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.
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.

The recommended (default)
setting for TSM is to rotate the
knob to the 12:00 position (the
zero mark on the dial).
Turn the knob clockwise to
increase assistance; turn the knob
counterclockwise to decrease
assistance. Turn the knob
counterclockwise to its stop to
turn TSM completely off.

assistance
When driving on surfaces with
some traction, decrease the TSM
TSM off
setting to allow the vehicle to
feel more "loose". On surfaces
with very little traction (loose
dirt, smooth concrete, ice/snow), increase TSM to maximize acceleration
and control. TSM should be disabled when precise wheel placement is
needed, such as during rock crawling or scaling extreme terrain.
Note: TSM must be completely turned off while adjusting steering trim.

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
Recommended setting
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
Increase
steering or throttle servo in the event that simply setting the trim knob
assistance
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.
