💡 What is a pinion gear used for in RC cars?

Pinion gears transfer rotation from the motor to the drivetrain, setting speed and torque. - Transfers power from motor to drivetrain to tune speed and torque - Works best with correct module and bore to ensure smooth mesh - Stainless steel gives durability under high RPM and load - Pair with the matching spur gear to avoid mesh issues
