In this case it recommends to leave the rear wheels within the entire range of the suspension perpendicularly to the
ground. A small enlargement of spreading (negative fall) at the front suspension will improve the steering control of the
car when squeezing the suspension together. But: In the case of a too large change of the camber the bearing surface
of the tire is strongly made smaller.
WAYS TO IMPROVE YOUR DRIVING
The improvement of your driving skills is extraordinarily important, often however unconsidered aspect with R/C driving.
Consistent „smooth" driving is the key to understand the effect of even smallest setup changes of your car on its hand-
ling. Here a few hints, which will help to driver faster from run to run.
1.
Avoid collisions
The winner of a race is often not the fastest vehicle, but that, which is involved fewest into accidents and which ma-
kes the fewest driving errors. Drive carefully in places, in which vehicles become wedged into one another again and
again.
Stay away from vehicles, which are slower or are controlled by inexperienced drivers. If you drive near too closely at
their rear end, such drivers can run scared, make an accident and entangle you therein. You lose less time, if you wait
for the fact that a slow vehicle is passed through a critical curve, as if you are entangled into an accident and have to
wait that the (hopefully attentive) track marshal helps your car. Apart from the fact that such an accident costs time, it
can cause also a damage of your vehicle, whereby you are ruled out possibly completely from running. Remember that
a collision with a wall with a maximum speed of 60 – 80 km/h corresponds to a case of a fall from your car of the roof of
a house. If the manufacturer wanted to make an R/C car absolutely indestructible, he would become much too heavy,
that the car would be still competitive. The better solution is called "drive carefully!"
2.
Driving through a curve correctly
You drive through a curve correctly, if you start from the outside, then to the inside at the apex of the curve and then go
again to the outside.
If more closely traffi c on the course prevails, you will not always be able to drive the racing line in the curves. In these
cases decrease the speed and try to drive as closely as possible along the inside of the curve. Colliding vehicles be-
cause of close traffi c are normally pushed of the curve. Also track conditions can force you to change your racing line in
the curves. It is often better to drive around holes and peaks, instead of driving over it, only to follow the racing line.
With the entering into a curve reduce the speed, on the exit accelerate your vehicle. Reduce the throttle with the entran-
ce gradually. Thereby you shift the weight of the car on the front wheels and improve the steering performance of the
car (see also chapter „damping"). Do not accelerate too strongly, because otherwise your R/C car slides to the outside
of the track, or drives, under-steering, to the external wall. Smooth, consistent throttle manipulation and steering is the
key to fast driving through curves. „Burnouts" and full braking increase the wear of the car, increase the danger of an
accident and result in a lower average speed. It is important that the R/C car always rolls! If you try to drive completely
smooth and consistent your lap-times will improve naturally.
