ADJUSTING YOUR MODEL
Going Brushless
Brushless motors provide increased power output and greater
efficiency. Upgrading the high-stall gear clutch assembly and stock
pinion is required to provide the extra transmission and driveline
strength to make the Telluride capable of handling extreme
brushless power. Replace the high-stall gear clutch assembly with
the slipper clutch assembly (part #6878), and replace the stock
pinion with the 32-pitch, 13-T pinion (part #3943). If you plan
to run LiPo battery packs to power a LiPo-compatible brushless
system, optional battery hold downs (part #6727X) are available to
accommodate larger, high-capacity LiPo battery packs.
Wheels and Tires
Many types of aftermarket tires and wheels can 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. The diameter of the wheels is an innovative
design, and there is a variety of different tires available for you to
experiment with in addition to the included tires on the model
(listed in your parts list). Experimentation with different types of
tires is recommended to see which ones work the best on the
terrain where the model is run. When selecting tires, consider the
overall diameter and the rubber compound (hard or soft). If the
overall diameter of the tire is significantly increased, you will need
to use a smaller pinion gear to compensate for the larger tire. 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. See your parts list for accessory wheels and tires.
TUNING THE SEALED GEAR DIFFERENTIALS
The action of the model’s front and rear gear differentials can
be tuned for different driving conditions and performance
requirements without major disassembly or removal of the
suspension system.
From the factory, the differentials are sealed to maintain consistent
long-term performance. Changing the oil in the differential with
either lower or higher viscosity oil will vary the performance
characteristics of the differentials. Changing to higher viscosity oil
in the differential will reduce the tendency for motor power to be
transferred to the wheel with the least traction. You may notice this
when making sharp turns on slick surfaces. The unloaded wheels
on the inside of the turn have the least traction and tend to spin
up to extremely high RPMs. Higher viscosity (thicker) oil causes the
differential to act like a limited-slip differential, distributing more
equal power to the left and right wheels.
Telluride will generally benefit from higher viscosity oil when
climbing or racing on low traction surfaces.
Note
: Heavier oil will
allow power to be transferred even with one or more tires off the
ground. This can make the vehicle more likely to overturn on high-
traction surfaces.
From the factory, the front and rear differentials are filled with SAE
100,000W viscosity silicone oil.
Only use silicone oil in the differentials. Traxxas offers various
viscosity oil between SAE 10,000W, and 500,000W (see your parts
list). The differentials have to be removed from the vehicle and
disassembled to change/replace oil. Follow the steps below to
access and refill the front and rear differentials:
