Gator-RC Large Threaded Propeller Hub
Add a clean, finished look and professional performance to your large-scale aircraft with the Gator-RC Large Prop Hub. This robust unit is designed for heavy-duty gas engines, featuring a high-quality threaded "screw onto backplate" style installation. Precision-machined for durability, this hub provides the strength needed for high-vibration environments while maintaining a sleek, scale appearance.
⚙️ Robust Backplate Design
Unlike standard prop nuts, this hub utilizes an 8.5mm thick backplate for maximum surface area and security. The threaded design allows the hub to screw directly onto the backplate, creating a seamless and secure attachment for your propeller and spinner assembly.
Key Features
- Precision Machined: Engineered for reliability and a high-gloss, professional finish.
- Heavy Duty Construction: At 5.7 oz, this unit is built to withstand the torque and vibration of large-displacement gas engines.
- Easy Installation: Features a 11mm center hole in the backplate, compatible with a wide range of large engine crankshafts.
- Scale Appeal: The 72mm length provides a perfect visual transition between the propeller and the engine cowl.

💡 Gator-RC Modeler’s Tip: Proper Seating
When installing a backplate-style hub, ensure your propeller hub is clean and free of debris. Tighten the assembly to your engine manufacturer's torque specifications to ensure the backplate seats perfectly flush against the drive washer, preventing unwanted vibration.
