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

Spinner, 38mm diameter, for D3.0mm shafts

The TY1 HS7728TB spinner matches a 38mm nose profile and is specified for mounting on D3.0mm motor shafts. It provides an aerodynamic and cosmetic cover for the prop adapter region on small electric models and park flyers.

Fitting is straightforward: slide the spinner over the D3.0mm motor shaft and locate it against the prop adapter or hub. After installation, confirm concentric alignment and carry out a static balance check because small spinners can amplify slight propeller imbalances.

Notes on use: the spinner streamlines the nose and protects the adapter area; it is not a drivetrain element. During installation monitor runout and rebalance the prop assembly where needed to avoid vibration-related wear on bearings or electronics.
