I want to build a Super-Puma helicopter in city minifigure scale and form, I have the basic design planned, but I am not familiar with any five-sided technic connectors, which I will need for the rotors.
I have thought of a potential idea, but it is still a little too large for city scale helicopters:
Any better ideas out there?
Update - I had this idea, but it is quite loose, maybe I could tighten it up by using PC dishes on PC sticks (PolyCarbonate pieces used together bind to each other).
I tried wrapping string round the pegs and they still wobbled, this one's tricky.
