3. When the transmitter and receiver's LEDs turn solid green, the
system is bound and ready for use. Confirm that the steering and
throttle operate properly before driving your model.
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, 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 model's handling is the "right setting."
SETTING UP THE ANTENNA
The receiver antenna has been set up and installed from the
factory. The antenna is secured by a 3x4mm set screw. To remove
the antenna tube, simply remove the set screw with the included
1.5mm wrench.
When reinstalling the antenna, first slide the antenna wire into
bottom of antenna tube until white tip of antenna is at top of tube
under the black cap. Next insert
the antenna tube into the mount
while making sure that antenna
wire is in slot in the antenna mount,
then install the set screw next to
the antenna tube. Use the supplied
1.5mm wrench to tighten the screw
just until the antenna tube is securely
in place. Do not over tighten. Do not
bend or kink the antenna wire! See the
side bar for more information. Do not
shorten the antenna tube.

To prevent loss of radio

the end of the metal tip.
