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. Reducing steering throw can also be useful in making a model
easier to control on high-traction surfaces, and limiting steering
output for oval racing where large amounts of steering travel are
not required.
Braking Percentage
The Multi-Function knob may also be set to control the amount
of brake travel applied by the servo in a nitro-powered model.
Electric models do not have a servo-operated brake, but the
Braking Percentage function still operates the same way in electric
models. Turning the Multi-Function knob fully clockwise will deliver
maximum brake throw; turning the knob counterclockwise reduces
brake throw (
Note
: Turning the dial counterclockwise to its stop will
eliminate all brake action).
Throttle Trim
Setting the Multi-Function knob to serve as throttle trim will allow
you to adjust the throttle’s neutral position to prevent unwanted
brake drag or throttle application when the transmitter trigger is
at neutral.
Note
: Your transmitter is equipped with a Throttle Trim
Seek mode to prevent accidental runaways. See the sidebar for
more information.
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.
TRAXXAS LINK MODEL MEMORY
Traxxas Link Model Memory is an exclusive, patent-pending feature
of the TQi transmitter. Each time the transmitter is bound to a
new receiver, it saves that receiver in its memory along with all
the settings assigned to that receiver. When the transmitter and
any bound receiver are switched on, the transmitter automatically
recalls the settings for that receiver. There is no need to manually
select your vehicle from a list of model memory entries.
Model Lock
The Traxxas Link Model Memory feature can store up to thirty
models (receivers) in its memory. If you bind a thirty-first receiver,
Traxxas Link Model Memory will delete the “oldest” receiver from
its memory (in other words, the model you used the longest time
ago will be deleted). Activating Model Lock will lock the receiver in
memory so it cannot be deleted.
You may also bind multiple TQi transmitters to the same model
making it possible to pick up any transmitter and any previously
bound model in your collection and simply turn them on and drive.
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.
