RUN TIME
The largest factor in run time is the capacity of the battery pack. A larger mAh rating
increases the amount of run time experienced.
The condition of a battery pack is also an important factor in both run time and speed.
The battery connectors may become hot during driving. Batteries will lose performance
and capacity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries
and electronics over time. Sudden acceleration will also lead to shorter run times.
TO IMPROVE RUN TIMES
• Keep your vehicle clean and well maintained.
• Allow more airflow to the ESC and motor.
• Change the gearing to a lower ratio. A lower ratio decreases the operating temperature
of the electronics. Use a smaller pinion gear or larger spur gear to lower the gear ratio.
• Use a battery pack with a higher mAh rating.
• Use the optimum charger to charge battery packs (Visit your local hobby dealer for
more information).
PRECAUTIONS
• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
GEARING
Your vehicle has been equipped with the optimal gearing for the stock platform. It offers an
ideal balance between speed, power and efficiency. Should you decide to customize your
vehicle with optional batteries or motors, it may be necessary for you to change the pinion or
spur gear.
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 “overgear” 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 tempera-
tures are too hot, a different gearing combination with a lower pinion gear and/or higher spur
gear is suggested.
CHANGING THE PINION GEAR/GEAR RATIO
The Super Baja Rey uses a motor mount with pre-set gearing from 16-24T.
1. Remove the lower motor mount chassis plate, the motor, and motor mount.
2. Loosen the set screw and remove the installed pinion gear.
3. Install the motor screws corresponding to the number of teeth on the pinion gear.
4. Place the new pinion gear on the end of the motor shaft, so the setscrew is located over
the flat of the shaft.
5. Position the pinion gear so that the teeth line up with the spur gear and secure the pinion
gear by tightening the set screw.
6. Check the gear mesh to ensure that everything spins properly.

SETTING THE GEAR MESH
The motor gearing is set on the motor mount and uses corresponding holes that match the
number of teeth on the pinion gear. The gear mesh has already been set at the factory. Setting
it is only necessary when changing motors or gears.
Proper gear mesh (how gear teeth meet) is important to the performance of the vehicle. When
the gear mesh is too loose, the pinion gear can damage the spur gear. If the mesh is too tight,
speed could be limited and the motor and ESC will overheat.
IMPORTANT:
The included 19T pinion gear is suitable for use with a 6S Li-Po battery.
NOTICE:
For extreme load surfaces (e.g., sand and tall grass), gear down 1–2 teeth
on the pinion gear to minimize the chance of motor and ESC damage.
POWERING OFF THE VEHICLE
1. Power off the ESC.
2. Power off the transmitter.
3. Remove and charge the batteries.
