38mm RC Spinner for D3.0mm Shafts - TY1 HS7728R  [HS7728R]

38mm nose spinner for D3.0mm motor shafts

This 38mm spinner is an RC electric motor nose cone engineered to accept D3.0mm motor shafts. It acts as a replacement or upgrade for models built around a 3.0mm diameter shaft mount, and is supplied in a red finish to match your model's look.

Fit depends on shaft diameter: the spinner is intended for use with motors that have a D3.0mm shaft. Confirm the shaft size before fitting and make sure any prop adaptor or collet used matches both the shaft and spinner bore to prevent poor fit.

Fitting notes: slide the spinner onto the motor shaft or prop adaptor, align it so the spinner runs true to the shaft, then tighten using your model's prop nut or retaining hardware. Perform a runout check at low throttle and bring up speed gradually; correct any misalignment if vibration appears.

Role in tuning and maintenance: the spinner tidies the nose profile and centralises prop mounting. It is commonly used during maintenance cycles to restore correct fit and appearance on electric models.
