There is Bind, channel one, channel two and auxiliary slots.
The bind slot is used to bind the transmitter to the receiver. The Losi LSR-3000 DSM® radio system uses a unique GUID ID to “bind” the
transmitter to each receiver. This bind process has been performed during assembly and is described should you replace the receiver
or during a trouble shooting exercise you be requested to rebind your transmitter and receiver.
Although the transmitter and receiver are set “bound” at the factory, below are the steps required to rebind your transmitter and
receiver should the need arise.
Rebind Process
1.
2.
Ensure that the transmitter and vehicle are both turned off.
Using the supplied Bind plug (which looks like a standard receiver plug with a short wire loop installed), insert the Bind plug
into the receiver slot labeled BIND. When you look down on the receiver slots it is the slot furthest from the LED, and nearest
to the corner of the receiver.
Note: You do not need to remove any other plugs to rebind.

With the bind plug installed, turn on the vehicle. Notice the LED is now blinking.
You are now ready to turn on the transmitter. You should notice on the back of the transmitter a similar blinking LED
under a translucent cover.
Both the receiver and transmitter LEDs will stop blinking and be on solid, indicating that they have bound
themselves together.
Turn off the vehicle and then the transmitter.
Remove the bind plug from the receiver.
Turn on the transmitter and then the vehicle to ensure operation. If the transmitter does not control the vehicle,
please repeat steps 1-7 above. If after several attempts you are unsuccessful please call Horizon product support.
The bind process is complete. Your vehicle’s radio system is now ready for use.
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 Desert Truck
for the first time you may be required to slightly adjust the Throttle Trim. If the vehicle creeps in reverse or in forward just make a fine
adjust to the Throttle Trim knob on the transmitter. Sometimes during the bumps and bounces of transportation the settings can be
slightly altered.

Driving the Desert Truck
Please note the following precautions before running
your Desert Truck.
•
The Electronics in this vehicle are not waterproof and you
must avoid running the vehicle in or through standing
water, wet grass, mud or snow.
•
This vehicle is quick:
o Do not run the vehicle if it will be out of sight for any
amount of time.
o Do not drive your vehicle near a crowd of people.
•
Perform a check of the vehicle before going out to run it.
o Ensure the tires are not coming off the rims.
oGenerally 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 Desert Truck’s gearing choice from the factory 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 Desert Truck 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
and is not covered by your warranty.
•
After running a battery pack, allow the electronics several
minutes to cool, before running the next battery pack.
How you drive your Desert Truck will also affect your run
times. If you are performing runs, going from a standstill to full
speed repeatedly, you are asking a lot from 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 12RB ESC.
•
Change the gearing to a lower ratio, this will make the
electronics run cooler. This can be accomplished by using
a smaller pinion gear, or a larger spur gear than those
originally supplied. (The Desert Truck comes with a 16tooth pinion and an 88-tooth spur gear.)
•
Change to battery packs of higher mAh rating.
•
Is the charger you’re using the best at charging your
batteries? Check with your local hobby dealer.
Run time consideration for the Desert Truck vehicle.
The single largest factor in run time is the capacity mAh of
your battery pack. The larger the mAh rating the more run time
you will experience. On the same note, the longer you run, the
hotter the battery plugs can get. Please check the standard
plugs periodically.
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. As batteries see more use they will
degrade in performance and capacity.

Tuning, Adjusting & Maintaining the Desert Truck
Tuning the Front End of the Desert Truck
Shock Location: The Desert Truck has two mounting locations
on the front shock tower. The position can be easily adjusted
by simply moving the top of the shock to another hole. The
standard location (outside hole on the tower) works best on
most surfaces. Moving the top of the shock inward a hole will
slow steering response and make the Desert Truck smoother
in bumps. The standard position on the arm is in the middle,
which offers the best balance. Running the inside shock
location will give the Desert Truck more steering into the turn
and less steering on corner exit. Running the shock location
outside on the front arm will give you less overall steering
into the turn and keep the front end flatter through the turn,
making the Desert Truck smoother and easier to drive. This can
be used on high traction surfaces.
