MOTORS AND GEARING
One of the more significant advantages to your model’s
transmission is the wide range of available gear ratios. Changing
the gearing allows you to fine tune the speed of the model and
control the temperatures of the battery pack and motor. Use a
lower gear ratio (numerically larger) to reduce current draw and
temperatures. Use a higher gear (numerically lower) to increase top
speed. Use the following formula to calculate the overall ratio for
combinations not listed on the gear chart:
When using higher gear ratios, it is important to monitor the
temperatures of the battery, motor, and speed control. If the
battery is extremely hot (150°F) and/or the motor is too hot to
touch (180°F), your model is probably over-geared and drawing
too much current. This temperature test assumes that the model is
close to factory stock weight and operates freely with no excessive
friction, dragging, or binding, and the battery is fully charged and
in good condition.
This model is equipped with a 2000Kv brushless motor. The gear
combination that comes stock on each model provides good overall
acceleration and top speed. If you want more top speed and less
acceleration, install optional high speed gearing (more teeth). If you
want more acceleration and less top speed, use a smaller optional
pinion gear. Optional gearing not included.
Note: High speed gearing is intended for high-speed running on
hard surfaces and is not recommended for off-road or repetitive
starting and stopping. For this type of driving, smaller pinion
gears are recommended to reduce load on the motor.
