Could it be that a single rotor solution would be much less complex and much cheaper?
That's sort of my opinion on it too. It's an interesting concept, but it just doesn't seem like a great solution to the problem. It seems like a tandem rotor heli, or a coaxial is just a cleaner solution to the problem.
I looked at this thing a while ago. It's interesting, but I don't think it's the best solution to this problem. This makes more sense to me:

Or there was another one I've seen, can't remember the name, but it's a single main rotor, but with two anti-torque rotors. The AT rotors are mounted on the sides, not the back. They push in opposite directions in a hover, to counter torque. But in forward flight, they both push forward, just one side more than the other.
