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. 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.

.
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.
TQi 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 model. 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 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.
When installing 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 antenna wire is in slot in the antenna
mount.
Do not bend or kink the antenna
wire! Do not shorten the antenna tube.
