Default VTOL version of the Sparrow Hawk?

Based on the tilt rotor designs of the past I see many issues making
this idea work. 8 motors at what weight? Where are the batteries?
I don't think the is anything other than a pipe dream.


I saw the unpainted prototype in one of Windward Performance's hangars
over a year ago. The motors are small, very high output (a Joby
specialty), and the propellers are carbon fiber - very light. It's not
really a "tilt rotor" in my understanding, but a tilt wing with normal
motors and propellers (not rotors). Tilting small propellers is a lot
different than tilting big rotors.
