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.

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
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.
