LED Color / Pattern Name Notes
Solid green Normal Driving Mode See page 15 for information on how to use your transmitter controls.
Slow red (0.5 sec on / 0.5 sec off) Binding See page 17 for more information on binding.
Flashing fast green (0.1 sec on / 0.15 sec off) Throttle Trim Seek Mode
Turn the Multi-Function knob right or left until the LED stops flashing.
See page 31 for more information.
Flashing medium red (0.25 sec on / 0.25 sec off) Low Battery Alarm Put new batteries in the transmitter. See page 13 for more information.
Flashing fast red (0.125 sec on / 0.125 sec off) Link Failure / Error
Transmitter and receiver are no longer bound. Turn the system off and then
back on to resume normal operation. Find source of the link failure (i.e., out of
range, low batteries, damaged antenna).
Programming Patterns
Counts out number (green or red), then pauses Current menu position See Menu Tree for more information.
Fast green 8 times Menu setting accepted (on SET)
Fast red 8 times Menu SET invalid User error, such as trying to delete a locked model.

Flashing fast red (0.125 sec on / 0.125 sec off) 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.

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 prevent binding
caused by the servo moving steering or throttle linkages (in the case
of a nitro model) farther than their mechanical limits. The end point
adjustment settings you select will represent what you wish to be the
servo’s maximum travel; the Steering Percentage or Braking Percentage
functions will not override the End Point settings.
Steering and Throttle Sub-Trim
The Sub-Trim function is used to precisely set the neutral point of the
steering or throttle servo in the event that simply setting the trim knob
to “zero” does not completely center the servo. When selected, Sub-Trim
allows finer adjustment to the servo output shaft’s position for precise
setting of the neutral point. Always set the Steering Trim knob to zero
before making final adjustment (if required) using Sub-Trim. If Throttle
Trim has been previously adjusted, the Throttle Trim will need to be
reprogrammed to “zero” before making final adjustment using Sub-Trim.
Setting Lock
Once you’ve adjusted all of these settings the way you like them, you
may want to disable the Multi-Function knob so none of your settings
can be changed. This is especially handy if you operate multiple vehicles
with a single transmitter via Traxxas Link
™
Model Memory.
Multiple Settings and the Multi-Function Knob
It is important to note that settings made with the Multi-Function
knob are “overlaid” on top of each other. For example, if you assign the
Multi-Function to adjust Steering Percentage and set it for 50%, then
reassign the knob to control Steering Sensitivity, the transmitter will
“remember” the Steering Percentage setting. Adjustments you make
to Steering Sensitivity will be applied to the 50% steering throw setting
you selected previously. Likewise, setting the Multi-Function knob to
“disabled” will prevent the knob from making further adjustments, but
the last setting of the Multi-Function knob will still apply.
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 on the
receiver will rapidly flash red.
In order to re-acquire the signal
after the failsafe has activated,
you will need to walk a longer
distance closer to the model than
the distance the model travelled
out of range. Simply keep walking
towards the model until you re-
acquire the signal.
