FREE FLIGHT WINGS DESIGN STUDIO


March 2026, first Swoop 18 proto #1 flight tests. The planned calage seems correct (30%). With fixed risers everything seems correct. Speed ​​and performance is good. Wingtip stability correct. With parakite risers we still need to find the maximum and minimum flight AoA.

Development of LEparagliding.
Section 27, optional wingtip type "2" with a generic parabola of degree n, and others.

Version 3.27.1 of lepg (GUI) has been released by Stefan Feuz and can be downloaded from here:

The expoLAB2025 exhibition took place on September 20, with a deliberately private feel. It marks a milestone in the history of Laboratori d'envol. After three complicated years for me (2023, 2024, 2025), with a low production of designs and software, in October the Laboratory will move definitively to Les Escaules. I sense a new stage with new ideas and the desire to fly high again.
