Adjusting Gear Mesh
Incorrect gear mesh is the most common cause of stripped spur
gears. Gear mesh should be checked and adjusted anytime a gear
is replaced. Access the gears by removing the single screw on the
top gear cover.
To set the gear mesh,
cut a narrow strip of
notebook paper and
run it into the gear
mesh of the motor.
The motor is mounted
to an aluminum
motor mount. Loosen
the single motor mount screw with the
provided 2.5mm wrench to slide the motor
mount. Slide the motor and pinion gear into
the spur gear. Retighten the motor mount
screw and then remove the strip of paper.
You should be able to run a fresh strip of
paper through the gears without binding
them. Gear mesh can be checked visually by
removing the gear viewing port cover.
WHEELS AND TIRES
Your model uses 12mm axle hexes which allow many types of
aftermarket tires and wheels to be adapted for use on your model.
Most will affect the overall width and the suspension geometry of
the model. The offsets and dimensions designed into the model's
wheels are intentional; therefore, Traxxas cannot recommend
the use of other non-Traxxas wheels with different specifications.
Experimentation with different types of tires is recommended

to see which ones work the best on the terrain where the model

is run. Soft compound tires with many short spikes generally
work better on hard, dry surfaces. In loose dirt, a tire with large
spikes should perform better. Foam tires can be fitted for use on

pavement or indoor carpet tracks. See your parts list for accessory
wheels and tires.
When selecting tires, consider the overall diameter of the tire. If the
overall diameter is significantly larger than the stock tire's diameter,
you will need to use a smaller pinion gear to compensate for the
larger tire. If you wish to install tires with a diameter greater than 4
inches or 100mm, Traxxas suggests you configure the transmission
for 'underdrive' gearing. Details on making this simple modification
