Your vehicle has been equipped with the optimal gearing installed for the use of a 3 or 4S battery. It offers an ideal balance between speed, power, and efficiency. Installing a  pinion gear with fewer teeth or a spur gear with more teeth will provide greater torque but will reduce top speed. Likewise, a pinion gear with more teeth or a spur gear with fewer teeth will reduce torque and increase top speed. Care should be taken when installing larger pinion gears as this can “overhear” the vehicle, resulting in overheating of the motor and ESC. When testing different gearing options, pay close attention to the temperature of the motor and speed control to ensure you are operating within the temperature range of the components. The motor or ESC should never be so hot that it cannot be touched. If temperatures are too hot, a different gearing combination withlower pinion gear and/or higher spur gear is suggested.Adjusting the gear mesh

  1. Remove the two screws holding the motor to the mount.
  2. With your chosen gear installed on the motor shaft, select the pair of motor mounting holes that allow for the tightest gear mesh without having to force the gears together or forcing the motor holes to line up with the mount.
  3. Install the two motor mounting screws and washers. There should be just enough space between the pinion and spur gears that a small piece of paper can be rotated between the gears easily. If the paper is difficult to rotate into the gears, remove the mounting screws and rotate the motor to the next set of mounting holes. Re-install the mounting screws.
  4. Remove the paper. Check the mesh at 3–5 different locations around the spur gear for a small amount of movement.
