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 another
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 the
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 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 the left 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 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. Insert the base of the tube into
the antenna post. Take care not to crimp
the antenna wire. Slide the crimp nut
over the antenna tube and screw it onto
the antenna post. Use the supplied tool
to tighten the crimp nut on the post just
until the antenna tube is securely in place.
Do not over tighten or crush the antenna
wire against the chassis.
Do not bend or
kink the antenna wire! See the sidebar
for more information. Do not shorten the
antenna tube. The minimum height is
62mm.