Periodically examine your Desert Truck 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.
o Check the Spur gear for wear.
o Check the Pinion gear.
o 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 that the ESC is securely mounted to the chassis.
•
Verify the receiver is still securely mounted to the chassis.
•
Turn on the radio and if the Green LED is off or dim replace
the 4 AA batteries in the transmitter.
After you become familiar with driving your Desert Truck,
you may need to reset or make adjustments for better
driving performance.
All of the Camber and Steering Linkages have been assembled
in the following way.
Using the supplied flat metal turn buckle wrench if you need
to SHORTEN any link on the Desert Truck rotate the wrench
towards the front of the vehicle (counter-clockwise). If you need
to LENGTHEN any link then rotate the wrench towards the rear
of the vehicle (clockwise).
Static Camber: This refers to the angle of the wheels/tires
relative to the surface (viewed from either the front or back).
Negative camber means that the top of the tire leans in toward
the chassis. Positive camber means the top of the tire leans out,
away from the chassis. Camber can be precisely measured with
after-market camber gauges, sold at a local hobby shop. It can
be measured (roughly) using any square (to the ground) object
by checking the gap between the square edge and the top of
the tire. Testing has shown that 1 degree of negative camber
is best for most track conditions. Increasing negative camber
(in the range of 1-2 degrees) will generally increase steering.
Decreasing negative camber (in the range of 0-1 degree) will
generally decrease steering and the Desert Truck will feel easier
to drive as a result. This is, most often, a very critical adjustment
in tuning your Desert Truck that can be made quickly and easily.
Just as in a real car, alignment is an important factor in your
vehicle’s handling. When you are ready to make adjustments
it is a good idea to have a flat work space to place your vehicle
on. This will enable you to easily and more quickly make both
Toe-in and Chamber adjustments. These adjustments should be
set with the vehicle sitting at its normal ride height.
16
TM
Inboard Camber Location: The Desert Truck has three
different inner locations with vertical adjustment for the front
camber tie rod. In general, the lower or further out the inside
position is, relative to the outside, the more camber gain (total
camber change through the total throw of the suspension) is
present. This is an adjustment that is difficult to make a generic
statement for as it can have slightly different results on various
conditions. The following is a summary of how this adjustment
will usually impact the handling of the Desert Truck. A longer
front camber link will usually make the Desert Truck feel stiffer.
This will help keep the Desert Truck flatter with less roll, but can
make the Desert Truck handle worse in bumpy conditions, it
also will make the Desert Truck easier to drive. A shorter front
camber link will result in more front end roll, which will provide
more steering on tighter turns with the loss of some stability.
You will also lose some high speed steering but might gain
some more steering response. Too short of a front link may
make the Desert Truck feel “twitchy” or “wandery” meaning that
it may be difficult to drive straight at high speed.
Outboard Camber Location: In addition to the inboard
camber location, the Desert Truck also provides three outboard
mounting options. The middle location is the most used as it
provides the best and most consistent handling on different
surfaces. The outer location also helps the Desert Truck stay
tighter in turns with a more precise steering feel. Moving the
link to the inner hole will make the steering react slightly slower
and steer smoother. The advantage to the inner hole is that it
can increase on-power steering and help the Desert Truck get
through bumps better.
Toe-In/Out: This is the parallel relationship of the front tires to
one another. Toe-in/out adjustments are made by changing
the overall length of the steering tie rods. Toe-in (the front
of the tires point inward, to a point in front of the front axle)
will make the Desert Truck react a little slower, but have more
steering from the middle of the turn, out. The opposite is true
with toe-out (the front of the tires point outward, coming to a
point behind the front axle), the Desert Truck will turn into the
corner better but with a decrease in steering from the middle of
the turn, out. Toe-in will help the Desert Truck to track better on
long, straight, high-speed runs, where toe-out has a tendency
to make the Desert Truck wander. We recommend to run
between 0-degree of toe-in/out to 1 degree of toe-in.
