TUNING ADJUSTMENTS

Once you become familiar with driving your Nitro Slash, you may wish
to make adjustments for better driving performance.
Adjusting the Slipper Clutch
The Nitro Slash features an adjustable slipper clutch on the spur gear to
help protect the drive train from sudden shock loads (such as landing
off of jumps with the engine at full throttle). Under normal conditions
the slipper clutch should not slip. Before adjusting the slipper clutch,
turn the model off. Do not adjust the slipper clutch while the engine is
running.

Use the supplied glow plug
(universal) wrench to tighten the
slipper nut (clockwise) until it stops,
and then back the nut out 1/4

to the slipper clutch adjustment,
then it may be too loose. The slipper
must not be allowed to slip during
normal acceleration or the slipper
could be damaged.

Geometry and alignment
specs play an important roll
in your truck's handling, so
take the time to set them
correctly. Set the steering
trim on your transmitter
to neutral. Now, adjust your 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. If you run
out of adjustment, then the steering servo will have to be re-centered
(see "centering the servos" on page 31). For increased stability add 1-2
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. Adjust the front and rear wheels to 1 to 2
degrees negative camber. These adjustments should be set with the
truck positioned at its normal ride height.

Fine Tuning the Shocks
The four shocks (oil dampers) on your Nitro Slash have tremendous
influence on its handling. Whenever you
rebuild your shocks, or make any changes
to the pistons, springs or oil, always do it
carefully and in sets (front or rear). Piston

head selection depends on the range of
oil viscosities that you have available. For
example, using a two-hole piston with
lightweight oil will give you the same
damping as a three-hole piston with heavier
oil. We recommend using 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 with
less resistance and provide less damping,
while thicker oils provide more damping. Use
only 100% pure silicone shock oil to prolong

seal life. From the factory, the Nitro Slash uses
50W oil.
The ride height for the Nitro Slash can be adjusted by adding or
removing the clip-on spring pre-load spacers. Note that changes in
ride height will occur when changes in shock angle or spring rates are
made. You can compensate for ride height changes by changing the
pre-load spacers on the shocks
