Without a doubt, the number-one question asked in
RC is: how can I get more speed and power out of my
vehicle? No matter what kind of car or truck you’re
wheeling, there are six essential ways to get more oomph and mph out of your
machine. Some require a more significant donation to your favorite hobby store
than others, but without question, these tips will help your ride put down more
power and post a bigger number on the GPS readout. Without further delay, and in
no particular order, here are six ways modify your machine for higher horsepower
and maximum mph.

You may be able to get a
significant speed boost by
simply changing your car’s
pinion and/or spur gear.
Installing a larger pinion or
smaller spur gear will alter your
car’s gear ratio, which a;ects
how far (and, thus, how fast) it
travels with each revolution of the
motor. Pinion and spur gears are
pretty inexpensive—usually only
$5 to $10 apiece. When making
gearing changes, do so gradually. Don’t
jump more than two teeth on the pinion or five teeth
on the spur gear at a time. If you “overgear” your car
by installing a gear ratio that your motor does not have
the power to turn, you’ll strain and potentially overheat
the motor, and your car will actually go slower. It’s like
the gears on a bicycle: If you shift to the highest gear
and try to pedal away from a standstill, it’s very hard on
your legs. ;ink of your car’s motor as your legs. If you
gear for absolute peak speed, use that gearing for speed
runs on hard surfaces only. If you use it for general stop-start, multi-terrain driving, you’ll overheat the motor.
A larger pinion/smaller spur gear will make your
car slower to accelerate but will increase its top
speed—to a point. Don’t overdo it.
