Here's the latest entry into the wonderful, whacky world of new aviation concepts.
Verticopter: an innovative and realistic approach to VTOL.
Look at the performance section - the smallest manned (sorry - peopled) version has two 250-C20R engines, and carries 2 people. Twice the power as a Jet Ranger for the less than half the payload. But it goes fast!
Note that there is quite a lot of discussion to CG management - no wonder!
Anyone care to rate it's chances of ever getting to the full sized prototype???
