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 29.
Your Traxxas transmitter has a programmable Multi-Function knob
that can be set to control various advanced transmitter functions
(set to Steering Sensitivity by default, see page 14). Experiment with
the settings and features to see if they can improve your driving
experience.
Steering Percentage (Dual Rate)
The Multi-Function knob can be set to control the amount
(percentage) of servo travel applied to steering. Turning the Multi-
Function knob fully clockwise will deliver maximum steering throw;
turning the knob counter-clockwise reduces steering throw (note:
turning the dial counter-clockwise to its stop will eliminate all servo
travel). Be aware that the steering End Point settings define the
servo’s maximum steering throw. If you set Steering Percentage to
100% (by turning the Multi-Function knob fully clockwise), the servo
will travel all the way to its selected end point, but not past it. Many
racers set Dual Rate so they have only as much steering throw as
they need for the track’s tightest turn, thus making the car easier to
drive throughout the rest of the course. Reducing steering throw
can also be useful in making a car easier to control on high-traction
surfaces, and limiting steering output for oval racing where large
amounts of steering travel are not required.
Throttle Sensitivity (Throttle Exponential)
The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity as
described on page 14, but applies the effect to the throttle channel.
Only forward throttle is affected; brake/reverse travel remains linear
regardless of the Throttle Sensitivity setting.
Steering and Throttle End Points
The TQi transmitter allows you to choose the limit of the servo’s
travel range (or its “end point”) independently for left and right
travel (on the steering channel) and throttle/brake travel (on the
throttle channel). This allows you to fine-tune the servo settings to

ADVANCED TUNING GUIDE
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 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.
Failsafe
Your Traxxas radio system is equipped
with a built-in failsafe 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 transmitter off.
2. Hold both MENU and SET.
3. Turn transmitter on.
4. Release MENU and SET. The
transmitter LED will blink red.
5. Press MENU 3 times. LED will blink red
4 times repeatedly.
6. Press SET to clear settings. The
LED will turn solid green and the
transmitter is restored to default.
