Battery choice and gearing determine the speed of your model. The following gearing options cover Traxxas Rustler,
Bandit and Stampede models. For other applications, refer to the model manufacturer’s documentation.
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 ratio
(numerically lower) to increase
top speed. When using higher
gear ratios, it is important to
monitor the temperatures of the
battery and motor. If the battery is
extremely hot, and/or the motor
is too hot to touch, 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.
# Spur Gear Teeth
x 2.72 = Final Gear Ratio
# Pinion Gear Teeth
Use the following formula to calculate the overall ratio:
Speed
Bandit 35+mph 45+mph 65+mph 70+mph
Rustler 35+mph 45+mph 65+mph 70+mph
Stampede 30+mph 40+mph 60+mph 65+mph
