All of the toe links are
installed on the model 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, or if excessive gear noise is heard. To adjust gear mesh,
follow these steps:
1. Remove the right rear wheel using the supplied 17mm wheel wrench.
2. Loosen the two 3x15 motor-mount cap screws.
3. Using your 1.5mm hex driver, turn the mesh-adjustment set screw
counterclockwise to tighten the gear mesh. If needed, apply
gentle pressure to the motor to help the pinion slide closer to the
spur gear for a 'tighter'
gear mesh. Turn the
Strip of
set-screw clockwise to
Paper
move the pinion away
from the spur gear
to 'loosen' the gear
mesh. When properly
set, there should be
just a 'tick' of free play
between the pinion
and spur gears.
4. Tighten the two 3x15 motor-mount cap screws to hold the adjustment.
Tip: a strip of notebook paper can be inserted between the pinion
and spur gears to help set gear mesh. Before tightening the motor-
mount screws, insert the paper strip between the pinion and spur
gear. Adjust the pinion so it is completely meshed with the spur
gear, then tighten the motor mount screws. When the paper is
removed, you should have the required 'tick' of free play.
Adjusting the Toe-in
Geometry and alignment specs play an important roll in your
model's handling. Take the time to set them correctly. Turn off TSM
(see page 17); then, 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.
For increased stability, add 1°- 2° of toe-in to each front wheel. Use
the turnbuckles to adjust the alignment.

Adjusting the Camber

Screws
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°- 2° of negative camber. In the rear, adjust the wheels
to 1°- 2° of negative camber. These adjustments should be set with
the model positioned at its normal ride height.

Springs
The front and rear springs on the model have identical spring
rates. The springs' pre-load can be adjusted by turning the spring
pre-load adjuster. Adjusting the pre-load changes the ride height.
Adjust the pre-load so that the ride height at the front of the model
is 15mm, and the ride height at the rear of the model is 18mm.
