City scale connection for five-bladed helicopter rotors 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.
5-fold symmetries are difficult to build in LEGO, especially at small scale. Here is an attempt, still a bit bulky...
