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 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!
Setting front axle alignment:
For the front axle, alignment can be set by turning the track
rod lever (A). Because it has a left and right hand thread
each, it does not need to be dismantled to be adjusted.
Turn both track rod levers 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 axle stub (B) also has two attachment points for the
steering knuckle arm, which are used for changing the de-
flection angle of the front wheel (Ackermann angle).
The manufacturer already selected the best setting.
Therefore, you should not change the attachment point.
Setting rear axle alignment:
The vehicle has a stiff axle at the rear. The camber is not adjustable.
