Yup, Stefan Raab is kind of crazy. He also invented the wok world champion ship. Imagine racing down a bob sled run in a wok.
And who was the first pilot to try it ?
I would think it was Charly Zimmermann. He was twice helicopter freestyle world champion. There is a video available (29.95 Euros).
I would like to see nick lappos comment.
I have no sound on my PC, who was the pilot?
