Andy,
Sure is! It is pretty impressive that the new design concepts from Sikorsky are coaxial rotor designs. Like I said, it is definitely an interesting helicopter, but definitely not the world-beater that all of the comments on Youtube claim it to be. 100% of those commenting have no clue about helicopter capabilities, what is an impressive maneuver and what is a standard combat maneuver. I will say that nothing in any Ka-50 video I've seen is out of the ordinary for an Apache crew.
The Ka-50/52 is a step in the right direction as far as development potential, but the airframe design has severely limited the aircraft relative to attack helicopter capability. The fact that the gun is limited in traverse and elevation, the crew is side-by-side, it has retractable landing gear, and the pylons appear to be fixed in elevation are all factors that will severely limit its combat capability.
Still... it is an interesting step in the evolution of the Armed Helicopter!
