If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Cumulus 10 by Eipper Formance, you can supplement his card by adding your comment or write to us :
I assembled gliders for Eipper in the late 70's and recognise this glider to be a Flex-III not a Cumulus-X. Nice picture though!

The Cumulus I have in storage has folding tubes for truncated wingtips. There are no battens, and the flying wires are adjustable for seated or prone. I'll send a picture.

Datu, you have a Cumulus 5

I correct myself. It is a Cum. 10. Very similar to a Flexi 3
Both Dave Cronk designs.
