Pretty cool! I've made some sketches over the years trying to accomplish
something similar with the canard configuration. I had one drawn up with
three turbofans, vectored thrust on the two rears, and the front one
only vectored downward and shutdown in forward flight. Another one with
large open props. Paul you might still have some of my old 3D sketches.
More recently I saw a program on the Osprey, got me thinking about it
again. I was thinking of making a mini-Osprey with a more conventional
(non-canard) layout with a Bonanza v-tail.

No doubt about it the V22 is faster than a ducted configuration.

Here is a somewhat conventional helicopter rotor that retracts
like a prop on a motor glider.
