GUIDE
Test for echo! Controlling a vehicle remotely is what defines RC as an
industry, and although we think our state-of-the-art radio gear is out of the
space age, the concept of a radio and receiver is over 100 years old. Modern
radios are essentially mini laptops that offer control of every parameter of
driving—including more bells and whistles than imaginable. Here are some of
RC’s most sought-after radios, which will impact the scene for 2013 and beyond.

UPGRADING YOUR RADIO
LiPo battery packs: Purchasing a LiPo battery
pack for the transmitter is the first upgrade to
make. Aside from being rechargeable, it has
numerous advantages over AAs like lighter
weight, a smaller footprint, higher capacity,
and higher cycle life. A LiPo transmitter pack
will pay for itself very quickly.
Making a pistol grip: Although the grips
on some transmitters are nice, adding
aftermarket grips, such as golf club,
tennis racket, and baseball bat grips, has
advantages. These grips are supple and very
comfortable. Also, if they become soiled over
time, they may be replaced easily, and they
also protect the plastic and rubber of the
pistol grip itself.
Customized steering wheels and grips:
To add some panache to the new radio,
manufacturers offer replacement steering
wheels. While it may seem like an aesthetic
improvement alone, drivers with larger
hands often appreciate a larger diameter
wheel for comfort and control.
Skins: Vinyl decal “skins” are becoming very
popular in RC, and they are an excellent way
to add some personality and protection to
your radio. Some manufacturers also offer
transparent screen protectors to prevent
the LCD screens from becoming scraped or
scratched.
KO PROPO EX-1 KIY Concept 2.4GHz FHSS Radio
System w/KR-411FH Micro Receiver
Taking modular units to the next level, KO’s Kustomize
It Yourself (KIY) platform is composed of three
different modular units—steering, throttle, and master.
The advantage is upgradability. As technologies
advance, KO will release new modules, so
upgrading to the newest state-of-the-art is only
a matter of purchasing portions of the radio,
instead of an entirely new unit. Of course, the
system has an insane amount of features, but the
CPU has been upgraded to a 12bit processor—20%
faster than KO’s previous offering.

Item no. KOP80095; $179.99 kopropo.com
RADIO SYSTEM CARE
Protect the receiver: A vehicle’s receiver is one of the most delicate
components on the entire vehicle, so it must be installed and treated
carefully. Always use all of the rubber plugs to cap-off any unused
channels—preventing water, dust and debris from entering the
internals. Use high-quality, RC-specific servo tape to adhere the
servo to the chassis. And in nitro applications, try wrapping the
receiver with a thin layer of foam before placing it in the receiver box.
Rebind occasionally: Although in theory 2.4GHz systems search
for the best signal over time, it doesn’t hurt to rebind the radio and
receiver occasionally, especially after traveling far distances or after
long periods of storage.
Use a strap: Most radios offer some form of loop or eyelet to attach
a strap or lanyard through. Although nobody wants to looks like a
total dork, wearing the lanyard or strap around your next can prevent
damage from accidentally dropping it during a long main or bashing
mishap.
Unplug the battery: Always unplug the transmitter battery pack—or
remove the AAs—when the transmitter is not in use. This will prevent
the batteries from slowly draining and will also decrease corrosion on
the terminal leads and inputs over time.
Get a radio case: Most radios have small, delicate switches, antennas,
triggers, and LCD display screens—all of which can be easily damaged
in storage or transport. After buying a new radio system, invest in a
sturdy, padded carrying case. This will make traveling easier and help to
protect the new investment.
Look for updates: As radio systems become increasingly more
software-based, it is important to check the manufacturer’s website
regularly for firmware updates. Downloading updates or fixes will help
the electronics to stay current and compatible with new items when
they eventually hit the market.

POPULAR RADIO FEATURES
2.4GHz: Often hidden by
proprietary names like FHSS
and DSS, 2.4GHz radio systems
synch on a variety of different
frequencies, as opposed to being
relegated to a specific frequency
like the radios of yesteryear.
2.4GHz systems automatically
search for the best available
frequencies and eliminate the
possibility of crossing frequencies
with other racers or drivers.
Channels: Each transmitter and
receiver function uses a specific
channel on which to operate.
Going beyond 2-channels opens
the possibilities to operating
auxiliary functions like a rock
crawling dig, multiple steering
servos, telemetry systems, and
much more.
Adjustable endpoints: Endpoint
adjustments or “EPAs” allow
users to fine tune the throw of the
throttle and steering inputs. These
fine adjustments are especially
valuable in nitro applications,
where adjusting the throttle/
brake linkages is vital.
Dual rate steering: Most
transmitters allow users to
adjust the overall throw of the
steering servo—known as dual
rate steering. Dialing back the
steering throw has advantages
and prevents users from
overcorrecting steering inputs. It
also may be used to prevent servo
strain and subsequent damage.
Digital displays: Many highend transmitters feature highresolution LCD displays, which
offer users the ability to monitor all
of the transmitter and telemetry
readings at a glance.
Rechargeable battery ports:
Some transmitters feature a
port to plug-in a rechargeable
battery pack. Losing transmitter
voltage can spell disaster, and
when forced with a long main or
bashing session, using a highcapacity rechargeable pack is a
must.
Lap timers: Using the radio’s lap
timer helps racers to track their
progress during practice rounds,
when the track’s transponder
system is not available.
Computer compatibility: Many
transmitters can interface with
a PC. This ability offers an array
of advantages. It allows users
to download new firmware
applications to stay current,
upload radio and race info for
long–term storage, and adjust
transmitter parameters via PC.
Model memory: Since it doesn’t
make sense to have a different
transmitter for each vehicle,
many transmitters feature
a memory storage function,
preventing users from needing
to reset and recalibrate the
transmitter settings each time
the vehicle is changed.
Exponential adjustments:
Exponential offers a throttle or
servo rate that is not directly
proportionate to the transmitter
input. Utilizing exponential allows
for finer adjustments during initial
inputs and increased function
toward the end of the inputs.
Throttle/steering trims: Being
able to adjust and calibrate the
throttle and steering trims is
critical. Since it’s difficult to
manually place servo horns at
perfectly neutral positions, and
ESCs don’t zero perfectly either,
being able to manually override
the electronics is important
during the initial setup.
Telemetry: Some radio systems
offer onboard telemetry,
which allows users to monitor
parameters like engine/motor
temperature, RPM, top speed,
battery voltage and battery
temperatures, directly on the
transmitter. Notifications can
usually be set to alert users if
something reaches a critical level.
