Great! Thanks for the additional info, Tony.

Yes, I'm a great believer in ribs or battens supporting the airfoil shape at low angles of attack.

It would be great if someone would take on the project of recreating what you have done here.

A truly portable hang glider. 30 years later the patent has wore off.

4 photos ebay brochure.

I was looking for the short pack project and this is as close as I could get. (Move it Bob if you know where.)

There was no mechanical patent.
There was simple copyright on the document "plan".
