Are you interested in advancing  your 2 place VTOL concept. I would,

This is the way to do a tilt rotor: http://bellv280.com/
The transmission pivots the rotor instead of the whole drivetrain. On a
small aircraft, the cross shaft would be driven and angle drives would
drive
the rotors.  The rotor shafts would be hollow for control rods to the
rotors.  This has been done before, check this out:

I saw this aircraft at Wright Patterson.

These aircraft are more difficult to fly because one rotor can get in a ring vortex state
causing the aircraft to roll over. That has happened several times in the V22.

One rotor is safer.
