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.
One morning in Chattanooga in 1977 as I laid in bed in the pilots bunkhouse, I listened to Chuck Toth (who ran the hang gliders motel) haggling with someone attempting to sell his yellow Cumi 10. A year later I met that pilot flying West Rutland and shared many a thermal with him. The Cumi-10 was gorgeous and seemed to thermal very well.
