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 rudder)
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 your model at high speeds, or
anytime a less aggressive steering feel is desired.
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! 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.
