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 
turn. If you notice any decrease in 
performance after making changes 
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.

Adjusting the Toe-in

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
