ProSpin spinners are made from high quality bar-stock for strength. They won't crack like cheap cast aluminum spinners do. ProSpin spinners are also 30% lighter than cast aluminum. All spinners include a shaft bushing, prop nut, and bolt. All spinners are polished.
Notes on Ordering:
1. Find out the size of the prop nut you need.
2. If you need a different prop nut, you need to order it separately.
3. Some engines, i.e. Saito engines, require a bushing that is larger than the nut.
A spinner caps the propeller hub for a clean nose line, and many of the pieces here double as prop adapters that mount the prop to the motor shaft. This category collects RC airplane spinners and adapter hardware sized mainly for electric power.
Aluminum Spinner and Prop Adapters
Aluminum precision spinner and prop adapter units are offered in several bore and length combinations, such as 32x2mm, 32x3mm, and 45x5mm sizes, to match different shafts and props. Their machined aluminum construction keeps the assembly balanced at speed.
E-Spinners and Replacement Parts
An MPI 50mm reverse-pitch E-spinner suits pusher and reverse setups, and a replacement collet, nut, and screw assembly is available for the 30mm RRC spinner. These keep an existing spinner serviceable rather than replacing the whole unit when small parts wear or go missing.
Match a spinner and adapter to your shaft and prop from the sizes here, checking the bore against your motor shaft.
