The 1:1 scale Dash Wing was a project of love for Bob. Two Dash wings were constructed. The wings were intended to be strapped on the back of an adult. The wing is constructed of plastic. There is no mechanism to raise or lower the wings.
I came to own this wing pack when Bob offered it back in the early 2000s to the Micro community. The wings are as you see. I have not done anything further with them since I purchased them.
