Power supplies: At least to begin with, you may wish to
limit the track power supply to one original equipment power
pack per lane, powering each lane separately. Powering each
lane separately prevents the cars from fighting each other for
available amperage and ensures that each car gets consistent
power. This makes the cars easier to drive in competition
because they don’t get a sudden increase in power when a car
stops or deslots. All three of our recommended racing classes
will perform well enough on a single stock power pack per lane.
Using stock power packs also provides a degree of uniformity
from one track to the next if several different persons’ track
layouts are included in your race schedule, particularly if the
layouts all use the same track system. It is true that there
can be a noticeable difference in power output between one
standard power pack and another. However, over a race schedule
in which each racer runs an equal amount of time on each lane of
each track the difference is effectively canceled out, along
with any differences in length or cornering speed between the
lanes themselves.
A disadvantage to using stock power packs is that their power
output is not adjustable. This means you can’t reduce the
voltage when small children or total beginners are running.
However, there’s a simple way to overcome this shortcoming.
Plug all of your power packs into an outlet strip with a master
on-off switch and an adjustment dial built into it. You will
then be able to turn down all four power packs as one, and the
on-off switch lets you start and stop the power to all lanes
together.
Taken together, restrictions on controllers and power supplies
remove most if not all advantages to be gained by using illegal,
ultra-high performance motors and magnets which cause the car to
draw more amperage than the power pack can provide and require
controllers with different specifications. They also control
costs by ruling out solid-state electronic controllers that can
easily cost more than $100 each. In the process many of the
rules on car preparation and specifications become at least
partially self-enforcing.
As with the
racing classes, at some point you may move on to different rules
on tracks, power, and controllers. Meanwhile, what we have
described here will give you an excellent place to start with
organized racing, providing lots of inexpensive and enjoyable
racing along with the experience necessary to make effective
choices for the future of your race program.
