• Always use new batteries for the radio system.
limit the radio signal between the receiver and the transmitter.
Loss of the radio signal can cause you to lose control of your
model.
• In order for the transmitter and receiver to bind to one another,
the receiver in the model must be turned on within 20 seconds
of turning on the transmitter. The transmitter LED will flash fast
red, indicating a failure to link. If you miss it, simply turn off the
transmitter and start over.
• Always turn on the transmitter before plugging in the battery.
RADIO SYSTEM BASIC ADJUSTMENTS
Steering Trim
The electronic steering trim located on the
face of the transmitter adjusts the neutral
(center) point of the steering channel.
Note: Traxxas Stability Management (TSM) must be completely
turned off while adjusting steering trim. See page 17 for TSM
adjustments.
Multi-Function Knob
The Multi-Function knob can be
programmed to control a variety of
functions. From the factory, the Multi-
Function knob controls Traxxas Stability Management (TSM).
For more detail on TSM, refer to page 17.
USING THE RADIO SYSTEM
The TQi Radio System has been pre-adjusted at the factory. The
adjustment should be checked before running the model in case
of movement during shipping. Here's how:
1. Turn the transmitter switch on. The status LED on the
transmitter should be solid green (not flashing).
2. Elevate the model on a block or a stand so that all the tires
are off the ground. Make sure your hands are clear of the
moving parts of the model.
3. Plug the battery pack in the model into the speed control.
4. The on/off switch is integrated into the speed control. With
the transmitter on, press and release the EZ-Set button (.25
seconds). The LED will shine RED (see note below). This turns
the model on. To turn the VXL-3s off, press and hold the EZ-Set
TRAXXAS TQ
Weak batteries will
button until the LED turns off (.5 seconds). Note: If the LED
shines green, Low-Voltage Detection is activated. This will
cause erratic performance from NiMH battery packs. The default
factory setting is for Low-Voltage Detection to be disabled
(LED shines red). Make sure to turn the low voltage detection
on when using LiPo batteries. Never use LiPo batteries while
Low-Voltage Detection is turned off. See page 18 for more
information.
5. Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak batteries.
6. When looking down at the
model, the front wheels
should be pointing straight
ahead. If the wheels are
turned slightly to the left or
right, turn off TSM
(see page 17) and slowly adjust the steering trim control on the
transmitter until they are pointing straight ahead; then, return
the multi-function knob to the desired TSM setting.
7. Gently operate the throttle trigger to ensure that you have
forward and reverse operation, and that the motor stops when
the throttle trigger is at neutral. Warning: Do not apply full
throttle in forward or reverse while the model is elevated.
8. Once adjustments are made, turn off the receiver on your
model, followed by the hand-held transmitter.
Range-Testing the Radio System
Before each running session with your model, you should range-
test your radio system to ensure that it operates properly.
1. Turn on the radio system and check its operation as described
in the previous section.
2. Have a friend hold the model. Make sure hands and clothing are
clear of the wheels and other moving parts on the model.
3. Walk away from the model with the transmitter until you reach
the farthest distance you plan to operate the model.
4. Operate the controls on the transmitter once again to be sure
that the model responds correctly.

Remember, always turn the
TQi transmitter on first and
off last to avoid damage to
your model.
Automatic Fail-Safe
The TQi transmitter and
receiver are equipped with
an automatic fail-safe system
that does not require user
programming. In the event
of signal loss or interference,
the throttle will return to
neutral and the steering will
hold its last commanded
position. If the fail-safe
system activates while you
are operating your model,
determine the reason for
signal loss and resolve the
problem before operating
your model again.
Stop immediately at the first
sign of weak batteries. Never
turn the transmitter off when
the battery pack is plugged
in. The model could run out
of control.
