Finish off the nose of your plane with a nice 40mm (1.57 inch) aluminum spinner! These spinners are made from top quality aluminum and have a nice polished finish. They feature a collet style retainer, so they slide right on your motor shaft easily and clamp down firmly when the prop nut is tightened.

This spinner is designed for smaller motors with a 3mm motor shaft. See the photo below for complete measurements of the spinner.
