Basic Driving Skill
OVAL COURSE 1
is the simplest course using two pylons. It looks simple at first
sight to drive a car along, but it will require some practice to
achieve quick and sharp turns. Practice both ways, clockwise and
counterclockwise, until you can make both rounds in the same period of
time. A figure “8” exercise can also be done in the same track.
finishing course No.1 and No.2, you have mastered the basic driving
techniques. Now you should proceed to complex courses.
Build a road course with the pylons, from basic figure “T” and “L”
courses to more complicated circuits, assortments of figure “L” and
hairpin curves, high-speed curve and slaloms.
OVAL COURSE 2
two or three pairs of pylons forming gates and run your car through
them as accurately as possible. You will find it much harder than
the oval course No.1. For the first period of time, arrange the
pylons with a wide space, narrow them gradually until the space is one
meter. Practice in both rotations, clockwise and counterclockwise.
CAR STEERS OPPOSITELY?
you are a novice driver and not sufficiently accustomed to R/C car
driving, you may feel as if the car steered oppositely to the
transmitter movement when the car runs towards you. To solve this
problem, try to imagine you were driving in the R/C car. As you
repeat the basic exercise, you will get used to this way of thinking
and control the model smoothly.
WHERE TO LOOK WHEN DRIVING
you drive a car, it is important what you keep your eye on.
Suppose the squares described are the field of vision. Put your
point of sight on the forward part of the area of vision with the car
placed at the back. If your point of sight is on the car itself,
you cannot keep clear of obstacles ahead because it would be too late
to notice them. Corners would also be difficult to see.
Practicing on a Circuit
an R/C car in an open area is one thing, but running it on a closed
circuit is entirely different. Even though you are not competing,
and only practicing, driving on a circuit will improve your driving
skill. You can also observe techniques used by experienced
drivers running highly tuned cars at the circuit.
1. CORNERING TECHNIQUES
particular skill is required for driving a car just straight, and the
drag speed is limited by the car’s own inherent performance
capability. However, at curves, your finesse of taking corners
affects the result even among cars of the same performance.
Especially in speed races, the cornering technique is one of the
decisive factors. After becoming accustomed to the car, try to
practice smooth, speedy and stable cornering.
and Fast-out” is a golden rule in controlling speed in curves, and
“Out-in-Out” instructs how to steer a car. Briefly, you should
control speed in “slow-in and Fast-Out” manner and steer a car in an
WHAT’S “SLOW-IN AND FAST-OUT”
when entering into a curve and picking up the speed after the apex of
the curve is the technique. In the case of entering bends without
reducing speed, the car is forced to slow down before finishing corners
to lose speed and stability. In the worst cases, the car might
spin or run off the course. It also gets the car moving too late
to pick up speed. As a result, “Slow-in and Fast-out” is the
fastest way to take corners.
is, as illustrated, a way of turning curves from the outside line of a
course into the inside line to which the car will come closest to the
apexes (clipping points) and finishing the corner back to the outside
line, thus making the longest possible turning radius. By
utilizing the full width of the course, the car will make an easier
turn than the actual curve. This will allow the car to run
through the turns faster.
*Set the clipping point after the Apex
some cases, it may be advantageous to set the clipping point a little
after the apex because it allows easier later half cornering and
enables the car to accelerate out better.
ACCELERATION DURING THE LATTER HALF OF A CURVE IS IMPORTANT
“Slow-in and Fast-out” and “Out-in-Out” techniques are established from
attaching more importance to velocity in the latter half of cornering
than the first half. This has to do with the acceleration of a
car. A car increasing speed in the latter half of a turn can take
the lead in the successive straight track, provided the cars should
have the same pickup and maximum speed capability. This principle
is true anywhere except in a very wide road where you are not required
to reduce the speed at all.
WHEN PERFORMANCE GETS BETTER, THE DRIVING LINE SHOULD BE ALTERED
your car’s top speed becomes faster, by using a higher performance
motor, etc., more deceleration will be required when entering
corners. Not only the speed, but the handling characteristics,
tire grip etc. will influence the driving line a car should take.
THE LAST CURVE IS THE MOST IMPORTANT IN A CHAIN
last curve is the most important in continuous curves. In
successive bends of a road, steer your car so that it will make the
easiest turn at the last curve. Then you will be able to
accelerate as soon as you reach the straight.
CONSIDER COMPLEX CURVES AS ONE
complex curves as one integrated compound curve. In the case of
complex curves with different radii, you can manage to get through by
considering them as one curve.
