Available Tuning Adjustments
All the features described below may also be accessed using the menu
and set buttons on the transmitter and observing signals from the LED.
An explanation of the menu structure follows on page 14. The following
items can be adjusted most easily using your mobile device with the TQi
Docking Base and the Traxxas Link application, see page 11.
Your Traxxas transmitter has a programmable Multi-Function knob that
can be set to control various advanced transmitter functions (set to
Steering Sensitivity by default, see page 8). Experiment with the settings
and features to see if they can improve your driving experience.
Throttle Sensitivity (Throttle Exponential)
The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity as
described on page 8, but applies the effect to the throttle channel.
Only forward throttle is affected; brake/reverse travel remains linear
regardless of the Throttle Sensitivity setting.
Steering Percentage (Dual Rate)
The Multi-Function knob can be set to control the amount (percentage)
of servo travel applied to steering. Turning the Multi-Function knob
fully clockwise will deliver maximum steering throw; turning the knob
counter-clockwise reduces steering throw (note: turning the dial
counter-clockwise to its stop will eliminate all servo travel). Be aware
that the steering End Point settings define the servo’s maximum
steering throw. If you set Steering Percentage 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. Many racers set Steering
Percentage so they have only as much steering throw as they need
for the track’s tightest turn, thus making the model easier to drive
throughout the rest of the course. 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 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).
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 below for more information.
ADVANCED TUNING GUIDE
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.
