I'm familiar with the Terrafugia and other recent "flying car" developments.
I'm also developing my own concept with a possibility of collaboration. What makes my concept unique among others is the mechanical simplicity and high performance. It is as simple as conventional airplane so giving the same high performance, great fuel efficiency, and low operational cost. But with the added benefit of being able to land and take off from anywhere a helicopter can in a much more compact package than either an airplane or a helicopter.
