TY1 HS75102W 102mm Prop Spinner, Aluminum Back Plate (White)  [HS75102W]

102mm propeller spinner featuring an aluminum back plate

The TY1 HS75102W is a 102mm RC prop spinner finished in white and paired with a machined aluminum back plate to stabilize the mounting interface. It suits model aircraft that benefit from a solid rear plate to hold the propeller and smooth the nose profile.

Fitting is aimed at hobby technicians: confirm the prop adapter and shaft measurements, place the aluminum rear plate against the prop hub, align the spinner shell, and secure with the model's screws or compatible adapters. Check that the spinner sits concentrically and clears the cowling before the first power test.

During setup include the spinner when balancing the propeller; a correctly seated spinner reduces vibration and eases final trimming. Periodic checks should include screw security, visible distortion of the plate, and a brief run-up to ensure concentric rotation.
