Traxxas 6907 Owner's Manual page 12

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, or rechargeable
batteries such as NiMH (Nickel
Metal Hydride) batteries in
your transmitter. Make sure
rechargeable batteries are
fully charged according to the
manufacturer's instructions.
If you use rechargeable
batteries in your transmitter,
be aware that when they begin
to lose their charge, they lose
power more quickly than
regular alkaline batteries.
Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red
light) to avoid losing control.
When rechargeable batteries
begin to lose their charge,
they will fade much faster
than alkaline dry cells. 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.

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 ESC Setup
Programming on page 14 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"

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.
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.
The model is now ON.
4. 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.
5. 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.
6. 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.
7. Once adjustments are made, unplug the model first, and then
turn off the transmitter.
