ABS helps prevent brake lock-ups and improves braking perfor-
mance by pulsing the brakes.
The following ABS braking parameters can be programmed:
State: Inhibit or Active
Point: The throttle position that the pulse braking
takes place. (0 to 100, default is 60)
Stroke: The distance the throttle travels during the
pulse braking. (0 to 100, default is 50)
Lag: The time delay before the pulsing takes place
(0.0 to 2.0 in .01 increments, default is 0.5)
Speed: The pulsing speed or frequency of the pulse
braking. (-1 to -30, default is -1)
The graphic bar at the bottom of the screen displays the parameters
and shows how ABS will function.

Servo Speed
The Servo Speed function allows
you to change the speed of any of
the four channels—steering, throttle
and Aux. from 100% (default) to
1%. The maximum speed is 100%
and is fi xed by the specifi cations of
the servo itself.

tion. Press the roller to access the
Servo Speed function. The Servo
Speed screen appears.
• Use the roller to select the desired
channel, then press the roller to access that channel. Rotate the
roller to adjust the servo speed.
Trim Step
Trim Step affects the
amount the servo travels
with each click of the trim,
but has no effect on the
total trim travel. The trim
steps range from 1 to 20
(Default is 4). To adjust the
trim step:
1. Select Trim Step from
the List menu.

channel and press the
scroll wheel to activate the
channel.
3. Rotate the scroll wheel
to adjust the trim step.
4. Press the scroll wheel to save the selection.
Programmable Mix
The programmable mixes enable you to assign any
channel as a Master or Slave, which is particularly
helpful when you need to assign an Aux channel as
a Master.
1. Scroll to Inh. Press the rolling selector once
and select a Master channel.
2. Select a Slave channel.
3. Adjust the A Value percentage.
You can assign custom names to Mix A and Mix B,
making it easier to remember what each mix does.
Assign the names the same way you would for the
Username or Model Name.
Mix Options
Trim: Inh or Act. When Trim is Active, trim adjust-
ments to the Master channel also apply to the
Slave channel.
Switch: You may assign the mix to a switch,
enabling a B Value in the mix.
To adjust the B Value:
1. Assign a switch to the mix.
2. Press the switch forward or back. The A
Value changes to B Value on the screen.
3. Select the B Value and move the scroll
wheel to adjust the value.
4. Press the Rolling Selector to save the
selection.
NOTICE: Before driving a model, always
do a check of the model’s response
to mix settings. Raise the vehicle off
the ground so it does not move during
testing.
NOTICE: A negative value results in the
secondary channel moving in a direction op-
posite the direction of the primary channel.
