ELECTRONIC SPEED CONTROL
RADIO SYSTEM MODEL 2204 ONLY
The Traxxas XL-1 electronic speed control is a fully-proportional,
forward/reverse unit. It has two adjustments; the neutral control
and the proportional control. Use a small screwdriver to adjust the
controls.
CAUTION: The adjustment controls will only turn
1/4 turn left or right from center. Do not turn the
controls past their stops or they will break. Use a
light touch when making adjustments. Controls
damaged by overturning them past their stops will
not be covered under the warranty.
• Adjusting the neutral control:
First, set the model on its
stand, turn on the transmitter, and plug a fresh battery pack into
the speed control. Set the throttle trim on the transmitter to the
“0” mark. If the motor is running, gently turn the neutral control
right or left until the motor stops running and the L.E.D. is off
(neither green or red).
• Adjusting the proportional control:
After setting the neutral
control, move the throttle trigger on the transmitter to full throttle.
Now, carefully adjust the proportional control right or left until the
motor is running at its fastest speed and there is a strong green
light emitted from the L.E.D. If the L.E.D. glows red instead of
green, then switch the throttle servo reversing switch on the face
of the transmitter.
Install the electronic speed control in the model where air can
pass over the fins of the aluminum heatsink.
PRECAUTIONS:
• The radio system is not waterproof. Avoid driving through pud-
dles, wet grass, or mud. If water gets into the electronics it
could damage them.
• Do not continue to operate the model with low batteries or you
could lose control of it. After the battery power drops below a
certain point, the model will continue out of control with the last
command it had from the transmitter. Indications of low battery
power include slow operation, sluggish servos and, for the
transmitter, a flashing red light. When using nicad batteries, be
especially alert for signs of weak batteries. Stop immediately at
the first sign of weak batteries.
• Radio-controlled models are subject to radio interference from
many sources beyond your control. Since radio interference can
cause momentary losses of control, allow a safety margin of
space in all directions around the model to prevent collisions.
• If the transmitter is too close to the receiver (within 3-feet), you
may experience erratic radio system operation.
• Flourescent lighting and steel building structures have been
known to cause radio interference.
• Hold the steering wheel with just your fingertips! If you grip
the wheel with your entire hand, you might then be able to
exert enough force to break the steering mechanism by over-
turning. Overturning the wheel is not covered by warranty.
TROUBLESHOOTING:
Most problems with radio controlled models can be traced to a
few commonly overlooked areas. Below is a list of items to check
if your model appears to be completely dead, have short range,
or have intermittent control. If all of the items check out okay and
the radio system is still malfunctioning, then call the Traxxas service
line at 1-888-TRAXXAS.
Check to be sure that all of the batteries are either fresh or fully
charged, and that they are installed correctly as indicated in the
battery holders.
Check the on/off switches, both on the transmitter and in the
model (if equipped), for proper operation.
Make sure the receiver antenna is fully extended and is not broken
or shorted. Make sure the transmitter antenna is screwed down
snugly and that the mast is fully extended.
Check all of the servo cables to be sure that they are securely
plugged into the receiver. Check all other wires to be sure they
are securely connected and do not have any kinks or breaks.
Make sure the crystals are in the right place and that they are
completely plugged in.
Make sure there are no other transmitters in your area operating
on the same frequency.
Make sure the radio system has not come in contact with water
or fuel.
WHEN RETURNING FOR SERVICE:
If your radio system malfunctions and you wish to return it for
repair, whenever possible remove the radio system from the
model and send it separately. Also, remove all of the batteries.
Return the unit(s) with a brief note describing the problem, plus a
daytime phone number and return address
