This Great Planes' 1-Piece Black Nylon Spinner with Aluminum Backplate.|
Black nylon 2-blade spinner.
A sturdy aluminum backplate holds the spinner in round, which means
it turns truer, with less vibration.
The engine shaft hole is stepped from 5/16" to ¼", to perfectly
center the opening if enlarging is needed.
Spinners attach securely to backplates with the included screws.
One year quality guarantee.
