💡 What is a pinion gear used for in RC cars and how to choose the right size?

Handy primer: Pinion gears transfer power from the motor to the drivetrain by meshing with the spur gear, and sizing affects speed and torque.

- It transmits power from the motor to the drivetrain by meshing with the spur gear. - The tooth count (24T-27T) sets gearing ratio, top speed, and torque. - 5mm shaft bore with M4 set screws makes mounting on 1/8 scale motors handy and secure. - Pair with the right spur gear to avoid tooth wear and overheating, while optimizing performance.
