Aeronaut Spinners

There are two types of plastic spinners from Aeronaut. The first type has two self-tapping screws to hold the spinner cap on to the spinner. The back half of the spinner has slots to accept a rectangular section centrepiece. The slot is only 8m wide, in case you have a narrow bar centrepiece, but the walls of the spinner are thinned each side of the slot so that you can cut them out to take wider centrepeices (like the 12mm wide Aeronaut variety). You fit the prop to your prop holder first, then slip the back section of the spinner on next. You add the washer and prop holder nut and tighten the assembly. Finally you add the spinner cap. This type of spinner comes in three sizes.
