Thanks all for varying inputs but James hit the nail right on the head - exactly what I was conceptualising the control would be to have as Brian mentioned a propeller prop but with varying sections of tight and loose twists to make a complex helicoid as mentioned.

Would be great to have a play with the NODE let me know if you need anything from my end.

The wealth of knowledge in this forum is deep and drawing from various pools making MOI one of the sharpest tools in the kit.

Amazing result.
