Introduction
Thank you for purchasing the JR Racing XS3 Synthesized
FM 3-Channel Radio system. You have likely choosen the
XS3 radio system for its synthesized PLL channel select
capabilities found on both the transmitter and the receiver,
eliminating the need for crystals and providing you with
access to virtually all available channels on 27MHz or
75MHz.
For your convenience, blank data sheets have been included
in the back of this manual. Once you have input all the
necessary data for a particular model into your transmitter,
we strongly recommend that you immediately write that
information down on the data sheet provided. This will
insure that in the rare case of a memory failure, you will
not lose the models’ setup data.
This system has been designed to provide RC racers with a
high quality, user-friendly radio system that can be relied
upon year after year, race after race. The XS3’s grip dial
accessible auxiliary third channel is ideal for use as a mixture channel in gas boats or as a transmission shifter for
vehicles such as the Traxxas T-Maxx. It is important that
you carefully read this manual before attempting to operate
your XS3 system.

RC Safety Precautions
1. Radio control models are not toys. They are capable
of inflicting serious injury to people and property. Use
caution at all times when operating your model.
2. You are responsible for the safe operation of your RC
model. You must properly install, test and operate your
model with a clear sense of that responsibility. Do not
take risks that might endanger yourself or others.
3. Running an RC car in the streets is very dangerous to
both drivers and models. Avoid running your model in
areas occupied by full-size automobiles. To locate areas
where you can safely operate your model, contact your
local hobby shop for RC tracks or clubs in your area.
4. When running an RC boat, keep it away from any swim
mers, full-size boats and wildlife. Also, watch carefully
for fishing lines that may get tangled in the propeller.
6. If at any time while operating your RC model you sense
abnormal model functioning, end your operation immediately. Do not operate your model again until you
are certain the problem has been corrected.
Caution: Control of your model is impossible
without sufficient voltage for the transmitter and
receiver. A weak transmitter battery will decrease
your range of operation, and a weak receiver battery
will slow servo movement and decrease your range
of operation. Check your receiver pack voltage often
to avoid losing control of your model. When using
a model that operates both the electric motor and
the receiver from the same battery (Battery
Eliminating Circuitry or BEC), you should discontinue use when the top speed sharply decreases or
you’ll quickly lose control of your model. For safe
and reliable performance of your RC model, please
carefully read and follow the guidelines below.
5. Before operating your model, make sure your frequency
is clear. If someone else is operating on the same
frequency, both models will go out of control, possibly
causing damage to the models, as well as others.
Steering Tension Adjustment
Steering tension is adjustable via the recessed screw
located beneath the steering wheel (see page 7 for exact
location). Turning the screw clockwise increases the
steering tension.
Charging Jack
Located on the left-hand side of the transmitter is the
charging jack that accepts only JR wall chargers. Please
do not attempt to use any other brand of wall charger, as
it may be reverse polarity and can cause damage to your
system. Only use the JR wall charger when the XS3 is
equipped with Ni-Cd batteries (JRPB958, available
separately).

Receiver/ Servo Connections and Installation
Your RS300 receiver is equipped with Battery Eliminator
Circuitry (BEC). The receiver gets its power from the
model’s Ni-Cd battery pack, thus saving the weight of an
additional receiver battery. Ni-Cd batteries from 4.8–8.4V
(4–7 cells) can be used safely. Higher voltage packs may
damage the receiver and servos.
Note: When using a separate receiver Ni-Cd as a
power source, the operating voltage range is
4.8–6.0V (4- to 5-cell).
Attention: Make sure the male and female connectors
have the correct polarity (+/-) before connecting. The servo
lead and receiver case are molded so that the lead can only
be inserted correctly. Be sure to orient the servo plug correctly for proper insertion.
You may use a separate receiver battery to power the
receiver (such as for some electric boats or in gas-powered
vehicles). A Ni-Cd pack plugged into the battery socket on
your receiver will operate your receiver. You can also use
alkaline batteries with the included battery box.
If you use a mechanical speed controller, please make sure
it has the correct connector for a BEC system (red connector). See Figure A below for a typical setup. Most electronic
speed controllers are set up for BEC operation and plug
directly into your receiver (Figure B). See Figure B for a
typical setup and check your speed controller‘s manual for
correct installation.

Receiver/ Servo Connections and Installation
Your RS300 needs to be mounted so the receiver is isolated
and floats to avoid damage from shock or vibration.
Placement of the RS300’s case should not come in direct
contact with hard or rigid surfaces.
1. Mount the RS300 receiver with double-sided tape. (Use
extra layers of double-sided tape, particularly if it is thin,
until you build up a cushioning pillow layer.)
Do not use glue to mount the receiver!
2. Run the antenna wire up through a plastic antenna tube
and let the excess wire hang out the top of the tube.
3. Do not cut, coil, or bundle excess antenna wire—range
will be reduced!
Operating Your Model
It’s important to learn the proper sequence for switching
on/off your radio system.
Before Operation
Switch on the transmitter, then the receiver.
10
After Operation
Switch off the receiver, then the transmitter. This ensures
that you will always have a signal to the receiver and that
your RC model will not operate out of control when you
turn off the transmitter.

Lithium Battery
Your XS3 radio system is equipped with a five-year lithium
battery backup system. This system is designed to protect
and retain all radio programming in the event that the
transmitter batteries drop below the required 9.0 volts, or
the transmitter battery case is removed during battery
changes. If after five years it becomes necessary to replace
the lithium battery, return your system to the Horizon
Service Center (see address, page 37) for repair.

display screen by pressing the Channel key.
Pressing the Channel key again will scroll back
through the channel select and model name
screens. (For more information on this feature,
please see page 26.)
Memory Backup
If the Memory Backup screen appears, this indicates the
possibility of a ROM problem or the lithium battery is dead.
If you switch the power off and on again, but the transmitter
is in the default mode with all data lost, it is strongly suggested that the XS3 transmitter be returned to the Horizon
Service Center for servicing (see Warranty Information,
page 37).

