This Scale Moki Prop Hub Set is for your Moki S215, S250, S250-7 and S300 projects, cut from aluminum and hollow on the inside.

The included backplate will replace your Moki Prop Washer plate. You simply bolt it down just as you would bolt down the Moki Prop Washer Plate using the 6 M5 bolts, then place the spinner hub on top of it and use the included center bolt to install. Done.
