Re-Binding the Transmitter
to the Receiver
The Losi DSM radio system included in the Mini SCT
operates on 2.4GHz. The communication between the
transmitter and receiver starts in the few seconds after the
transmitter and vehicle are both turned on. This is called
the “binding process”. The Losi DSM radio system will not
interfere with previous technology radio systems that operate
on 27MHz or 75MHz frequencies and you will not receive any
interference from them. Although set at the factory, below are
the steps required to re-bind your transmitter to the receiver
should the need arise. During the bind process there is a
unique ID from the transmitter communicated to the receiver
to ensure trouble-free radio operation.
Steps to Re-Bind
1. Ensure the transmitter and vehicle are both turned off.
2. Using the supplied Bind plug (which looks like a
standard receiver plug with a wire loop installed) insert
or plug into the receiver slot labeled “BIND”. Looking
down on the receiver this slot would be below the LED
and is the furthest from the LED, or nearest to the corner
of the receiver.
Note: You do not need to remove any
of the other plugs to re-bind.
3. With the Bind plug installed, turn on the vehicle. Notice a
blinking Orange LED within the receiver.
4. Now you are ready to turn on the transmitter. You should
notice on the back of the transmitter a similar blinking
Orange LED under the translucent cover.
5. Both the receiver and transmitter blinking Orange LEDs
will stop blinking and become solid indicating they have
“bound” themselves together.
6. Please turn off both the vehicle and transmitter to
remove the Bind plug from the receiver. Failing to
remove the Bind plug will cause the transmitter to
attempt to rebind every time you turn on the vehicle and
transmitter.
7. Turn on both the vehicle and transmitter to ensure
operation. If the transmitter does not control the vehicle,
please repeat steps 1 to 6. Should this not correct the
problem please call Horizon Service/Repair for further
assistance.
8. The Bind process is complete. Your vehicle’s radio
system should be ready for use.

Chassis Tuning
The Mini SCT has several adjustments available to you for
tuning the performance for your needs. Although there are
multiple shock positions and camber link locations provided,
we have built the model with the best overall settings. The
following are simple adjustments and easily maintained
settings to assure proper operation and performance. It is
advised when making any adjustment that you do so in small
increments and always check for other parts of the chassis
that are affected.
Slipper Adjustments
The Mini SCT is equipped with a slipper device offering
both traction control and protection for the transmission.
The slipper is primarily used to help absorb sudden impacts
on the drivetrain due to landing big jumps or when using
more powerful aftermarket motors and/or battery packs.
Additionally, it can be used to smooth out the ow of power
to the rear wheels and limit wheel spin when running on
extremely slick surfaces.
When adjusted properly, you should be able to hold the rear
tires rmly and barely be able to push the spur gear forward
with your thumb.
To track test, turn the Mini SCT on and place it on the
ground. As you push it backwards allowing it to roll freely,
punch the throttle. The slipper should slip no more than an
inch or two as it accelerates. With the included motor and
battery pack it should slip just a little. Make sure you replace
the gear cover before running.
Steering Rate
Your transmitter is equipped with a steering rate control to
the left of the steering wheel. This advanced feature, usually
found only on competition-type radios, allows you to adjust
the amount the front tires move when you turn the steering
wheel. This is really helpful when you are on slick, as well as
high-traction surfaces.
Less Rate
Increase
Slip
Reduce
Slip
Adjustment is made by turning the 3mm adjustment nut
clockwise (to the right) to reduce the slip, or counterclockwise
(to the left) to increase the slip.
8 - EN
If your Mini SCT turns too sharply and/or spins out easily,
try turning the steering rate down by rotating the knob
counterclockwise (to the left).
Page 9
More Rate
For sharper or additional steering, try turning the knob
clockwise (to the right).
Toe-In
This is the relationship of the left and right side tire to one
another.
Camber
Camber is the angle of the tires to the racing surface when
viewed from the front or rear of the truck.
Less Camber More Camber
You want to keep both the front and rear tires straight up and
down or leaning in at the top very slightly.
