This BHL-2 "JPS" model is 23 m2 in size, obtained from BHL-2 "classic" version. The main differences are on the trailing edge, near the wing tips, finished with a crescent between ribs. Small nylon rods help maintain this shape in the trailing edge. This is to improve aesthetics, and perhaps the airflow in this area when the brake is applied. The ribs are not the classic sawtooth shape, are complete and without holes. This is an experiment proposed by the constructor to minimize wrinkles on the surface of the wing. The number of anchors per rib is 4 and 3, as in the classic model.

3. Construction

The first prototype has been built (Octobre 2013), by Jean-Paul Sevestre, in Fontanes in the French departement of Lot (Midi-Pyrénées).

3. "Bernina" sewing machine	4. Table and great workspace
5. Nylon rods - joncs	6. Ribbons
7. Panels	8. Rib templates (using A3 mosaic)
9. The work of sewing, progressing step by step. Sooner than we can imagine, will be completed!	10. Details of semicircular and reinforcements in the "V" anchor points.
11. Construction of the risers (6 mm dyneema rope)	12. Dyneema risers "A" "B" and "C"
13. All lines and risers finished, and ready to mount on the wing!	14. First test (2-10-2013) !!!

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.
