Gemfan 75mm‑A White Hollowed Spinner with Aluminium Backplate – Lightweight RC Aircraft Spinner

Gemfan 75mm‑A White Hollowed Spinner with Aluminium Backplate – Lightweight RC Aircraft Spinner

The Gemfan 75mm‑A hollowed spinner is engineered for pilots who want a strong, lightweight, and accurately balanced spinner for their RC aircraft. The white nylon cone is hollow‑carved to reduce weight and enhance cooling, while the CNC‑machined aluminium backplate provides excellent rigidity and vibration‑free running. At only 50g, it offers a noticeable reduction in nose weight compared to solid spinners, improving handling and efficiency.

This 75mm‑A version uses the flat‑bottom style commonly fitted to electric aircraft, ensuring easy installation and consistent alignment. The hollowed design promotes airflow around the motor, helping maintain cooler operating temperatures during extended flights.

To ensure compatibility with a wide range of propellers, the spinner includes four prop rings, allowing you to match different hub diameters cleanly and securely.
