minutes before the next start to avoid damage. Fire hazard!
Chassis Tuning Guide
On your Sand Rail chassis two parameters can be adjusted: the toe of the front axle and the camber of both
axles.

Maintenance
To have fun with your model over a long period, occasional service work is required to get your model in good
condition and to minimize wear.
• Remove dirt or dust depending with compressed air or a soft brush after each use. For stubborn dirt, a
harder brush or a toothbrush can be used.
• To clean the body/fuselage no chemical cleaners such as thinners may used, as this damage the plastic
of the body/fuselage. Normally a piece of soft cloth is ok, stubborn dirt can be removed with washing-up
liquid.
• Check the tightness of all screws and tighten if necessary.

Toe-in:
zero toe
the setting is done via the steering linkage. More toe-in gi-
toe-out toe-in
ves a better directional stability, but also poorer turn in at
corner entry, and generally a less direct steering.
More toe-out effects a direct response to steering com-
mands and more aggressivity at corner entry, but is also
more difficult to control.
A neutral setting reduces tire wear and gives a neutral
handling.

Camber:
The tires should always have road contact with
all the running tread. This is achieved with neutral
or negative camber (about 2-3 °) on both axes -
more negative camber decreases the grip level
again. Ideally, the camber is adjusted so that the
tires wear is evenly.
Positive camber drastically reduces the grip and
should, if at all, only be used on the front axle, to
make the cornering less aggressive.
