Gator RC Flow-Thru Spinner
Give your RC airplane a clean, finished appearance while allowing cooling air to reach the power system. The Gator RC Flow-Thru Spinner features a durable molded plastic cone with angled ventilation slots and a lightweight CNC-machined aluminum backplate.
The slotted, pitched backplate works with the openings in the spinner cone to direct air through the spinner. This makes it particularly useful for electric-powered aircraft where additional airflow around the motor can help with cooling.
Available in six diameters and five colors to fit a wide range of sport, scale, and aerobatic RC airplanes.

Selecting the Correct Spinner
Choose a spinner diameter that matches the diameter of your airplane’s cowl or nose ring. Confirm that the backplate center hole, overall spinner length, and propeller openings are suitable for your particular motor, engine, propeller, and adapter before installation.
Important: Propeller opening requirements vary. Some installations may require careful adjustment of the openings for proper propeller clearance. Check the spinner, propeller, backplate, and mounting hardware for secure fit before every flight.
Package includes: One spinner cone with aluminum backplate and associated spinner assembly hardware.
