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.

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. Many racers set Steering Percentage
so they have only as much steering throw as they need for the track’s
tightest turn, thus making the model easier to drive throughout the rest
of the course. 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 full 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 below 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.