TAKING THE INSIDE LINE ON GENTLE CURVES
the “Slow-in, “Fast-out and the “Out-in-Out” rules are basic for
cornering, if the curve is gentle enough, there is little or no need to
reduce speed. Naturally, it is advantageous to use the inside
line throughout the curve, when possible.
OBSERVE THE ENTIRE CIRCUIT LAYOUT
several tips are offered when describing individual curves, a circuit
is a succession of straights and curves. It is therefore
important to observe the entire layout and select a smooth running line
for completing a lap. Repeat practice laps, trying various routes
to find the ideal line. Shortening your lap times during trials
is a very rewarding part of R/C cars.
2. ADVANCED CORNERING TECHNIQUES
just steering alone but combining with throttle control, various
cornering techniques can be obtained. Practice and master this
for much faster and smoother cornering.
FOUR WHEEL DRIFT
technique is achieved by oversteering while decelerating in the early
stage of cornering. As the rear wheels start to slide outward and
the nose heads towards the inside of the corner, neutralize the
steering and add power. The car will take the corner with all
wheels sliding. This technique is suitable for rear wheel drive
and 4WD racecars.
technique is unique to front wheel drive cars. Enter a curve
straight, then cut power and steer around the curve at the same
time. The car will change direction quickly, straighten out and
accelerate going through the corner.
term means to steer the wheels against the turn of a corner. If a
car enters the corner too fast, the rear wheels could start to skid,
resulting in a spin. To stop this, steer into the direction of
the skid. This technique is used to prevent the car from spinning
and is not for enhancing cornering speed.
WEIGHT LOAD SHIFT ACCORDING TO POWER APPLIED
running at a steady speed, the load is divided between the car’s front
and rear wheels in a fixed ratio. During deceleration, more of a
load is put on the front wheels because of inertia, resulting in
sharper steering response. Opposite of this is acceleration,
where more of a load is put on the rear wheels, producing a slower
steering response. Both the four-wheel drift and tack-in use this
weight load shift to obtain the desired cornering effect.
PRACTICE AS IF YOU WERE RACING
race is run with many cars at the same time. If you want to
become familiar with racing, the best way is to hold practice sessions
with your friends as a group. It is important to feel the
difference between driving a car by yourself and driving with
competition. You’ll notice that the track seems somewhat narrower
with all the cars and becomes difficult to steer your car on the line
you desire. Experience is what counts to get your car ahead of
result of a race sometimes depends upon the start. However, a
quick start is not always advantageous. Accidents are most likely
to occur between the start and the first corner because participating
cars are running close to one another. Decide how you should
start according to the characteristics of your car and the course
TAKE AND HOLD THE INSIDE LINE DURING CORNERING
competing with your rivals during cornering, take the inside line for
maintaining the lead. It is difficult for you to beat your
opponent in the corner by trying to pass him on the inside line because
both cars are running at about the same speed. If your car can
manage a higher maximum speed than the others can, only then, is
passing on the outside line possible. Trying to take the inside
line too early can lead to over-running the corner resulting loss of
time and opening a space for another car. While you’re at the
edge of the track, your rival can easily pass you on the inside.
In order to avoid this, stick to the inside, forcing him to delay his
acceleration. Taking and holding the inside line in the corner is
a golden rule for taking the lead at corners. Confrontation
between cars during cornering are the most exiting moments during a
race, but be sure to avoid the selfish type of driving that can cause a
collision and damage that will spoil the race for everyone.
HOW TO PASS OTHERS
are various places in which you can try to pass another car. A
straight is the safest place to do so. It is dangerous to start
passing a car when you are following too close behind it. When
you judge that it is possible to pass, steer your car a little as soon
as possible and attempt to pass. You may pass on either side,
wherever there is more room. If the space on each side is about
the same, it is advisable to go inside to make the next corner
on a corner is dangerous as compares with passing on a straight.
If the driver of the car you are trying to pass is not skilful in
control, your car is liable to be involved in a spin. To make
passing easier, it is advisable to go on the inside of the rival’s car
and pass it after turning the corner. It is very difficult to
pass it on the outside of the corner even if your car is much faster.
IF YOUR CAR LOSES STABILITY
your car has hit another car and control is lost, reduce the
throttle. If you try to restore control by steering, the car
might be further disturbed. Start accelerating again only after
the car has slowed down and is stable.
