With the exception of large-scale models
with gasoline engines, model cars use “nitro
engines,” which are named for the fuel they
burn. Model engines run on “nitro,” a mix of
nitromethane, methanol, and oil that you
purchase at the hobby store.
;e exhaust pipe ... to
keep things simple.
It’s called a “tuned” pipe
because it is specially
shaped, or tuned, to
enhance engine power.
Yep, holds the fuel.
As its name states,
the receiver receives
the signals from the
transmitter. ;e signals
are relayed to the steering
servo and speed control
to operate the model. In
this Traxxas Slash 4X4,

Servos are the “muscles” of
radio control. A servo has a
motor inside of it that drives a
set of reduction gears to amplify
its torque. ;e torque is needed
to push and pull the steering
system to direct the car.
LIPO & NIMH Two mo : NiMH is nicke ive, but hea s importa n NiMH batteries. ONLY charge LiPo batteries with a LiPo-specific charger, or you will ruin the battery, potentially with a battery fire. Regardless of battery type, never leave batteries unattended while charging.
;e vast majority of RC models are
sold RTR, but if you dream of building
a car yourself from a kit, you still have
options. High-end racing cars are still
o;ered almost exclusively as kits, but
these aren’t the best first-car choices
unless you plan to jump straight into
competition. Tamiya is the king of kits,
with everything from super-simple
beginner cars to competition models to
ultra-detailed scale vehicles including
tractor-trailers. All are easier to build
than you think, and if you already
imagine building a car is fun to do, you
won’t be disappointed doing it yourself.
On the other hand, if spinning wrenches
isn’t your thing … stick with an RTR.
;at’s why they make ’em!
