Description

A 3.17mm RC Aluminum Bullet Propeller Adaptor Holder is a small yet essential component used in radio-controlled (RC) aircraft, drones, and other RC vehicles to securely attach a propeller to the motor shaft. Below are the key properties and features of this component:

Key Properties:

1. Material:
   • Aluminum Alloy: Made from high-quality aluminum alloy, which is lightweight yet strong, providing durability without adding significant weight to the RC model.
2. Shaft Diameter:
   • 3.17mm Bore: Designed specifically for motor shafts with a 3.17mm diameter, ensuring a precise and secure fit.
3. Propeller Compatibility:
   • Bullet Style Adapter: The bullet shape allows for easy installation and removal of the propeller. It typically includes a collet that tightens onto the motor shaft as the propeller is secured, ensuring a firm grip.
4. Secure Fastening:
   • Propeller Lock Nut: Usually comes with a threaded lock nut that secures the propeller onto the adaptor, preventing it from loosening during operation.
   • Collet Design: The collet mechanism ensures that the adapter remains tightly fixed to the motor shaft, even under high rotational speeds.
5. Weight:
   • Lightweight Design: The aluminum construction keeps the weight minimal, which is crucial for maintaining the performance and balance of RC models.
6. Corrosion Resistance:
   • Anodized Finish: Often features an anodized surface treatment to resist corrosion and wear, extending the life of the adaptor in various environmental conditions.
7. Ease of Use:
   • Quick Installation: Designed for easy and quick attachment or removal of propellers, making it convenient for users to swap out or adjust propellers as needed.
8. Application:
   • RC Aircraft and Drones: Commonly used in RC aircraft, drones, and similar models, particularly in electric motors where the shaft size is 3.17mm.

This adapter is a crucial part of the propulsion system, providing a reliable and secure connection between the motor and propeller, ensuring smooth and efficient operation of the RC model.
