TQ 2.4GHz RADIO AND VELINEON POWER SYSTEM
Steering Sensitivity (Exponential)
The Multi-Function knob on the TQ2.4GHz 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! See the side bar 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.
