b) Setting the Alignment
Wheel alignment (toe-in = figure “a”, toe-out = figure “b”) describes the
relation of the wheel level to the driving direction.
The tyres are pushed apart in the front by rolling friction when driving.
Therefore, they are no longer precisely parallel to the driving direction.
To compensate, the tyres of the stationary vehicle can be adjusted so
that they point slightly inwards. This toe-in improves lateral cornering of
the tyres and leads to a more direct response to steering.
If a milder response to steering is desired, this can be achieved accord-
ingly by adjusting a toe-out, i.e. the wheels of the stationary vehicle
point outward. An alignment angle of 0° on the front axle ensures the
best driveability on almost any ground.
An alignment angle of more than 3° toe-in (a) or toe-out (b) will lead to handling problems and decreased
speed. It will also increase tyre wear.
The figure above shows a strongly over-emphasised setting. It is only used for showing the difference
between toe-in and toe-out. If such a setting is used for the vehicle, it will be very difficult to control!
Set alignment for the front wheels:
For the front axle, alignment can be set by turning the
adjustment screw (A).
Because the setting screw has a left and right hand
thread at either end, the steering lever does not need
to be dismantled to be adjusted.
Turn both setting screws evenly (left and right front wheel). Otherwise, you need to adjust the trim of the
transmitter (or even change the steering servo control by adjusting the servo rod).
The alignment of the rear wheels is permanently pre-set and cannot be changed.
