 ADVANCED TUNING GUIDE

Available Tuning Adjustments

The following items can be adjusted most easily using your mobile 
device and the Traxxas Link application. All the features described 
below may also be accessed using the MENU and SET buttons on 
the transmitter and observing signals from the LED. An explanation 
of the menu structure follows on page 36.
Your Traxxas transmitter has a programmable Multi-Function knob 
that can be set to control various advanced transmitter functions 
(set to Traxxas Stability Management by default, see page 16). 
Experiment with the settings and features to see if they can improve 
your driving experience.  

Steering Sensitivity (Exponential)

The Multi-Function knob on the TQi transmitter can be set 
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.

     Throttle Trim Seek Mode

When the Multi-Function knob is 
set to throttle trim, the transmitter 
remembers the throttle trim setting. If 
the throttle trim knob (Multi-Function 
knob) is moved from the original 
setting while the transmitter is off, 
or while the transmitter was used to 
control another model, the transmitter 
ignores the actual position of the trim 
knob. This prevents the model from 
accidentally running away. The LED on 
the face of the transmitter will rapidly 
blink green and the throttle trim knob 
(Multi-Function knob) will not adjust the 
trim until it is moved back to its original 
position saved in memory. To restore 
throttle trim control, simply turn the 
Multi-Function knob either direction 
until the LED stops blinking. 

     Fail-safe

Your Traxxas radio system is equipped 
with a built-in fail-safe function that 
returns the throttle to its last saved 
neutral position in the event of a signal 
loss. The LED on the transmitter and the 
receiver will rapidly flash red.

Restoring Factory Defaults

When programming your TQi transmitter, 
you may feel the need to start over with a 
clean slate. Follow these simple steps to 
restore the factory settings:
1. Turn the transmitter off.
2. Hold both MENU and SET.
3. Turn the transmitter on.
4. Release MENU and SET. The 

transmitter LED will blink red.

5. Press SET to clear settings. The 

LED will turn solid green and the 
transmitter is restored to default.
