Beppe,
Here's me and my Orion around 1962. It was on reeds. I never flew it because of college commitments. I understand they were great fliers. The image of me with the Curtis A12 was taken a few years ago. Dan.

handglider,
I wish I could help you. I would love to see a squadron of these flying around since mine looks so great up in the air. Unfortunately the plans I draw up are really crude and just enough to get me going. They are also drawn in AUTOcad. A software that is expensive and generally not used by us hobbiests. Dan.
