UH-1's will autorotate fantastically, long as you keep the energy up. That's the advantage of those fuckhuge mains.  But once they slow down past a critical point (coffin corner) you're falling.

How are they planning on dealing with retreating blade stall

With a single disk, the problem is balancing lift on both sides where one is advancing and the other retreating. The retreating has to have a higher AoA to compensate, and therefore stalls first.

With contra disks, you can have a different swashplate for each rotor set. The retreating blades on each side can get a 0 AoA and therefore wont stall.
