ADVANCED TUNING GUIDE

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 vehicle) 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.

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.

Braking Percentage

R/C boats do not have brakes, as the natural resistance of the water will
slow and stop the boat when the throttle is shut off; however, if you
use your TQi transmitter with a car or truck, you may find the Braking
Percentage function useful. When set for Braking Percentage, the Multi-
Function knob will control the amount of brake travel applied by the
throttle/brake 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 full clockwise will deliver maximum brake throw; turning the knob
counter-clockwise reduces brake throw.

Note

: Turning the dial counter-

clockwise to its stop will eliminate all brake action.

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.