Inboard Camber Vertical Adjustment: Washers are often
used under the inner ball stud mounting location; this is one
of the most important adjustments on the Desert Truck. You
should get a feel for how the number of washers affects the
handling. Adding washers will make the Desert Truck more
stable and keep the front end flatter. This works well on higher
traction surfaces. Removing washers will make the steering
more aggressive, which works well on lower traction surfaces.
This can be good in some conditions, but can also make the
Desert Truck difficult to drive in others. The best all-around
adjustment is with three washers as the vehicle comes built.
The washers that are used are included in an assortment
package of washers (LOSA6350).
Bump-In/Out: Bump-out (front of the front tires toe-outward
under suspension compression) will result in more off-power
steering and less consistent handling if you have too much
bump-out. This effect is obtained by adding washers under
the steering spindle ball stud. Bump-in (front of the front tires
toe-inward under suspension compression) will result in less
off-power steering and running. Too much bump-in can make
the steering feel very inconsistent. This effect is obtained by
installing a ball stud washer on the bottom of the spindle.
Testing has shown that running a little bit of bump-in (kit
setup) in the Desert Truck offers the best overall setup.
Caster: This is the angle of the kingpin from vertical when
viewed from the side of the Desert Truck. The Desert Truck
comes equipped with 30-degree spindle carriers and a 30degree kick-up angle. Total caster is determined by adding
the amount of kick-up (Desert Truck has 30 degrees) and the
kingpin angle of the front spindle carriers. Increasing total
caster will provide more steering entering a turn but less on
exit. Decreasing total caster will cause the steering to react
faster and increase on-power steering.
17
TM
but provide more on-power steering on high traction surfaces.
Pro-squat will also help the Desert Truck from pulling wheelies
on high bite surfaces. Also available is an aftermarket part that
is a 0 degree rear pivot block (LOSA2112), if pro-squat is desired
it is best to start with this option.
Tuning the Rear End of the Desert Truck
Shock Location: Moving the shocks out on the arm will result
in less forward traction and let the Desert Truck make more of
an arc through the exit of the turn. In general, when changing
shock locations on the arm, it will be necessary to go down one
spring rate when moving out on the arm.
Tuning the Chassis of the Desert Truck
Static Camber: Having the same definition as for the front end
and measured in the same fashion, rear camber can also be a
critical tuning feature. Testing has shown that running a small
amount of negative camber (.5-1 degree) is best. Increasing
negative rear camber (in the range of 1.5-3 degrees) will
increase stability and traction in corners, but decrease high
speed stability. Decreasing rear camber (in the range of 0-1.5
degrees) will decrease stability and traction in corners, but will
increase high speed stability.
Slipper Adjustment: After fully tightening the adjustment
nut (so the coils of the spring just touch) loosen the slipper
adjustment nut 2 1/4 turns. This will be a good starting point for
your slipper settings.
Inboard Camber Location: The Desert Truck has multiple rear
camber locations. Using a longer camber link will improve
stability and traction (grip). Using a shorter camber link will
increase steering while decreasing rear grip. Running the
camber link in the inside position on the shock tower will give
your Desert Truck more steering entering the turn as it will
let the Desert Truck set over the rear tire and give you more
forward traction exiting the turn. As you move the camber link
towards the outside of the Desert Truck, you will gain less initial
steering, however, you will gain more steering as the Desert
Truck exits the turn. The Desert Truck now has the capabilities
of a lower row of holes in the rear shock tower for the inner
camber link location. The lower hole gives the Desert Truck
more camber gain (more angle relative to arm = more camber
gain). This can be helpful when tracks get bumpy and rutted
to help the rear end of the Desert Truck go through the bumps
easier due to the increased camber gain of the tires.
