Once you become familiar with driving your S-Maxx, you might
need to make adjustments for better driving performance.
Adjusting the Slipper Clutch
The S-Maxx 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 of a 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
Your S-Maxx comes from the factory with zero degrees of toe-in
in the front, and one degree of toe-in in the rear.You can adjust
the toe-in on the front and rear of the truck. Set the steering trim
on your transmitter to neutral. Now, adjust your steering
turnbuckles so that
both front 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.
Adjust the rear toe
control links so
that the rear
wheels have 1˚ of
toe-in.
Adjusting the Camber
Two pivot balls are accessible through
the spokes of each of the wheels on
your S-Maxx. From the factory, the
pivot balls are completely tightened
into the suspension arms, which give
each of the wheels –1˚ of camber.
Unscrewing the bottom camber pivot
ball with a 2.5mm hex wrench will
increase the wheel’s negative camber.
You should not adjust the top pivot ball; unscrewing it will
increase positive camber and will also change the wheel’s toe-in.
Adjusting the suspension
The S-Maxx has adjustable suspension so that it may be
optimized for different kinds of terrain and driving styles.
Fine Tuning the Shocks
The eight shocks (oil dampers) on your S-Maxx 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 40W (available from your hobby
shop). The thinner viscosity oils (30W or less) flow with less
resistance and provide less damping, while thicker oils provide

Factory toe-in settings
can be achieved by
installing the rod ends
on the turnbuckles until
they bottom out against
the shoulder. If you desire
more toe-out, the tips of
the rod ends must be
trimmed to allow them to
screw down further onto
the turnbuckle threads.
