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.
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 counter-clockwise reduces steering throw (
Note:
turning the dial counter-clockwise 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. Many
racers set Dual Rate so they have only as much steering throw as
they need for the track’s tightest turn, thus making the car easier to
drive throughout the rest of the course. Reducing steering throw
can also be useful in making a car easier to control on high-traction
surfaces, and limiting steering output for oval racing where large
amounts of steering travel are not required.
Throttle Sensitivity (Throttle Exponential)
The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity, 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 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 car) 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
the Steering Trim knob to zero before making final adjustment
(if required) using Sub-Trim. If Throttle Trim has been previously
adjusted, the Throttle Trim will need to be reprogrammed to “zero”
before making final adjustment using Sub-Trim.
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 full clockwise will deliver
maximum brake throw; turning the knob counter-clockwise reduces
brake throw (
Note : Turning the dial counter-clockwise 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 on
page 32 for more information.
Setting Lock
Once you’ve adjusted all of these settings the way you like them,
you may want to disable the Multi-Function knob so none of your
settings can be changed. This is especially handy if you operate
multiple vehicles with a single transmitter via Traxxas Link
