If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Zephyr by Pacific Kites, you can supplement his card by adding your comment or write to us :
Aloha, in 1978-79, I flew a Green-n-White 1976 Zephyr, Delta/Rogallo wing...training in Addicks Resevoir/Dam in HoustonTx(35ft), then SomervilleTx(180ft?), and then Packsaddle Mountain near BurnetTx(420ft..or there abouts). I sadly lost the kite long ago and never replaced or flew again, but I remember it had 10 battons,and a brick-like glide ratio of 7-1,
with "I think" an 18ft length and 21ft wingspan, and weight of 45 lbs.
It's been a long time, and I'm really only sure of battons and glide-ratio...but I hope this helps!
Thanks for tha memories!
