Hi all! Complete newbie here, working on my first beetleweight. Only ever done RC cars and planes before, which is simple compared to this! I have come up with a rough idea of how the spinner on my beetleweight will be mounted, but just wanted some feedback regarding strength and balance. I have got a rough sketch that I have just knocked up in MSPaint (work PC doesn't have anything better on it). This will be a vertical spinner.

Red is the blade itself.
Blue is the hub, which I will turn out of aluminium, and the blade will be bolted to.
Grey is the bearings.
Orange is the spindle.
Green is the pulley (belt driven) which will be fixed to the hub from the other side.

Picture is not anywhere near scale. First impressions? If its complete junk, say so and I will go back to the drawing board
