It's the Eurocopter X3
The only one on the site is this post from 7 years ago.
Im just curious.
Also this includes the Benoist Tractor
Other forgotten planes
Apollo Fox
SPAS 13 (Nothing really available on it)
This doesn't even have any pictures anywhere.
Ario 1
NASA's E-7
These forgotten planes come from the plane bible Click
Challenge excepted!
Probably because of how incredibly complicated and unheard of it is. Dont get me wrong, this be a lovely edition if someone built a good replica.