If you are running on carpet or similar high traction surfaces,
you may nd leaning the tires in a bit more helps. This
adjustment is made with the threaded links extending from
the front or rear bulkhead to the spindle carrier or rear hub.
Making the camber rods shorter increases the camber and
lean-in of the tire, while making the camber rods longer
decreases the camber.
Less Toe-In More Toe-In
Ideally, you want the front of the tires to be pointed inward
toward each other just slightly when viewed from above. This
makes the model track straight and stable. This is controlled
with the threaded steering rods on either side. As you make
them longer you will increase the toe-in and vice versa.
Ride Height
This is the height the chassis sits and runs at. Spring spacers
included with the Mini SCT, when installed between the
shock top and spring, will increase the pre-load on the spring
and raise the chassis. You may want to try this when running
on extremely rough surfaces.
Service/Repair
Radio/Speed Control & Motor
If you have any problems other than those covered in
the troubleshooting section, please call the appropriate
electronics service department. They will be able to give your
specic problem additional attention and instruct you as to
what needs to be done.
Maintenance
If you have any questions other than those covered in the
troubleshooting or maintenance sections, please call the
appropriate Horizon product support department.
Cleaning
Performance can be hindered if dirt gets in any of the moving
suspension parts. Use compressed air, a soft paintbrush, or
toothbrush to remove dust or dirt. Avoid using solvents or
chemicals as they can actually wash dirt into the bearings or
moving parts as well as cause damage to the electronics.

Rebuilding the Differential
Reassembly
The gears in the differential will wear over time. The same
is true for the outdrives, driveshafts, and rear axles. We
suggest using a small rag or paper towel to lay out the parts
you remove to make it easier to reassemble.
Disassembly
1. Unplug the 3 motor wires from ESC.
2. Remove the gear cover (three screws pictured)
3. Remove the 2 screws on the front of the rear shock
tower that attach to the rear upper cage. Once the
screws are removed, rotate the rear cage toward the
rear enabling access to the rear camber block.
4. Remove the 2 screws attaching the rear camber block to
the transmission case.
5. Remove 4 screws from rear skid plate and remove
transmission from vehicle.
6. Remove bracket on top of transmission by removing the
2 front screws and removing the long screw (secured
with a bolt), which passes through the transmission from
the motor plate side.
7. Remove the left side of the gearbox by removing the
three screws.
8. Remove any shims on the bevel gears (not used on all
models) and set them aside so they can be reinstalled in
the same location.
9. Carefully remove the large plastic sun gear and the
bevel gears on either side of it. You can use the
removed differential assembly as a guide for putting
together the replacement unit. For the best performance
Losi Grease (LOSA3066) can be applied to these gears.
10. Remove the center mounted idler gear from the
gearbox. Remove the shaft and push the ball bearings
out of both sides. Install these bearings in the new gear.
Replace the idler gear and shaft into the center of the same
right side of the gearbox. Replace any shims removed from
the right bevel gear and slide it through the lower bearing.
Replace any shims that came off of the left side bevel gear
and allow it to slide through the lower bearing as you put the
left gearbox half back into position. Replace the screws and
reinstall the rebuilt gearbox using the above steps in reverse
order. Consult the exploded view in the back of this manual
for more details.
Changing the Spur Gear
Remove the gear cover by removing the three small screws.
If you are replacing the spur gear with one of a different size
(number of teeth), you must rst loosen (do not remove) the
two screws that secure the motor and slide it back slightly.
Remove the 3mm nut at the end of the slipper shaft and all
of the slipper parts on the outside of the spur gear as well
as the old gear. Place the new spur gear into position and
replace the slipper parts. If you have changed the size of
the spur, see Setting the Gear Mesh below. After you have
changed the spur gear, you will have to adjust the slipper as
described elsewhere.
