PEAk DETECTION CHARGER
Peak detection chargers monitor the battery during charging and
automatically shut off upon full charge. You can either purchase a peak
detection charger that plugs into a household AC wall socket or one
that requires you to also purchase a 12V power supply.
If using a charger other than a peak detection charger, make sure
your battery is fully discharged prior to charging. Many of these have
a 15–20 minute timer that allows you to set a charge time. If the
battery is not fully discharged, you can potentially over-charge your
battery pack. Do not charge any battery unattended, and monitor
for heat build up. If the battery pack is more than warm to the touch,
immediately discontinue charging. Read all safety precautions
supplied by the charger and battery manufacturer.

and secure it with the previously removed clip.
LOSI LSR-3000 RADIO SYSTEM
The XXX-SCB comes with the Losi LSR-3000 Radio System with
Spektrum™2.4GHz DSM®Technology. The system will neither interfere
with radio systems operating on legacy frequencies such as 27MHz
or 75MHz, nor will you experience any overlapping interference from
other 2.4GHz systems. The transmitter and receiver are bound together
from the factory to uniquely operate together.
Operation and Adjustment
Power Switch – Turns the transmitter On and Off.•
Dual Rate – (ST.D/R) Adjusts how much the wheels can turn left/•
right in equal proportion.
Steering Trim – (ST.TRIM) Adjusts the “Hands Off” direction of the•
XXX-SCB.

brake center.
Receiver
There is no adjustment required of the receiver. Please note the
different slots for connection.
AUXILIARY CHANNEL
THROTTLE CHANNEL
STEERING CHANNEL
BIND PORT
The bind slot is used to bind the transmitter to the receiver. The bind
process teaches the transmitter the unique GUID ID of the receiver.
Although the transmitter and receiver come bound, below are the steps
to rebind your transmitter and receiver should the need arise.
Rebind Process
1. Ensure the transmitter and vehicle are both turned off.
2. Using the supplied Bind plug (which looks like a standard servo plug
with a short wire loop installed), insert the Bind plug into
the receiver slot labeled BIND.
Note: You do not need to remove any other plugs to rebind.
3. Connect a fully charged battery to the EC3 connector on the ESC.
4. With the Bind plug installed, turn on the vehicle. Notice the
receiver LED is now blinking.
5. Turn on the transmitter. You will see a similar blinking LED
under a translucent cover on the back of the transmitter.
6. Both the receiver and transmitter LEDs will stop blinking and
be on solid, indicating they are bound.

7. Turn off the vehicle and then the transmitter.
8. Remove the bind plug from the receiver.
9. Turn on the transmitter and then the vehicle to ensure
operation. If the transmitter does not control the vehicle, repeat steps
1–8 above. If after several attempts you are unsuccessful, please
contact Horizon product support.
Receiver Antenna
Using your fingers gently straighten the antenna wire to be close to
vertical from the chassis for the best radio reception.
Factory Settings of Radio/ESC
The Electronic Speed Control was calibrated together with the radio
system at the factory. When you turn on and run the XXX-SCB for
the first time, you may need to slightly adjust the Throttle Trim. If the
vehicle creeps in reverse or in forward, make a fine adjustment to
the Throttle Trim knob on the transmitter. Sometimes the bumps and
bounces of transportation can slightly alter the settings.
PRECAUTIONS FOR DRIvING THE XXX-SCB
The Electronics in this vehicle are not waterproof. Avoid running•
the vehicle in or through standing water, wet grass, mud or snow.
This vehicle is quick:•
Do not run the vehicle if it will be out of sight for any amount-
of time.
Do not drive your vehicle near a crowd of people.-
Perform a check of the vehicle before going out to run it.-
Ensure the tires are not coming off the rims.-
Generally check the vehicle for items such as a loose wheel-
nut, or anything loose on the steering assembly. The vibrations
of running off-road tend to loosen screws and nuts.
The gearing of the XXX-SCB IS NOT meant for running the vehicle•
in tall grass.
Be careful driving when the battery is nearly discharged or the car•
is running slowly. You could lose enough power for the receiver to
shutdown and you may lose control.
When driving the XXX-SCB be cautious and use common sense.•
If your vehicle gets caught or stuck, do not pull the throttle in•
either forward or reverse. This will overload the ESC and/or motor
resulting in damage to one or possibly both.
After running a battery pack, allow the electronics several minutes•
to cool, before running the next battery pack.
Run Time
The single largest factor in run time is the mAh capacity of your battery
pack. The larger the mAh rating the more run time you will experience.
For example: if you have a 4600mAh battery pack, you can expect
close to twice the run time of a 2000mAh battery pack.
The condition of a battery pack is also an important factor in both run
time and speed. The longer you run, the hotter the battery plugs can
get. Check the standard plugs periodically. As batteries see more use
they will degrade in performance and capacity.
How you drive your XXX-SCB also affects your run times. If you are
performing runs, going from a standstill to full speed repeatedly, you
are taxing your batteries and electronics. Hard acceleration draws a lot
of current from any battery and will lead to shortened run time.
If the bearings are dirty, they will cause significant drag causing
reduced run times and speed.
To improve run times consider the following:
Keep your vehicle clean and maintained.•
Allow more airflow to the heat sink of the MSC 12L ESC.•
Change the gearing to a lower ratio; this will make the•
electronics run cooler. To change gear ratio, use a smaller pinion
gear, or a larger spur gear than those originally supplied. (The XXX-
SCB comes with a 16- tooth pinion and an 88-tooth spur gear.)
Change to battery packs of higher mAh rating.•
Verify you are using the best charger for your batteries. (See your•
local hobby dealer.)
TUNING, ADjUSTING
& MAINTAINING THE XXX-SCB
Periodically examine your XXX-SCB for the following:
Keep your vehicle clean using a brush to remove dirt and dust.•
Look for cracks in the suspension arms and other molded parts.•
Check that the tires are still glued to the wheels.•
Check that all the wheel bearings are clean and lubricated.•
Using your tools, attempt to tighten all the screws and nuts.•
Verify that the Camber Links and Steering Linkage are not bent.•
Check that the Toe and Camber settings are as desired and equal.•
Remove the gear cover.•
Check the Spur gear for wear.-
Check the Pinion gear.-
Check the Slipper Pads for wear.-
Take the shocks off the vehicle and check, especially•
if they appear to be leaking as it is time to rebuild them.
Look over all the wiring and connections for bare wire•
or any place which could lead to a short-circuit.
Verify the ESC is securely mounted to the chassis.•
Verify the receiver is still securely mounted to the chassis.•
Turn on the radio. If the Green LED is off or dim, replace the•
4 AA batteries in the transmitter.
After you become familiar with driving your XXX-SCB, you may need
to reset or make adjustments to the alignment. Make sure to work
on a flat work space.
This will enable you to easily and more quickly make both Toe-in
and Camber adjustments. These adjustments should be set with
the vehicle sitting at its normal ride height.

