Fail-Safe / Low-Voltage Detect
Consistent low voltage in the receiver triggers Fail-Safe so there is enough
power to center the throttle servo before it completely loses power.

ADVANCED TUNING GUIDE
Available Tuning Adjustments
The following items can be adjusted most easily using your mobile
device and the Traxxas Link application. All the features described
below may also be accessed using the MENU and SET buttons on
the transmitter and observing signals from the LED. An explanation
of the menu structure follows on page 35.
Your Traxxas transmitter has a programmable Multi-Function knob
that can be set to control various advanced transmitter functions
(set to Traxxas Stability Management (TSM) by default, see page 15).
Experiment with the settings and features to see if they can improve
your driving experience.
Steering Sensitivity (Exponential)
The Multi-Function knob on the TQi transmitter can be set
to control Steering Sensitivity (also known as exponential).
The standard setting for Steering Sensitivity is “normal (zero
exponential),” with the dial full left in its range of travel. This setting
provides linear servo response: the steering servo’s movement will
correspond exactly with the input from the transmitter’s steering
wheel. Turning the knob clockwise from center will result in
“negative exponential” and decrease steering sensitivity by making
the servo less responsive near neutral, with increasing sensitivity
as the servo nears the limits of its travel range. The farther you
turn the knob, the more pronounced the change in steering servo
movement will be. The term “exponential” comes from this effect;
the servo’s travel changes exponentially relative to the input
from the steering wheel. The exponential effect is indicated as a
percentage—the greater the percentage, the greater the effect.
The illustrations below show how this works.
Normal Steering Sensitivity
(0% exponential):
In this illustration, the steering
servo’s travel (and with it, the
steering motion of the model’s
front wheels) corresponds
precisely with the steering wheel.
The ranges are exaggerated for
illustrative purposes.
Throttle Trim Seek Mode
When the Multi-Function knob is
set to throttle trim, the transmitter
remembers the throttle trim setting. If
the throttle trim knob (Multi-Function
knob) is moved from the original
setting while the transmitter is off,
or while the transmitter was used to
control another model, the transmitter
ignores the actual position of the trim
knob. This prevents the model from
accidentally running away. The LED on
the face of the transmitter will rapidly
blink green and the throttle trim knob
(Multi-Function knob) will not adjust the
trim until it is moved back to its original
position saved in memory. To restore
throttle trim control, simply turn the
Multi-Function knob either direction
until the LED stops blinking.
Fail-safe
Your Traxxas radio system is equipped
with a built-in fail-safe function that
returns the throttle to its last saved
neutral position in the event of a signal
loss. The LED on the transmitter and the
receiver will rapidly flash red.
Starting Over:
Restoring Factory Defaults
When programming your TQi transmitter,
you may feel the need to start over with a
clean slate. Follow these simple steps to
restore the factory settings:
1. Turn the transmitter off.
2. Hold both MENU and SET.
3. Turn the transmitter on.
4. Release MENU and SET. The
transmitter LED will blink red.
5. Press SET to clear settings. The
LED will turn solid green and the
transmitter is restored to default.
