Static Camber Adjustment
The wheels can be set to have either
positive or negative camber (see
illustration below). The camber angle
changes as the wheel moves up and
down through its range of travel. Static
camber is the camber angle at the wheel
when the vehicle is set at its normal,
stationary ride height.
The suspension pivot balls located in the axle carriers adjust the static
camber. Camber is factory-set at negative 1-degree, with the pivot balls
threaded all the way into the suspension arms. To adjust static camber,
insert the supplied 2mm hex wrench into the pivot ball (compressing
the suspension until the arms are parallel to the ground will allow for
easier hex wrench engagement). Negative camber can be increased by
unthreading the lower pivot ball. Zero camber or positive camber (not
recommended) can be achieved by unthreading the upper pivot ball.
Note that camber changes will also effect the toe angle of the wheel
being adjusted.
Static Camber Base Factory Settings
Front: 1-degree negative camber each side
Rear: 1-degree negative camber each side
TRANSMISSION TUNING
Adjusting the Slipper Clutch
Slash VXL 4WD and E-Revo VXL
are equipped with an adjustable
Torque Control slipper clutch which
is built into the large spur gear.
The purpose of the slipper clutch
is to prevent over-stressing of the
drivetrain and transmission gears. It may also be used to regulate the
amount of power sent to the rear wheels to prevent tire spin. When it
slips, the slipper clutch makes a high-pitch, whining noise.
To adjust the slipper clutch, remove the receiver box cover.
The slipper clutch is integrated into the main spur gear on the
transmission. The slipper clutch is adjusted using the spring-loaded
locknut on the slipper shaft. Use the supplied universal wrench.
To tighten or loosen the slipper nut, insert the 1.5mm hex wrench
into the hole in the end of the slipper shaft. This locks the shaft for
adjustments. Turn the adjustment nut clockwise to tighten (less
slippage) and counter-clockwise to loosen (more slippage)
Tuning The Sealed Gear Differentials
The Slash VXL 4WD and E-Revo VXL’s front and rear gear differentials
allow the left and right wheels to spin at different speeds while turning
so that the tires do not scuff or skid. This decreases the turning radius
and increases steering performance.
The performance of the differentials can be tuned for different driving
conditions and performance requirements. The differentials are filled
with silicone differential fluid, and are sealed to maintain consistent
long-term performance. Changing the oil in the differential with either
lower or higher viscosity oil will vary the performance characteristics
of the differentials. Changing to a higher viscosity oil in the differential
will reduce the tendency for power to be transferred to the wheel with
the least traction. You may notice this when making sharp turns on slick
surfaces. The unloaded wheels on the inside of the turn have the least
traction and tend to spin up to extremely high rpms. Higher viscosity
(thicker) oil causes the differential to act like a limited-slip differential,
distributing more equal power to the left and right wheels. Your model

Zero camber
A camber gauge (available
at your local hobby shop)
can be a useful tool for
alignment setting.
To achieve a good starting
point for the slipper clutch,
tighten the slipper clutch
adjusting nut clockwise until
the slipper clutch adjusting
spring fully collapses (do not
over tighten), and then turn
the slipper clutch nut counter-
clockwise ¾ to 1 turn.
