9. Vehicle Settings
a) 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
accordingly 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!
For the front axle, alignment can be set by twisting the steering knuckle arm (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 leg has several attachment points (B)
for the steering knuckle arm, which are used for
changing the turning angle of the front wheel (Ak-
kermann angle).
The manufacturer already selected the best
setting. Therefore, you should not change it.
The alignment of the rear axle wheels is firmly pre-set and cannot be changed (this would have very little effect on
driving behaviour of the vehicle).
