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. P ress 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. P ress and hold the receiver's LINK button as you switch the model
on. Release the LINK button.
3. W hen the transmitter's 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."
