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 TQ 2.4GHz transmitter has been
programmed to control Steering Sensitivity (also known as
exponential). The standard setting for Steering Sensitivity is “50%
negative exponential” with the dial in the middle of its travel
range (pointer straight up). Turning the knob clockwise will further
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 to the right
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. The transmitter included with the
Traxxas Rally has been set at the factory for decreased steering
sensitivity. 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.”

Range on Model
Steering exponential can
help make the model
easier to drive. Turning the
transmitter’s multi-function
knob clockwise (when set
for Steering Sensitivity) will
decrease sensitivity, making
the model less responsive
when initiating a turn.
Reducing steering sensitivity
may also help you maintain
a controlled slip angle when
countersteering through a
drift-turn. Experiment with
the setting to nd what
works best for you.