Ride Height: This is the height of the chassis in relation to the
surface. It is an adjustment that affects the way your Desert
Truck jumps, turns and goes through bumps. To check the ride
height, drop one end (front or rear) of the Desert Truck from
about a 5-6 inch height onto a flat surface. Once the Desert
Truck settles into a position, check the height of that end of
the Desert Truck in relationship to the surface. To raise the ride
height, lower the shock collar on the shock evenly on the end
(front or rear) of the Desert Truck that you are working on. To
lower the ride height, raise the shock collar. Both left and right
nuts should be adjusted evenly.
Outboard Camber Location: Running the camber link in the
inside position on the hub will generate more rotation entering
a turn, but decrease steering on exit. Running the camber link
in the furthest outer position on the hub will generate more
stability entering a turn and increase steering on exit.
Every driver likes a little different feel so you should try small
ride height adjustments to obtain the feel you like. This should
be one of the last adjustments after everything else has been
dialed in (tuned). Do not use ride height adjustment as a
substitute for a change in spring rate. If your Desert Truck needs
a softer or firmer spring, change the spring. Do not think that
simply moving the shock collars will change the stiffness of the
spring; it will not.
Toe-In: Having the same definition as for the front end, the
toe-in can be adjusted on the Desert Truck with the rear hubs.
The stock toe-in is 3 degrees of inboard per side and 0 degrees
in the hub. Increasing rear toe-in will increase forward traction
and initial steering, but reduce straightaway speed. Decreasing
rear toe-in will decrease forward traction and “free-up” the
Desert Truck. Less toe-in can be used to gain top speed.
Anti/Pro-Squat: Increasing anti-squat is generated by raising
the front of the pivot block, relative to the rear of the pivot.
This will increase initial steering and forward traction. You can
increase anti-squat in 1 degree increments by using two .030
washers between the front of the pivot plate and pivot block.
Pro-squat is generated by raising the rear of the pivot relative to
the front. This will decrease forward traction and initial steering,

Adjusting Gear Mesh
Battery Position: This is a critical adjustment that is often
overlooked but can be very useful. Start by running the battery
spaced in the middle (standard setup with 6-cell battery pack).
Moving the battery back can improve rear traction on slippery
surfaces and steering response. Moving the battery back too
far can cause the rear end to swing through turns on some
tracks and “dump” the rear end causing instability issues. This
is a result of having the weight too far back. The Desert Truck
comes equipped with two foam battery spacers to split the
difference when adjusting the battery position, hence offering
a middle position when either extreme is inadequate.
Incorrect gear mesh is the most common cause of stripped spur
gears. To set the gear mesh, one method is to cut a narrow strip
of notebook paper and thread it in between the gears. Loosen
the motor screws and slide the motor and pinion gear into the
spur gear. Retighten the motor screws and then remove the
strip of paper. Or you can loosen the motor and carefully slide
the motor leaving a small amount of backlash (play) between
the spur and pinion gears. It should not be tight and if you look
up-close there should be slight movement of the spur before
contacting the teeth on the pinion gear.
Camber Rise Relationship: The Desert Truck setup out of the
box comes with less front camber gain than the rear camber
gain. The reason for this is that less front camber lets the front
end drive flatter and makes the Desert Truck more stable. By
having more camber gain in the rear, the Desert Truck has more
rear traction, this helps the rear tires accelerate through the
bumps and ruts.
Gear Ratio
Changing the gearing provides you a quick and easy way
to tune the Desert Truck. Use the temperatures of both the
motor and your battery pack as a guide to gearing to your
environment. When the Motor is above 160-170 degrees
Fahrenheit or the batteries are above 125-135 degrees
Fahrenheit, these are both strong indications that you should
drop the pinion size smaller. This would be a lower gear ratio
or larger number, for example from 11.25 to 12.40. Going up
a pinion size is called gearing higher or a small number, for
example 11.25 to 10.6, and will increase power consumption
and allow more speed.
