THE TQ 2.4GHz RADIO SYSTEM
Range-Testing the Radio System
Before each
running session
with your model, you should
range-test your radio system to
ensure that it operates properly.
1. Turn on the radio system
and check its operation as
described in the previous
section.
2. Have a friend hold the model
with the engine off.
3. Make sure your transmitter
antenna is straight up, and
then walk away from the
model with the transmitter
until you reach the farthest
distance you plan to operate
the model.
4. Operate the controls on the transmitter once again to be sure that
the model responds correctly.
5. Do not attempt to operate the model if there is any problem with
the radio system or any external interference with your radio signal
at your location.
Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will near the
limit of radio range. At 60mph, a model can cover 88 feet every
second! It's a thrill, but use caution to keep your model in range. If
you want to see your model achieve its maximum speed, it is best
to position yourself in the middle of the truck's running area, not
the far end, so you drive the truck towards and past your position.
In addition to maximizing the radio's range, this technique will
keep your model closer to you, making it easier to see and control.
No matter how fast you drive your model, always leave adequate
space between you, the model, and others. Never drive directly
toward yourself or others.
TQ 2.4GHz Binding Instructions
For proper operation, the transmitter and receiver must be
electronically 'bound.' This has been done for you at the factory.
Should you ever need to re-bind the system or bind to an additional
transmitter or receiver, follow these instructions. Note: the receiver
must be connected to a 4.8-6.0v (nominal) power source for binding
and the transmitter and receiver must be within 5 feet of each other.
1. Press and hold the transmitter's SET button as you switch
transmitter on. The transmitter's LED will flash red slowly.
Release the SET button
2. Press and hold the receiver's LINK button as you switch on the speed
control by pressing the EZ-Set button. Release the LINK button.
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 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 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.
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. 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.