TROUBLESHOOTING GUIDE

9
BEC (Battery Elimination Circuit) The BEC eliminates the need for a receiver pack to power the radio system. On most electric vehicles
this is located in the electronic speed control (ESC), but can also be a stand-alone device.
BIND Process Programming a receiver to recognize the GUID code of only one specific transmitter or
transmitter module.
Calibration Also called ESC setup. It is the process used to match the transmitter throttle, brake and neutral to the
ESC.
Current Refers to the power flow from the battery to the ESC and Motor when used in the RC vehicle
environment. Typically this is measured in Ampere or Amp.
Deadband
This refers to the amount of travel (movement) on the transmitter trigger before the vehicle is
requesting the ESC to move the vehicle forward or backwards. It is an advanced adjustment used by
experienced drivers.
DSM
(Digital Spectrum Modulation)
The 2.4GHz technology of Spektrum radios.
ESC (Electronic Speed Control)
The ESC is what translates the signals passed from the transmitter trigger through the receiver into
commands that reach the motor to signal forward or reverse, acceleration or braking. The Xcelorin sys-
tem is an advanced electronic speed controller that is very efficient in passing precise requests to the
brushless motor. The BEC is also controlled by the ESC along with the Low Voltage Protection circuit.
GUID
Globally Unique Identification Code. Each individual module or radio is factory programmed with its own
unique serial code. In the binding process, the receiver is programmed to only recognize the GUID code
of one specific radio or module.
LiPo
A Lithium Polymer battery’s abbreviation indicating the chemistry used in these rechargeable
batteries. These batteries require special attention by the user and are only recommended for
the most experienced of users.
mAh The Milliampere Hour abbreviation, which represents the capacity of a battery pack. The higher this
rating the longer the run time of each charge.
Neutral Position
Referring to the Transmitter when at rest, meaning the throttle trigger and steering have no input. When
you turn the transmitter on, set it to the side while turning the car on, the transmitter will
be in a Neutral state.
NiMH The abbreviation for nickel-metal hydride rechargeable batteries. These have replaced the use of NiCd
batteries as the battery of choice in RC vehicles.
Profiles
The MSC 12RB has two (2) preset profiles. Forward Only and Forward and Reverse profile. The Forward
only profile can be selected for racing purposes. The Forward/Reverse profile is great for running in
your neighborhood.
Receiver A device mounted into the vehicle that receives and decodes a signal sent by a transmitter. Servos, ESC
and other devices are plugged into the receiver.
Resistance
As used here refers to the power loss from the battery to the ESC and Motor. Typically this is
measured in Ampere or Amp. Too much resistance between the battery, ESC and motor can result in
low performance and run time.
Servo An electronic device connected to the receiver used to actuate steering control of the vehicle.
Spektrum
The technology brand of 2.4GHz radio system supplied with the XXX-SCB. The use of this technol-
ogy eliminates the concern of conflicting frequencies found with older legacy radio systems. It further
reduces to a minimum potential radio interference common with the legacy radio systems of the past.
Transmitter Is the device held in your hand that relays steering and throttle/brake requests made to the receiver.
Trim
This is a setting used on the transmitter to make fine adjustments to the steering or throttle/brake
trigger. For steering you would use the trim to make the adjustment for the vehicle to drive straight
without adding steering input to the transmitter.
Thermal Shutdown
Refers to the ESC operating temperature. The MSC 12RB ESC monitors its internal temperature and
will automatically prevent the ESC from delivering power to the motor, preventing damage due to
overheating the ESC’s electronics.

this warranty without notice and disclaims all other warranties,
express or implied.
(a) This warranty is limited to the original Purchaser (“Purchaser”) and

that Horizon will, at its option, (i) repair or (ii) replace, any Product
determined by Horizon to be defective. In the event of a defect, these
are the Purchaser’s exclusive remedies. Horizon reserves the right to
inspect any and all equipment involved in a warranty claim. Repair or
