If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Valkyrie by Bright Star Gliders, you can supplement his card by adding your comment or write to us :
The photos you have are of the Bill Wolf designed Valkryie. He was from Indiana, USA. This wing form strongly resembled that of its contemporary, the Eipper-Formance Quicksilver , however without any tail section and a pronounced reflex airfoil on the Valkyrie. Your notes that this is a Bright star model is incorrect, Bright Star's Valkyrie is a much more sophisticated and newer design.
After starting hanggliding in summer 76 on a 80° Rogallo we built a Valkyrie in spring 77.
We started with just the construction plan. It was easy to build ( even as the first homebuild ), especially the sail.
But one big disadvantage : it could not be completely disassembled, only folded in half..Therefore we had to build a special car roof rack.
For me, the transition from the 80° Rogallo to the Valkyrie was too much, pitch control was way more sensitive. My brother had no problems..
In summer 77 during the Lilienthal Meeting at the Wasserkuppe, two officials were discussing the airworthyness of our Valkyrie. Finally, one remembered Otto Lilienthals last words, and the OK given..He won a prize for his nice performance.
Only 3 months after the first flight of the Valkyrie, our next glider, the Rhoenadler was ready for takeoff..
It is rather grateful for the help in this question, can, I too can help you something?
It is a pity, that now I can not express - it is compelled to leave. But I will return - I will necessarily write that I think on this question.
Between us speaking, I advise to you to try to look in google.com
