To achieve a good starting
point for the slipper clutch,
tighten the slipper clutch
adjusting nut clockwise until
the slipper clutch adjusting
spring fully collapses (do
not over tighten), and then
turn the slipper clutch nut
counterclockwise one full turn.

Do not run your model with
the slipper clutch adjusting
spring fully compressed. The
minimum recommended
slipper clutch setting is 1/2
turn counterclockwise from
fully compressed.

ADJUSTING YOUR MODEL

Motor and Gearing
One of the more significant advantages to your model’s
transmission is the extremely wide range of available gear
ratios. It can be geared low enough to run an extremely hot,
modified motor. A higher kV motor should be geared lower
(higher numerically) than a stock motor because it will reach its
maximum power at higher rpms. A higher kV motor that is geared
incorrectly can actually be slower than a correctly-geared, stock
motor. Use the following formula to calculate the overall ratio for
combinations not listed on the gear chart:

If you are worried that you might be over-geared, check the
temperature of the battery pack and motor. If the battery is
extremely hot, and/or the motor is too hot to touch, your model is
probably over-geared. If you are not able to run your model for at least
four minutes before the battery dies, then change to a lower gear
ratio. 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.

The model is equipped with a Velineon 3500 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 the included high-speed gearing (more teeth).
If you want more acceleration and less top speed, use a smaller
optional (not included) pinion gear. The included high-speed
gearing is intended for high-speed running on hard surfaces, and
this gearing 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.

Gearing Compatibility Chart
The chart to the left shows a full
range of gear combinations. This
does NOT imply that these gear
combinations should be used.
Over-gearing (bigger pinions,
smaller spurs) can overheat
and damage the motor and/or
speed control.
