Will these ever be made available in North America? Do coaxial rotor helicopters autorotate?

What would be the advantage of a coaxial setup?

No tail rotor to fail or get caught in the bushes. Probably shorter in length than a tail-rotored heli too. Need less room to land and safer for people and obstacles on the ground when you get there.

 

No tail rotor means more power available for lift. I'm guessing more maneuverable as well.

 Having the rotor(s) over the cargo area increases the CG range as well.

The Kamov range is known for its lifting abilities, though its rotor head and mast is a lot more complicated than this demo model.

 

The lower rotor works in descending airflow, so is a bit less efficient.
