1. DESCRIPTION

Swoop
Figure 4. Colors division

Swoop parakite is a 6.10 aspect ratio, 50 cells, true three-liner, reflex parakite (new gnuReflex airfoil). Developed jointly by Pere Casellas and Tim Weber. Prototype no. 1 is currently under construction by Tim Weber. Plans available in initial size 18 m2.

The new airfoil gnuReflex.dat gnuReflex.txt was derived from "candidate 1" of gnuReflex project (completion soon).

Prototype number 1 is under construction (Tim Weber, Germany https://www.instagram.com/thermik_timmy/). We will update documentation progressively.



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.
