This 38mm spinner is an RC-scale accessory designed to fit motors with a D3.0mm shaft and provide a finished nose profile for electric propeller setups. The translucent orange finish helps visual alignment during pre-flight checks while keeping the component clearly identified on the model.
Compatibility centers on the shaft diameter: confirm your motor shaft measures 3.0mm before installation. The spinner serves as a cosmetic and aerodynamic trim part, and it plays a role during tuning when balancing propellers and adjusting nose weight for flight behaviour.
Installation notes: ensure a proper fit on the D3.0mm shaft and verify the spinner clears surrounding cowling or motor mounts. Use standard spinner mounting practices for your model type and re-check balance after attaching any propeller or adapter to avoid vibration issues.
