PrecautionS
»
Never touch moving parts.
»
Never disassemble while the batteries are installed.
»
Always let parts cool before touching.
adjuStinG the SliPPer
Turn the 4mm 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 24T pinion gear installed for the
included 2S battery. If you want to use a 3S battery, install the
included 20T pinion gear.
1
Unscrew the gear cover screws and remove the gear cover.
2
Loosen the motor screws and slide the motor back.
3
Loosen the setscrew and remove the installed pinion gear.
4
Place the new pinion on the end of the motor shaft so the
setscrew is located over the flat on the shaft.
5
Position it so the teeth line up with the spur gear
and secure the pinion by tightening the setscrew.
6
Reinstall the gear cover.
GearinG
Your vehicle has been equipped with
the optimal gearing for the stock plat-
form. 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 over-
heating 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 tempera-
ture range of the components. The mo-
tor 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.
1
Unscrew the gear cover screws and remove the gear cover.
2
Loosen the motor screws and slide the motor back.
3
Put a small piece of paper between the pinion and spur gears.
4
Push the gears together while tightening the motor screws.
5
Remove the paper. The gears should move a small amount.
6
Reinstall the gear cover.
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 dam-
aged by the pinion gear of the motor.
If the mesh is too tight, speed could
be limited and the motor and ESC
will overheat.
