6. Turn off the vehicle and then the transmitter.
7. Remove the bind plug from the receiver.
8. Turn on the transmitter and then the vehicle to ensure
operation. If the transmitter does not control the vehicle, repeat
steps 1 –7 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-SCT 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-SCT
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-SCT 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-SCT 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-SCT 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 12RB 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-
SCT 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-SCT
•
Periodically examine your XXX-SCT 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-SCT, 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.
