ADVANCED TUNING GUIDE
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 16. The following items
can be adjusted most easily using your mobile device with the Traxxas Link
Wireless Module and the Traxxas Link App (see page 12).
Your Traxxas transmitter has a programmable Multi-Function knob that
can be set to control various advanced transmitter functions (set to
Traxxas Stability Management (TSM) by default, see page 8). Experiment
with the settings and features to see if they can improve your driving
experience.
Steering Sensitivity (Exponential)
The Multi-Function knob on the TQi transmitter can be set to control
Steering Sensitivity (also known as exponential). The standard setting
for Steering Sensitivity is "normal (zero exponential)," with the dial full
left in its range of travel. This setting provides linear servo response:
the steering servo's movement will correspond exactly with the input
from the transmitter's steering wheel. Turning the knob clockwise
from center will result in "negative exponential" and decrease steering
sensitivity by making the servo less responsive near neutral, with
increasing sensitivity as the servo nears the limits of its travel range.
The farther you turn the knob, the more pronounced the change in
steering servo movement will be. The term "exponential" comes from
this effect; the servo's travel changes exponentially relative to the
input from the steering wheel. The exponential effect is indicated as
a percentage—the greater the percentage, the greater the effect. The
illustrations below show how this works.
Normal Steering Sensitivity (0%
exponential):
In this illustration, the steering servo's
travel (and with it, the steering motion
of the model's front wheels) corresponds
precisely with the steering wheel. The
ranges are exaggerated for illustrative
purposes.
Decreased Steering Sensitivity (Negative
Exponential):
By turning the Multi-Function knob
clockwise, the steering sensitivity of the
model will be decreased. Note that a
relatively large amount of steering wheel
travel results in a smaller amount of servo
travel. The farther you turn the knob, the
more pronounced the effect becomes.
Decreased steering sensitivity may be
helpful when driving on low-traction
surfaces, when driving at high speed, or on tracks that favor sweeping turns where gentle
steering inputs are required. The ranges are exaggerated for illustrative purposes.
Throttle Sensitivity (Throttle Exponential)
The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity, but
applies the effect to the throttle channel. Only forward throttle is
affected; brake/reverse travel remains linear regardless of the Throttle
Sensitivity setting.
