LEparagliding 3.15z
LEparagliding-3.16 "Z"
Full control to individually set the rotations of the profiles in space on three axes X,Y,Z and align the airfoils planes to te flow.
Read changes of version 3.16 here.

m
Airfoils 3D rotations in LEparagliding. Study of geometric transformations to rotate airfoils in three axes.
This improvement will be soon incorporated into the program code.

update
GG Hang Glider Update 2021-08-08: "Last Monday I moved the project to the farm of the aforementioned friend and on Thursday afternoon I was able to advance a little, (see attached power point) slide the sail over the leading edges and also make the keel pocket. It begins to encourage me to continue to be able to see the shape of the Rogallo.
In two more weeks - if I can- I return to the farm to continue to cut and assemble all the 3/32" SS tensioning cables."

BHL5 Basque
The BHL5-TA "Basque" wing is complete. Remains the trailing edge and lines (1-8-2021)


The models gnuA1, gnuA2, gnuA3, gnuA4 and gnuA5 reviewed and updated.
New set of lines with a calage of 25%. Added some new sizes.

gnuA6a-33 New project August 2021
