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

38mm spinner built for D3.0mm motor shafts

This 38mm spinner is an RC-scale electric motor nose cone made to fit D3.0mm motor shafts. It functions as a direct replacement or an upgrade for models that accept a 3.0mm diameter shaft mount, and comes in red to match your model's styling.

Fit and compatibility depend on the shaft diameter: this spinner is intended for use with motor shafts measured at D3.0mm. Verify shaft size prior to installation and ensure any prop adapter or collet used matches both the shaft and the spinner bore to prevent fitment issues.

Installation notes: slide the spinner onto the motor shaft or prop adaptor, align the spinner so it sits concentric to the shaft, then secure it using the model's existing prop nut or retaining hardware. Check runout at low throttle and increase rpm carefully after fitting; correct alignment if vibration or imbalance is detected.

Tuning role: the spinner offers a tidy nose profile and centralised mounting for props or adapters, and can serve as a service replacement during maintenance to restore correct fit and appearance.
