If I understand correctly what you've said Dave, the area at 75% of the span is twisted by some kind of torque tube or bar that extends inboard to the blade root. When twisting this torque tube in one direction it will wrap/twist more at the root than at the 75% point….the longer this distance is, the more it will wrap. When used on a relatively short prop blade, the blade will be stable because it twists the blade in one direction, but a rotor blade will be twisting and wrapping both in positive and negative directions…twice per rev. I very well could be all wet, but I can imagine it would be difficult to precisely control this blade. I'm not saying this can't work….just that I can't imagine how to make it work.
One must be careful using carbon cloth….bend it beyond its min bend radius and its fibers will easily break….I am way too clumsy to use that stuff on aircraft .
