Adjusting the Toe-in
Geometry and alignment specs
play an important roll in your
model's handling. Take the time
to set them correctly. Set the
steering trim on your transmitter
to neutral. Now, adjust your
servo and tie rods so that both wheels are pointing straight ahead and
are parallel to each other (0-degrees toe-in). This will ensure the same
amount of steering in both directions. For increased stability add one- to
two-degrees of toe in to each front wheel. Use the turnbuckles to adjust
the alignment.

Adjusting the Camber
The camber angle of both the front
and rear wheels can be adjusted
with the camber rods (upper
turnbuckles). Use a square or right-
angle triangle to set the camber
accurately. The stock camber

of the front wheels is -1 degree
of camber. In the rear, the stock
camber is -1.5 degrees. These
adjustments should be set with the
truck positioned at its normal ride
height with a battery installed.
Fine Tuning the Shocks
0
°
The four shocks on the model greatly influence its
handling. Whenever you rebuild your shocks, or
make any changes to the pistons, springs or oil,
always make changes to them in pairs (front or
rear). Piston selection depends on the range of oil
viscosities that you have available. For example,
using a two-hole piston with a lightweight oil will,
at one point, give you the same damping as a three-
hole piston with heavier oil. We recommend using
the two-hole pistons with a range of oil viscosities
from 10W to 50W (available from your hobby shop).
The thinner viscosity oils (30W or less) flow more
smoothly and are more consistent, while thicker oils
provide more damping. Use only 100% pure silicone
shock oil to prolong seal life. The model's ride height
can be adjusted by adding or removing the clip-on,
spring pre-load spacers. Adjust the ride height so that the suspension
arms are slightly above being parallel to the ground. Observe how the

spin outs. Experiment with different springs and shock oils to find what
works best for your current track conditions.

Big bumps and rough terrain require a softer

suspension travel and ride height. Racing
on a prepared track or on-road use requires
a lower ride height and firmer, more
progressive suspension settings. The more
progressive suspension settings help reduce
