Fed Ex just called ... they want to know how many Super Priority mail packages each of these solar-pumped beauties can carry and also what the max air speed is?
Thanks for the post.

The trick is to get enough area exposed at roughly the correct angle to the sun. I think speed will have to be kept low to keep wear on the sail-like solar panels reasonable.

I have a private pilot's license and am planning to take up soaring after I finish Volume 3 of my science fiction series. In Volume 2, gliders are essential for the heroes to defeat the Forces of Evil.
