Gee I don't see why helicopter maintenance is so pricey  :)

Here is almost a complete articulated counter rotating rotor head.
I can see why counter rotating rotor head helicopters are so rare. I still
haven't figured out how to move the forward swash plate yet. I am thinking
Blue Tooth radio controlled :) Four high speed, computer radio controlled,
angular electric servos, one on each blade, would do the trick.
It would vastly simplify this and make fly by radio control a real reality.
It could also be done with a infra red optical link.

Another possibility is control the swash plates with three servos each.
The servos would not have to be as fast.

Perhaps the control rods can go into the inner shaft for the front
rotor. About the only company in the world that could build this is Kamov.

It is also still laking the lagging and flapping hinges.

I am not dumb enough to try to build one of these :)

I think I read that the control input to the rotor has to lead by about
90 degrees? The top and bottom rotor then have to lead from
opposite directions.
