I have recalculated the whole project of the Asso X Jewel and redesigned it.
If anyone needs parts for it, please contact me. You can see the picture parts here:

All my drawings are made in Solidworks and the whole structural and aerodynamic calculation is made with Ansys.
I teach at the university and I have more then 30 thesis on this project.
There are so many errors on the original plans, that I wonder how people make it up to build it...

Anyway it's a great airplane.