Synthesized Channel Select
The XS3 has memory for six models. This feature allows
for six different models to be operated with the same transmitter (additional receivers and servos must be purchased
separately) or one model with six different race setups.
One of the XS3 transmitter’s most valued features is its
ability to synthesize the frequency needed for operation on
a single select channel without the need for replacing a
crystal. Depending on the operating frequency band of your

Throttle Deadband
The throttle deadband feature is used to reduce/eliminate
the dead throttle area that exists at neutral to the starting
point of throttle and from neutral to the starting point of
braking. This area is sometime known as deadband. As
more throttle trim (also known as static brake) is applied,
more of the dead trigger area right off neutral exists. To
eliminate the throttle deadband, adjust a forward value such
that your vehicle’s wheels just start to turn when the trigger
is slightly squeezed. This provides the most accurate feel
and eliminates the dead area in the throttle. To eliminate the
braking deadband, adjust the brake value such that your
vehicle starts to slow down when the trigger is slightly
pushed. This provides the most accurate brake feel and
eliminates the dead area when braking.

End-Point Adjustment
The End-Point Adjustment feature of the XS3 allows the
maximum travel of both the steering, throttle and Auxiliary
Channel 3 (optional) servos to be increased or decreased
in each direction to achieve the exact servo movement
needed. The End-Point Adjustment range is from 0% to
125% and is factory set to 100% for both channels. The
value displayed on the screen depends on the current
position of the steering wheel, trigger, or trim lever to be
adjusted. This feature is very useful either to maximize
servo travel or to reduce servo over-travel to eliminate
servo binding (servo moves further than control mechanism allows), without the need for mechanical linkage
adjustment.
The screens below are accessed by turning the wheel
to the desired direction to be adjusted (left or right), by

For example, Throttle-to-Auxiliary channel mixing can be
used for independent front and rear wheel brakes. Each
time the throttle/brakes is moved, the auxiliary channel will
move in the direction and to the value input being given by
the throttle channel. Mixing is proportional, so small inputs
to the throttle will result in small output from the auxiliary
channel. The adjustment range is from -125% to 0% to
125%. If the rate is negative, the channel is mixed in the
opposite direction.
Both mixes share a single mixing “offset.” The purpose of
the mixing offset is to redefine the neutral position of the
auxiliary channel, which can be set using Grip Lever A
when “LN” is selected in the Auxiliary Channel 3 function.
If the “LN” selection is turned off in the Auxiliary Channel 3
function with a offset value currently present, the value will
continue to act as a mixing offset until the value is either
cleared or changed. If a mix is not required, it is strongly
suggested the mixing rate be set for 0%, which is the
default.

of individual lap times based on a 999 second up-timer.
Up to 50 laps and times from 3.0 to 99.9 seconds can be

The Lap-Timer is started by pressing Grip Button C. Once
active, as shown by the blinking word “LAP,” pressing Grip
Button C again will begin recording the time of the next lap.
Note: A 3.0 second lap is the quickest lap allowed.
This prevents accidental double pushing of Grip
Button C when recording lap times. If more than
50 laps are recorded, each new lap will overwrite
the oldest lap held in memory.)
To stop the Lap-Timer, press the Increase and Decrease
keys at the same time. To restart the Lap-Timer, press Grip
Button C. To reset the Up-Timer, press the Channel key to
show the Up-Timer display screen. With the Up-Timer
stopped, press the Increase and Decrease keys at the same

Accessing the Sub-Trim Function
Sub-Trim
The Sub-Trim function of the XS3 is an electronic trimming
feature that allows the neutral position of the servo on
either the steering, throttle or auxiliary channel (optional) to
be moved, while allowing the electronic trim lever for that
channel to remain in the center position. This feature is
very useful as it allows the servo arm/wheel position to be
moved to help with control linkage installation, eliminating
the need to make mechanical linkage adjustments.

Although the Sub-Trim function is a very useful feature, it is
suggested that only small amounts of sub-trim be used so
that no unwanted, non-equal servo travel is created. It is
suggested that less than 30 points of Sub-Trim be used
during adjustment. If more than 30 points of Sub-Trim are
required, it is suggested that a mechanical linkage
adjustment be performed.

Steering Trim
The XS3 electronic Steering Trim lever, located above
the steering wheel, allows the center position of the servo
to move in either direction. Steering travel end-point
adjustment values remain completely independent from the
steering trim, unless the trim value exceeds the selected
end-point values. (For example, if trim values are set at 30
and end-point values at 15, steering trim will over-ride/
alter the end-point value.) Each click will provide 0.3° of
trim to the center of the steering servo with a maximum of
12° allowed.
Note: Each click will not always result in a change
of the value displayed.
To adjust the steering trim servo position, move the electronic Steering Trim lever left or right. As soon as the trim
is moved, the “STC” Steering Trim screen will be displayed
unless the trim lever is untouched for two seconds. To reset
the trim value to 0, press the Increase and Decrease keys at
the same time while the “STC” screen is displayed.

Grip Lever B: Steering Dual-Rate Trim Adjustment
The Steering Dual-Rate adjustment, located at Grip Lever B,
allows the Dual-Rate value (maximum servo travel) to be
increased or decreased within a range from 100% through
20% of the total end point value established in the steering
EPA function. This function is very useful in race conditions
as it allows you to custom tailor the steering radius and
sensitivity for the current track conditions.
