Troubleshooting Guide - Team Losi XXX-SCT Instruction Manual

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, contact the appropriate Horizon product
support center (see page 13).
Radio system does not work properly
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 6.
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.
Symptom
Steering servo operates but the motor does not run
Steering and motor do not function
Full speed not attainable
Motor slows but will not stop
Reduced radio range/Interference

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.
Vehicle runs slowly/slow acceleration
Check battery connectors.
Confirm battery is charged.
Vehicle will not reverse
Make sure the throttle trim is at neutral.
Recalibrate/Setup the ESC (see page 5).
Check to see if the ESC is in Forward only mode that does
not have reverse active.
Keep stripping spur gears
Improper gear mesh: Make sure mesh engages all teeth but
is not too tight causing binding.
Improperly adjusted slipper: Slipper should slip for first 1-2 feet.
If it is too tight, loosen. If too loose tighten and re-check.

programming instructions.
Speed control connected to receiver incorrectly.
