From that little video, you've got a jet engine in the back that has to act as both turboshaft and turbojet (thrust in forwrad flight once props are folded back ... or is that a turboprop/shrouded fan for thrust in forward flight?)
Is it clear whether or not the prop/rotor things electric drive or driven by that engine in the back.
Neat idea.
