9. Completing the model vehicle
a) Setting the remote control and speed controller
You must adhere strictly to the manufacturer's instructions when setting the remote control and programming the
speed controller.
The steering must be set so that the model moves straight ahead when the steering control on the transmitter is in
themiddleposition.Thesteeringdeectiontotherightandleftmustbethesameandthesteeringandwheelsshould
not touch at the full steering angle.
The speed controller must be set so that the motor is switched off when the driving function control on the transmitter
is in the middle position. In addition, the driving functions such as forward drive, stop with brake function and reverse
drive must be reliably detected by the speed controller so that the motor is controlled accordingly.

b) Conguring the tyre track

In this case, two distinctions are made:
A toe-in means that the front wheels are facing slightly
inwards (see Figure 1A).
A toe-out means that the front wheels are facing slightly
outwards (see Figure 2B).
The model chosen for Figure 1 has freely visible wheels
which are not covered by a chassis for a better represen-
tation.

A toe-in contributes to a better lateral guidance of the tyre
and therefore to a more direct steering response. It also
effectively supports directional stability.
