Remember, always turn the
TQi transmitter on first and
off last to avoid damage to
your model.
Use the Right Batteries
Your transmitter uses AA
batteries. Use new alkaline
batteries. Do not use
rechargeable AA cells to power
the TQi transmitter, as they will
not provide sufficient voltage
for optimum transmitter
performance.
Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red
light) to avoid losing control.
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.

Installing the Battery Pack
1. Insert the battery into the tray
with the High-Current Connector
positioned towards the front of
the car.
2. Insert the hold-down into the
lower set of holes in the support.
3. Align the hold-down over the
retainer and press down until it
snaps into place.
4. When you are ready to drive,
connect the battery's High-
Current Connector to the speed control.
Note: The speed control does not have an on/off switch. Make
certain your transmitter is switched on and you are ready to operate
the model before plugging the battery into the speed control.
Removing the Battery Packs
1. Unplug the High-Current Connector.
2. Flex the retainer away from the battery.
3. Lift the battery hold-down up and remove the battery.
RADIO SYSTEM RULES
• Always turn your TQi transmitter on first and off last. This
procedure will help to prevent your model from receiving stray
signals from another transmitter, or other source, and running out
of control. Your model has electronic failsafes to prevent this type
of malfunction, but the first, best defense against a runaway model
is to always turn the transmitter on first and off last.
• 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.
• 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.
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 "Adjusting the
Electronic Speed Control" on page 17 for instructions.
Torque Control Setting (Multi-Function Knob)
The Multi-Function knob can be
programmed to control a variety of functions.
From the factory, the Multi-Function knob
controls the Torque Control setting. Torque Control allows you to
set the amount of torque limiting the speed control will provide.
The ideal setting will match the car's torque to the available traction,
so you can launch as quickly as possible without breaking traction
and spinning the tires. Slippery conditions require less torque; high-
traction conditions allow you to increase the torque setting.
Adjusting the Torque Control is simple. To increase torque, turn the
Multi-Function knob clockwise. Turning the knob to its stop will
result in zero torque limiting (maximum power). To reduce torque,
turn the Multi-Function knob counterclockwise. For racing, you will
typically adjust the Torque Control setting until you can launch
at full throttle without spinning the tires. See "Driving your Model"
Note: Extremely limited torque
on page 18 for more information.
settings will greatly inhibit vehicle performance and will make the
model behave as though its battery is low.
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 25 for TSM
adjustments.
