Tuning
For advanced drivers, there are further setup measures available for shock absorption.
Thus, in addition to the measures described above, you have the possibility of changing the absorption by ex-
changing the shock-absorber springs with more resistant/less resistant springs with progressive coiling. You can
also use a shock-absorber oil with lower/greater viscosity or piston plates with a different size/number of holes.
Adjusting the wheel tracking
Steering
The track arms located on the steering knuckles
are fastened on one track rod (a) each by me-
ans of ball heads. These track rods are in turn
connected to the steering plate (b) by means
of ball heads. When the steering plate is moved
to the right and left, the wheels also turn to
the right and left. On the steering plate a lever
(c) engages, which is connected elastically on
an axis between the chassis and top deck via
a spring to a second lever (d) positioned at a
right angle to it. The second lever is deflected
by the servo arm (f) via the steering linkage (e).
The elastic connection between the two levers
protects the servo from impacts against the
wheels during travel (servo saver) as a result of
the action of force on the wheels being absor-
bed and not being directly conducted into the
servo via the steering linkage.
Wheel tracking
Wheel tracking refers to the alignment of the wheels with regard to the longitudinal axis of the vehicle (direction
of travel).
If the wheels of one axle are not parallel to the longitudinal axis when at a standstill, but rather point inward at
the front, this is called toe-in.
Correspondingly, toe-out refers to wheels pointing outward at the front.
When travelling straight ahead, rolling resistance presses the wheels away from one another.
For compensation, the wheels can be adjusted with toe-in when standing still.
This positioning of the wheels can be brought about by changing the length of the track rods.
This changing of length (wheel tracking adjustment) is done using tensioning screws in the right and left track
rods.
Toe-in
Turning the tensioning screw counter-clockwise (to the rear) lengthens the track rod, and the rear of the
wheels is pressed outward. Toe-in during travel brings about better directional control of the tyre and more
direct response to steering. Driving with toe-in makes the inner sides of the tyres wear faster.
Toe-out
Turning the tensioning screw clockwise (to the front) shortens the track rod, and the rear of the wheels is
pressed inward. Adjusting with toe-out brings about a softer response to steering. Driving with toe-out makes
the outer sides of the tyres wear faster.
Adjusting the camber
The wheels are attached between the upper and lower wishbones. Changing the length of the top wishbone
brings about a change in the incline of the plane of the wheel. The wheel camber is the incline of the plane of
the wheel with regard to the vertical plane. When the top edges of the wheels on one axle are inclined inwards
(toward the middle of the vehicle), this is called negative camber. When the top edges of the wheels on one axle
are inclined outward (V-shaped), this is called positive camber.
