This is what the picture looked like to me. Maybe this is the trial of Ian's "High speed electric actuators". Maybe the resolution is just too poor, but i wondered about that cable.

rigid rotors for your objective is that the craft should perform as an airplane if it stalls. In other words, if there is sufficient elevation, the nose will drop and RRPM will then increase.
If a heli rotor stalls you fall from the sky like a stone - there is NO mode of recovery. The only way to avoid this would be designing a "pushable" collective for -ve pitch to force rotation (like windmilling a prop).

At the serious risk of threadjacking an already interesting subject:
I am a believer in identifying the problem before attempting to design the solution. Coaxial is the most flexible system but intermeshing has hub packaging and possible shaft weight advantages. I champion neither, but recognise both as solutions to the problem of high speed heli flight. Remember my interest here has always been to identify the technological lmlitations of future helicopter development.

All fellow Rotorheads,
Have a Merry Xmas, and thank you for developing my understanding of rotorcraft!!!
