TUNING ADJUSTMENTS
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 are available at Traxxas.com.
