PrecautionS
»
Never touch moving parts.
»
Never disassemble while the batteries are installed.
»
Always let parts cool before touching.
adjuStinG tHe SliPPer
Turn the 5mm adjustment nut clockwise (to the right) to reduce
the slip or counterclockwise (to the left) to increase the slip.
cHanGinG tHe Pinion Gear/Gear ratio
Your vehicle comes with the 20T pinion gear. To change to an-
other pinion gear (sold separately), follow the directions below.
1
Unscrew the 3 screws holding the gear cover/motor mount
in place.
2
Remove the motor gear cover.
3
Remove the pinion gear.
4
Remove the screws holding the motor and move to the
appropriate holes (marked with the number of teeth on
the pinion) and reinstall the screws.
5
Place the new pinion gear on the motor shaft.
6
Reinstall the gear cover.
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 less 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 differ-
ent gearing options, pay close atten-
tion 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 with a
lower pinion gear and/or higher spur gear
is suggested.
To set the gear mesh, screw the motor into the corresponding
marked set of holes. For example, with a 20T pinion, the motor
screws must be screwed into the holes labeled “20”.
SettinG tHe Gear MeSH
The gear mesh has already been set at
the factory, and setting it is only neces-
sary 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 spur gear could be damaged by the
pinion gear of the motor. If the mesh is
too tight, speed could be limited and the
motor and ESC will overheat.
