Gearing

What is Gearing?

There are 2 Gears on your car that you need to worry about changing: the Spur Gear and the Pinion Gear. The Pinion Gear is the one attached to the motor.

Changing the Pinion or Spur Gears will result in much different results.

On the Pinion Gear, the higher the number of teeth, the faster (top end) your car will have, but you will lose acceleration. The lower the number of teeth, the faster your car will accelerate, but you will lose top end. More top end usually results in less run time, also.

On the Spur Gear, the higher the number of teeth, the more acceleration the car will have, but the less top end. The lower the number of teeth the more top end you will have, but you will lose acceleration.

It is normally easier to change your Pinion Gear than to change the Spur Gear.

How do you change the Gearing?

The Pinion is changed by loosening the screws to the motor (to let it have some adjustment) and then removing the Pinion. Slide the new Pinion on and re-adjust the Gear mesh.

To change the Spur requires a little more work. Depending on the vehicle you own, it could be as easy as removing 2 screws or disassembling a whole portion of the car.
