Exactly. VTOL is also great as you can deliver the blades really close to construction location. If you installed small props at the tips of the blades, you wouldn't need any torque rotor. I don't know if you still need the variable pitch mechanism or could you lock the blades to one pitch for spin-transport. Helicopter efficiency is quite terrible though so long distance travel would require constant aerial refueling. I guess you could have a probe in the hub. What could go wrong?