Wheels and Tires
The tires come pre-mounted with the vehicle and should be
checked to make certain they stay glued to the wheels. The
wheel spinning speeds can pull the rubber tire away from the
rim. When a tire or tires come loose from the rim you will notice
the vehicle is hard to control.
Use the following formula to calculate the overall ratio for
combinations not listed on the gear chart:
Tip the vehicle on its side and using both hands to hold one
wheel at a time, use your thumb to press the tire away from
the rim. If you see a tire pull away for the rim use Losi Tire Glue
(LOSA7880 thick or LOSA7881 thin) to re-glue. It only takes a
small drop of glue generally. Be careful this is CA-type glue and
you do not want to glue your fingers to the wheel and tire.
Spur Gear Size
Pinion Gear Size
X 2.43 = Final Drive Ratio
When using higher gear ratios, it is extremely important to
monitor the temperatures of the battery and motor. If the
battery is extremely hot, and/or the motor is so hot that you
cannot touch it, most likely you are over-geared and drawing a
lot of current.
Use safety goggles when gluing tires.
Check the mounting of the tire periodically to ensure proper
performance and handling.
Steering Assembly: Occasionally, check the steering assembly
and you may notice increased looseness. There are several
components which will wear out from use: tie rod ends
(part LOSA6074), the servo saver (part LOSA1610), the bell
crank bushings (part LOSA1620), and the Drag link ball ends
(LOSA6074). You can easily replace these components to restore
factory specifications.
The gear combination that comes on the Desert Truck (16tooth pinion / 88-tooth Spur) provides high-speed running
intended for asphalt and off road dirt surfaces. This gearing is
not recommended for running in grass or constant starting and
stopping.
Storage
Note: The bell crank bushings may be replaced with
ball bearings (part LOSA6912).
When you are through running the model for the day
•
Blow it off with compressed air or use a soft bristled paint
brush to dust-off the vehicle.
•
Always disconnect and remove the battery from the
model whenever the model is stored. If the model will
be stored for a long time, then also remove the batteries
from the transmitter.

Vehicle runs slowly/slow acceleration:
Troubleshooting your Desert Truck
Check the battery connectors.
Confirm that battery is charged.
Many questions are the result of simple user errors or minor
adjustments which are easily addressed. If after reading below
you cannot resolve your problem, then please call Horizon
Customer Service at 1-877-504-0233.
Vehicle will not reverse:
Make sure the throttle trim is at neutral.
Radio system does not work properly:
Recalibrate/Setup the ESC (see page 9).
If the power light on the transmitter is not turning on, first
ensure the batteries are installed correctly. You should also
check that the batteries are good and/or if rechargeable are
fully charged. Replace them if needed. If the power light is
blinking, then the transmitter batteries are weak and should
be replaced. If the transmitter light is on but the radio is still
not responding, you may need to rebind the transmitter to the
receiver. Please see page 14
Check to see if the ESC is in Forward only mode that does not
have reverse active.
Keep stripping spur gears:
Improper gear mesh, refer to page 19.
Improperly adjusted slipper, refer to page 18.
Short radio range:
If the radio range appears short, make sure the batteries are all
fully charged and/or are in good condition.
Steering works but the motor will not run:
The speed control may have gotten too hot and thermally
shut down. Allow time for the speed control to cool. If this is
the problem and has happened a few times, consider using a
smaller pinion or a larger spur gear.
Check the transmission, do the rear wheels spin easily?
Check that a motor wire has not come loose.
Verify that the electronic speed control is plugged into the
throttle channel of the receiver.
Check using another battery. Contact Horizon support for
service instructions.
Steering servo does not work:
Check all wires, radio system, battery connectors, and the
battery pack.
Contact Horizon support for service instructions.
Motor runs backwards:
The Black wire lead from the motor should be connected to the
Black wire lead from the ESC and the same for the Red wires.
If not, please correct by swapping the wires. If you are still
experiencing problems please contact Horizon support.
Motor starts running immediately after the battery has
been connected.
There may be internal ESC damage. Contact Horizon
Customer Support.
