

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.
