Basic Tuning Adjustments - Traxxas Slash 4x4 Ultimate 6807L Owner's Manual

All of the toe links are
installed on the truck so the
left-hand thread indicators
point to the same direction.
This makes it easier to
remember which way to
turn the wrench to increase
or decrease toe link length
(the direction is same at all
four corners). Note that the
groove in the hex indicates
the side of the toe link with
the left-hand threads.

BASIC TUNING ADJUSTMENTS

Once you become familiar with driving your model, you might need
to make adjustments for better driving performance.
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
gear cover.
To set the gear mesh, loosen the
motor screw. Cut a narrow strip
of notebook paper and run it into
the gear mesh. Slide the motor
and pinion gear into the spur gear.
Retighten the motor screws and then
remove the strip of paper. You should
be able to run a fresh strip of paper
through the gears without binding them.
ADJUSTING THE CAMBER
The camber angle of both the front and rear wheels can be adjusted
with the camber links (upper turnbuckles). Use a square or right-
angle triangle to set the camber accurately. Adjust the front wheels
to 1° to 2° of negative camber. In the rear, adjust the wheels to 1° to
2° of negative camber. These adjustments should be set with the
truck positioned at its normal ride height.

ADJUSTING THE TOE-IN
Toe-in refers to the angle of the wheels as viewed from above.
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° toe-in). This will ensure the same amount of
steering in both directions.
Front Toe-In: For increased stability add 1° to 2° of toe in to each
front wheel. Use the turnbuckles to adjust the alignment.

Rear Toe-In: You will notice that the Slash 4X4
Ultimate's rear wheels point inward slightly,
which aids in stability. This is called toe-in, and is
measured in degrees. If the wheels point straight
ahead, parallel with the chassis' centerline, then the
wheels have "zero toe-in." The Slash 4x4 Ultimate is
equipped with aluminum rear stub axle carriers that
1°-2° provide 4° of rear toe-in. You will note that the axle
carriers are labeled "L" and "R," to indicate left and
right. The axle carriers may be installed on the opposite sides (L on
