Gator RC Carbon Fiber Spinner 75mm (3") FAI Flo-Thru 2-Blade
Designed for lightweight electric aircraft, the premium Gator RC 75mm (3") Carbon Fiber Spinner combines immense structural strength, incredibly low rotational weight, and advanced ventilation properties into a clean, FAI-style aerodynamic package.
The carbon fiber cone features pre-cut 2-blade propeller openings and CNC-machined flo-thru cooling slots that allow air to pass directly through the spinner hub. This engineered ventilation path maximizes motor and ESC thermal dissipation while keeping your nose-weight profile balanced. At only 22 grams (0.78 oz), this spinner is an excellent choice for F3A pattern aircraft, precision aerobatic models, sport electric airplanes, and other applications where minimizing nose weight is important.
🚀 Target Applications:
- F3A Pattern competition aircraft demanding minimal gyroscopic weight factors
- Precision Aerobatic models and lightweight competition builds
- High-power sport electric airplanes requiring enhanced powertrain cooling airflow
Key Features
- Flo-Thru Ventilation Slits: Precision-milled cooling slots channel high-velocity air directly onto your outrunner motor casing to lower running temperatures under heavy flight loads.
- Ultra-Lightweight Mass: Tips the scales at a mere 22 grams (0.78 oz) to significantly lower rotational inertia and optimize electronic speed control braking response.
- FAI-Style Aerodynamic Profile: Features a shorter, streamlined parabolic shape that complements many modern pattern and aerobatic aircraft designs while maintaining a clean appearance.
- CNC Machined Backplate: Precision-milled aluminum backplate prevents spinner runout and guarantees true concentric rotation at extreme RPM levels.
- Factory Pre-Cut Openings: Arrives out of the pack with matching pre-cut openings tailored for standard 2-blade electric propeller profiles.

💡 Modeler’s Tips & Installation
Because this FAI spinner features pre-cut blade openings, verify that your specific electric propeller hub sits cleanly within the slots without binding or rubbing on the carbon fiber raw edges. If you are using an extra-wide root carbon or thick wood prop, you can carefully dress the opening edges using a fine round diamond file or a low-speed dremel sanding drum. Always re-check the balance of the entire spinner and propeller assembly as a unified module on your balancer before your maiden flight.
