3. NOTES:
7th march 2010
 LEparagliding 1.0 software completed
21th march 2010
 Working in the location of materials for the first prototype. Construction should begin soon :-)  !!!
26th march 2010
 Visit the ateleir that will make the whole wing assembly. More information coming soon!
10th april 2010
 Construction start...
6th juin 2010  
Almost 10 cells already built. Everything is progressing well. We are going slowly, because among the
regular work and the paragliding competitions, there is little time for gnuLAB2!
16th july 2010
 Right wing completed !!!
17th august 2010
 We are sewing special risers for initial AoA adjustment
23th octobre 2010
 First inflations, Sant Boi (Barcelona)
24th octobre 2010
 Test flights in training hill in Avià (Berga)

4. CONSTRUCTION
Photo report of the gnuLAB2 construction

The construction of this proto being so collaborative. The design, pattern making, and cutting of the tissue is being done in Teià, in the Laboratory, and the assembly of all panels, profiles, anchorages, reinforcements, and the suspension lines, was being done in the paragliding workshop STRIP-AIR in El Prat de Llobregat (Barcelona). The design and construction of a new paraglider prototype is not easy and we must find the best synergies!
