• Always use new or freshly charged batteries for the radio system.
Weak batteries will 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
Throttle Neutral Adjustment
The throttle neutral adjustment is located
on the transmitter face and controls the
forward/reverse travel of the throttle
trigger. Change the adjustment by
pressing the button and sliding it to the
desired position. There are two settings
available:
50/50: Allows equal travel for both acceleration and reverse.
70/30: Allows more throttle travel (70%) and less reverse
travel (30%).
Note: We strongly recommend to leave this control in its factory
location until you become familiar with all the adjustments
and capabilities of your model. To change the throttle neutral
adjust position, turn the transmitter off before adjusting the
neutral position. You will need to reprogram your electronic
speed control to recognize the 70/30 setting. Turn to ESC Setup
Programming on page 16 for instructions.
Steering Trim
The electronic steering trim located on the
face of the transmitter adjusts the neutral
(center) point of the steering channel.
Multi-Function Knob
The Multi-Function knob can be
programmed to control a variety of
functions. From the factory, the Multi-
Function knob controls steering sensitivity,
also known as exponential or "expo." When the knob is turned

counterclockwise all the way to the left (default position), expo is
off and steering sensitivity will be linear (the most commonly used
setting). Turning the knob clockwise will "add expo" and decrease
the steering sensitivity in the initial range of steering wheel travel
left or right from center. For more detail on steering exponential,
refer to page 15.
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
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 the included NiMH battery
pack. 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
16 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, slowly adjust the
steering trim control on the
transmitter until they are pointing straight ahead.
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.
