Coaxial Rotor System: the future of helicopter design?

Does anyone remember the Kammand Helicopter the K-max? Small,Twin rotor, awesome design for heavy lifting.

The Navy looked at it (to replace the H-47 for ship to ship resupply) but it never happened. Even thought it was a much better design than was being used, taking up much less space than the larger H-47, it just did not happen.

I am unsure why. Politics? Range?

Can you autorotate a helicopter of this design?

Can you autorotate a helicopter of this design? I think the aswer is yes, although there is no need to have contra rotation on an auto gyro, as there is no counter rotation on the fuselage. The whole reason to have contra rotation is to do away with the tail rotor. Another benefit is a smaller rotor diameter.
