💡 What is a pinion gear used for in RC cars? Pinion gears transfer power from the motor to the drivetrain and help tune speed and torque for different tracks. - They determine the gear ratio with the spur gear for acceleration and top speed - They must match spur gear pitch and motor shaft size for proper meshing - After changing pinion sizes, monitor motor and ESC temps to avoid overheating
