What is this?
The RC Hardened Gear is commonly used in remote control (RC) models, such as RC cars, trucks, boats, and drones. It is used to transfer rotational motion from the motor to other components, such as the drive shaft or spur gear, allowing the model to move forward or backward.

Are there any advantages of the product?
The pinion gear is made of aluminum 7075, which is durable and wear-resistant. It can effectively resist deformation.
It provides smoother and more efficient power transfer from the motor, resulting in improved acceleration and top speed.

How to use it?
Steps of installation: 1. Slide the RC Hardened Pinion Gear onto the motor shaft; 2. Align the teeth with the corresponding gears it will mesh with (such as the spur gear); 3. Ensure that the gear is securely seated on the shaft.

What should I notice?
Please check if your spur gear and pinion gear have the same pitch, otherwise the teeth won't mesh.
