Gator RC CNC Aluminum 3D Spinner

The Gator RC CNC Aluminum 3D Spinner is a precision-machined aluminum spinner designed for popular 50cc–55cc class gas engines, including HP-50, DLE55, DA50, and JC51. Available in Silver or Gold, this spinner adds a clean finished look while providing durable aluminum construction for RC gas aircraft.

Machined from aluminum alloy, this 3D-style spinner is a great replacement or upgrade option for sport, aerobatic, and scale aircraft using compatible gas engines. This spinner features a verified, ultra-light weight of only 36.17 grams (1.28 ounces) to keep your airframe nose properties highly balanced.

⚙️ Verified Engine Compatibility:

Engineered to match the bolt patterns and hub spacing of standard 50cc–55cc class RC gas aircraft power systems:

  • DA-50 / DLE-55: Drops cleanly onto industry-standard single-cylinder gas engines.
  • HP-50 / JC51: Direct mechanical fitment parameters across matching crankshaft hubs.
⚠ Sizing & Clearance Note: Sized precisely at 41mm x 41mm x 26mm. Always confirm your cowl profiling and propeller hub thickness before final assembly to ensure optimal backplate spinner clearance and no friction rub.

💡 Modeler’s Tips

When installing aluminum spinners onto gas engines, always check that the prop cutouts are large enough for your specific propeller blade root without binding or pinching. If you are using wide-blade carbon or thick wood propellers, you can gently expand the aluminum spinner slot using a fine round metal file or dremel sanding drum before balancing.
