7) Will Fancraft™ replace helicopters?

No.  Fancraft™ will be integrated as a compliment to existing helicopter fleets.  The relationship of Fancraft™ to helicopters is similar to the relationship of helicopters to fixed-wing aircraft.  Helicopters didn't replace fixed-wing aircraft but they did extend the reach and capabilities of aviation.  Fancraft™ will do something similar.  They won't replace helicopters but they will expand the aviation envelope by making it possible to fly in airspace that even helicopters can't access.
