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 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.

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 and when driving at high
speed. The ranges are exaggerated for illustrative purposes.

Experiment! Try varying degrees of exponential. By default, the
model is set to 70% exponential. There's no wrong way to adjust
exponential. Any setting that makes you more comfortable with
your car's handling is the "right setting."
Throttle Sensitivity (Throttle Exponential)
The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity as
described above, but applies the effect to the throttle channel.
Only forward throttle is affected; brake/reverse travel remains linear
regardless of the Throttle Sensitivity setting.
Steering Percentage (Dual Rate)
The Multi-Function knob can be set to control the amount
(percentage) of servo travel applied to steering. Turning the Multi-
Function knob fully clockwise will deliver maximum steering throw;
turning the knob counterclockwise reduces steering throw (Note:
turning the dial counterclockwise to its stop will eliminate all servo
travel). Be aware that the steering End Point settings define the
servo's maximum steering throw. If you set Steering Percentage
to 100% (by turning the Multi-Function knob fully clockwise), the
servo will travel all the way to its selected end point, but not past it.
Reducing steering throw can also be useful in making a model easier
to control on high-traction surfaces, and limiting steering output for
oval racing where large amounts of steering travel are not required.
Braking Percentage
The Multi-Function knob may also be set to control the amount
of brake travel applied by the servo in a nitro-powered model.
Electric models do not have a servo-operated brake, but the
Braking Percentage function still operates the same way in electric
models. Turning the Multi-Function knob fully clockwise will deliver
maximum brake throw; turning the knob counterclockwise reduces
brake throw (Note: Turning the dial counterclockwise to its stop will
eliminate all brake action).
Throttle Trim
Setting the Multi-Function knob to serve as throttle trim will allow
you to adjust the throttle's neutral position to prevent unwanted
brake drag or throttle application when the transmitter trigger is at
neutral. Note: Your transmitter is equipped with a Throttle Trim Seek
mode to prevent accidental runaways. See the sidebar for more
information.
Steering and Throttle End Points
The TQi transmitter allows you to choose the limit of the servo's
travel range (or its "end point") independently for left and right
travel (on the steering channel) and throttle/brake travel (on the
throttle channel). This allows you to fine-tune the servo settings to
prevent binding caused by the servo moving steering or throttle
linkages (in the case of a nitro model) farther than their mechanical
limits. The end point adjustment settings you select will represent
what you wish to be the servo's maximum travel; the Steering
Percentage or Braking Percentage functions will not override the
End Point settings.
Steering and Throttle Sub-Trim
The Sub-Trim function is used to precisely set the neutral point of
the steering or throttle servo in the event that simply setting the
trim knob to "zero" does not completely center the servo. When
selected, Sub-Trim allows finer adjustment to the servo output
shaft's position for precise setting of the neutral point. Always set
