TY1 HS7728TB 38mm Electric Spinner for D3.0mm Motor Shaft (Trans. Blue)  [HS7728TB]

38mm electric spinner for D3.0mm shaft

This TY1 HS7728TB spinner is an RC-scale nose spinner sized for a 38mm diameter profile and specified to mount on D3.0mm motor shafts. It is intended as a lightweight cosmetic and aerodynamic cover for small electric models, providing a clean nose profile while concealing the prop adapter area.

Installation is straightforward for common model setups, slide the spinner assembly onto a D3.0mm motor shaft and seat it against the prop adapter or hub. After mounting, verify concentric alignment with the motor shaft and propeller, then perform a static balance check; small spinners can reveal or amplify minor imbalances in the propeller assembly.

Tuning role and notes: the spinner mainly streamlines the nose and protects the adapter area, it is not a powertrain component. When fitting, pay attention to runout and balance, and trim or balance the propeller assembly as required to avoid vibration that can affect bearings and electronics.
