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.
During the drive the tyres are pushed apart in the front because of the
rolling friction and this is why they are no longer precisely parallel to the
driving direction. To balance this, the tyres of the stationary vehicle can
be adjusted so that they point slightly inwards. This toe-in improves the
lateral cornering of the tyres and thus a more direct response to the
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 that 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
steering knuckle arm (1).
Because it has a left and right hand thread at either
end, it does not need to be dismantled to be adjusted.
Turn both steering knuckle arms evenly
(left and right front wheel). Otherwise, you
need to adjust the trim of the transmitter
(or even change the steering servo con-
trol by adjusting the servo rod (2).
The alignment of the rear wheels is permanently pre-
set and cannot be changed.
