The spinner is molded plastic paired with a machined aluminum base to provide a lightweight cover that improves appearance, protects the prop hub, and supports stable rotation. Key benefits Cleaner airflow and reduced hub exposure: the enclosed spinner helps smooth airflow at the prop root and reduces debris contact with the prop hub. Durable and lightweight construction: plastic spinner keeps weight low while the aluminum base provides secure mounting and improved strength where it matters. Better balance and reliable rotation: the matched spinner and base reduce vibration when properly installed, improving flight smoothness and motor loading. Easy size selection: available in multiple diameters to fit a wide range of twoblade propellers and model styles.
