Steering Sensitivity (Exponential)
The Multi-Function knob on the TQi transmitter has been
programmed 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,
TRAXXAS TQ
or on tracks that favor sweeping turns where gentle steering inputs
are required. The ranges are exaggerated for illustrative purposes.

Experiment! Try varying degrees of exponential. It's easy to go
back to "zero" if you don't like the effect. There's no wrong way to
adjust exponential. Any setting that makes you more comfortable with
your car's handling is the "right setting."
SETTING UP THE ANTENNA
The receiver antenna has been set up
and installed from the factory.
When installing the antenna, first slide
the antenna wire into the bottom of
the antenna tube until the white tip of
the antenna is at the top of the tube
under the black cap. Insert the base of
the tube into the antenna post. Take
care not to crimp the antenna wire.
Slide the crimp nut over the antenna
tube and screw it onto the antenna
post. Use the supplied tool to tighten
the crimp nut on the post just until the
antenna tube is securely in place. Do
not overtighten or crush the antenna
wire against the chassis. Do not bend or
kink the antenna wire! See the sidebar
for more information. Do not shorten the
antenna tube.

To prevent loss of radio range
do not kink or cut the black wire,
do not bend or cut the metal tip,
and do not bend or cut the white
wire at the end of the metal tip.
