It was first tested by remote controls but here is a manned test flight. I think the project was scrapped because the Wankel (devellopped by Citroen and NSU) had cooling problems at full blast and could not be certified..... What a pity!.

and this is the new Citroen concept car which is inspired by this helicopter!!!! Check out the contrast with the shape of the "Tube" (grey, square shaped van) in the background on the above Video!!! Time flies faster than anything else!

Wankels are very thirsty but do like to rev high from what I understand.
Shame this never got developed enough, looks like it was have been an interesting contender.
