D3.0mm Shaft 38mm Electric Spinner - TY1 HS7728TB  [HS7728TB]

Precise 38mm spinner for D3.0mm shafts

This TY1 HS7728TB spinner is sized to a 38mm nose profile and designed to mount on D3.0mm motor shafts. It serves as a lightweight cosmetic and aerodynamic cover for small electric models, concealing the prop adapter area while giving a clean nose shape.

Installation is simple on typical setups: slide the spinner assembly onto the D3.0mm motor shaft and seat it against the prop adapter or hub. Once fitted, confirm concentric alignment between the spinner, motor shaft, and propeller, then carry out a static balance check since small spinners can make minor propeller imbalances more apparent.

Role and notes: the spinner mainly streamlines the nose and shields the adapter area and is not part of the powertrain. Pay attention to runout and balance when fitting, and trim or rebalance the propeller assembly if any vibration appears to protect bearings and electronics.
