Red 38mm Electric Spinner for D3.0mm Motor Shaft - TY1 HS7728R  [HS7728R]

38mm spinner compatible with D3.0mm motor shafts

This 38mm spinner is an RC electric motor nose cone designed to mount on D3.0mm motor shafts. It serves as a direct replacement or upgrade for models accepting a 3.0mm diameter shaft mount, and is supplied in red to complement your model's finish.

Compatibility is governed by the shaft diameter: the spinner is intended for motors with a D3.0mm shaft. Confirm the shaft measurement before installation and ensure any prop adaptor or collet you use matches both the shaft and the spinner bore to avoid misfit.

Installation procedure: slide the spinner onto the motor shaft or prop adaptor, align it so it sits concentric to the shaft, then secure with the model's prop nut or retaining hardware. Check for runout at low throttle and increase speed cautiously after installation; adjust the fit if vibration or imbalance is noticed.

Effect on setup: the spinner provides a smoother nose profile and centralised prop mounting. It can be fitted as a service part during maintenance to restore correct appearance and mounting function.
