c) 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!
Setting front axle alignment:
For the front axle, alignment can be set by turning
the adjustment screw (A). Because the adjustment
screw has a left and right hand thread at either end,
it does not need to be dismantled to be adjusted.
Turn both adjustment screws of the left and right front
wheels evenly. Otherwise, you need to adjust the trim
of the transmitter or even correct the steering servo
control (e.g. adjust servo rod or attach servo arm to
the servo differently).
The attachment points of the track rod in the axle stub (B) and the steering plate (C) should not be changed,
since they influence the Ackermann angle (the wheel on the inside of the curve deflects more than the outer
one. The manufacturer has already made the best setting here.
