This 38mm spinner is an RC-scale accessory intended to fit motors with a D3.0mm shaft and to give a finished nose profile for electric propeller setups. The translucent orange finish helps with visual alignment during pre-flight checks while keeping the component easily identifiable on the model.
Compatibility is driven by the shaft diameter: confirm your motor shaft measures 3.0mm and inspect for any shoulders or flats before installing. The spinner functions as both a cosmetic trim piece and an aid when balancing propellers and adjusting nose weight for flight handling.
Installation notes: make sure the spinner seats correctly on the D3.0mm shaft and that it clears any surrounding cowling or motor mount. Follow standard spinner mounting practice for your model and re-check balance after fitting a propeller or any adapter to prevent vibration issues.
