Mini 4WD Basic Knowledge
You can enhance the performance of
your Mini 4WD by using many of Tamiya's upgrade parts,
which can provide increased power or faster
speeds. In order to do this,
you will need to understand the
basic elements of Mini 4WD vehicles.
1. Motor
The installation of a tune-up
motor is the best way to increase the speed of your car.
There are seven kinds of motors available as
upgrades.
All of them achieve higher
performance than the standard motor included in the kit.
It is essential to select the right motor
since some are designed for top speed, while others are geared more for
cornering.
2. Gear Ratio
At a given motor's output, top
speed and acceleration are determined by the gear ratio.
In comparison, between a 4:1 gear ratio and
a 5:1 gear ratio, the smaller 4:1 ratio is more suitable for speed oriented
circuits,
while the bigger 5:1 produces more
acceleration.
Performance Differences Among The Various Gear Ratios
Different gear ratios are
available for all chassis.
Use a small ratio for high speed
courses and a bigger one for technical courses with many curves and downs.
Set up the gears according to the
track you are racing on.
3. Tires
Tires play an important part when
it comes to your car's performance.
Take into consideration tire
weight, diameter, and width,
to determine what type of tire
will work best for the course you will be running.
Difference in
Diameters
Small Diameter: Good for a quick start, but not for top speed.
Small diameter tires lower the center of
gravity and help your car corner better.
Large Diameter: Good top speed and suitable for long straights. Better shock absorption for bumpy course joints.
Difference in width
Wide Tires: Provide stability during cornering. Good for
technical courses with banking curves and ups and downs.
Narrow Tires: Good for long straights. Less drag on the motor, which may give the advantage of longer run times.
Difference in Material
Rubber:: Weighs more than the sponge type, but grips better.
Useful for jumps and lower center of gravity.
Sponge: Weighs less than rubber type, but has a lower grip characteristic. Reston: Lighter than the regular sponge type and has better gripping. Can be used on all kinds of wheels.
Tire Maintenance
4. Wheels
Wheels, as well as tires, play an important role in tuning
up your car. There are various types with different diameters and structures.
Select the right
one for your application. Most types can be used on any Mini 4WD; however,
if you have a Fully
Cowled Mini 4WD, body modification will be required if you use anything other
than the standard,
small-diameter type wheels.
Type
of Wheels
Small Diameter Type: Narrow Wheels (which are standard for the Fully
Cowled Mini 4WD),
Wide Super Low-Height Wheels and
Wheels for semi-pneumatic tires.
Large Diameter Types: Included in a Super Mini 4WD snap kit. A lot of designs are available. Pick one that appeals to you. One Way Type: Light One Way Wheels, Wide One Way Wheels, Low Height One Way Wheels, Narrow One Way Wheel.
Normal Wheel vs. One
Way Wheel
5. Rollers
Rollers are a must when racing on
walled circuits. Altering the rollers will enable you to set up your car for
the demands of any track.
Key points in using rollers are their size,
location and angle.
Make sure you have clearance between the
rollers and the body tires.
Any contact will slow your car
down or even damage parts. Most races have regulations concerning the number
and size of rollers.
Also the position and size of the rollers
can affect your overall length and width of your Mini 4WD.
the local regulations to make
certain that your car is in compliance before you race.