Changing the Pinion Gear/Gear Ratio
Before you change the pinion gear ask yourself why you are
doing it. In general, if you change to a larger pinion the top
speed will improve but you will see less acceleration and
run time. This would only be advisable for really long track
layouts with few tight turns. Changing to a smaller pinion
will give you quicker acceleration and possibly a bit longer
run time but a little less top speed. This would be good for
short layouts or when running hotter motors. The pinion on
the Mini SCT offers the best balance of both. To change the
pinion, remove the gear cover, loosen the motor screws, and
slide the motor back. Use a pair of small needle-nose pliers
between the motor plate and back of the pinion to push the
pinion off. Place the new pinion on the end of the motor shaft
and, using the at of the pliers or a similar at tool, push it
on to the same position as the one removed. See Setting the
Gear Mesh below.
CAUTION: When running aftermarket motors, check
with the motor manufacturer for correct gearing. Never
over-gear the motor as it can cause overheating, damaging it
and the speed control.
Setting the Gear Mesh
The motor screws should be slightly loose. Slide the motor
forward allowing the pinion gear to mesh with the spur gear.
Snug (not tight) the bottom motor screw and try rocking the
spur back and forth. There is a slight bit of movement before
the motor is forced to turn over. If not, pull the top of the
motor back slightly and recheck. If there is too much slop
between the gears, push the top of the motor forward. When
set properly, the wheels can be spun forward freely with
very little noise. Make sure to tighten both motor screws and
replace the gear cover before running.

Steering Servo Installation/Removal
Unplug the servo lead from the receiver. Remove the four
small screws located on the bottom of the chassis that
secure the servo to the chassis. Use a screwdriver or small
pliers to pop the steering link off of the servo, so it can be
removed. Replace in the reverse sequence used to remove
the servo.
Receiver/Speed Control (ESC)
Installation/Removal
Unplug the power lead, motor leads and steering servo. Do
not attempt to open the receiver or electronic speed control
(ESC) as only a factory technician has the proper tools
and parts to make any repairs necessary. The receiver and
ESC are mounted with double-sided foam tape. Use your
thumb and index nger at the bottom of the front corners
to pull them from the mount. If this is difcult, ask for help.
If necessary, carefully use a large at blade screwdriver
between the unit and the mount to pry it loose. Make
sure you remove any left over foam or adhesive before
remounting with common servo tape or hobby type foam
tape.

Rebuilding/Refilling the Shocks
Step 1
After removing the shock,
push up on the lower spring
cup and remove it from the
shaft. Remove the spring and
preload spacers.
Step 2
Turn the shock upside down
and remove the black shock
cartridge/shaft assembly
from the shock body by
turning it counterclockwise.
Note: If you only wish to
change or fill the shock fluid,
skip to step 5.
Step 5
If you plan on completely
changing the shock fluid
(suggested), dump out the
old fluid from the shock body.
Carefully fill the shock body
with fluid to the bottom of the
threads inside the shock body.
Step 6
Pull the shaft out so the
piston is next to the
cartridge and reinstall the
assembly into the shock
body. Turn in a clockwise
direction until snug—DO NOT
TIGHTEN yet!
Step 3
Remove the top E-clip from the
shock shaft. Remove the shock
piston. Remove second E-clip.
Remove the old cartridge.
Put a drop of oil on the shock
shaft before installing a new shock
cartridge.
Step 4
Reinstall the lower E-clip.
Slide the shock piston onto
the shock shaft against the
E-clip. Reinstall the top E-clip.
Step 7
Turn the shock over and use a #0 Phillips
screwdriver to remove the small bleed
screw at the top of the shock. Slowly push
the shock shaft up until it stops. Excess fluid
should flow out of the bleed hole. Slowly pull
the shock shaft halfway back and replace
the bleed screw. Use pliers to tighten the
cartridge, being careful not to strip the
plastic lobes on the cartridge.
Step 8
Replace the spring and
spring cup and test the shock
action for smoothness and
leaks. Retighten the bleed
screw or cartridge if either
leaks. Remount the shock on
your truck.
Note: Production shocks may differ slightly from those shown
in the drawings.
