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 car’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 the bottom
of the antenna tube until the white tip
of the antenna is at the top of the tube
under the black cap. Next, insert the
antenna tube into the mount while
making sure that the antenna wire
is in the 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
overtighten.
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.
