ABS helps prevent brake lock-ups and improves braking
performance 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.
IMPORTANT:
State must be Active to
turn on the ABS function.
• In the List screen, use the roller to

that 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 fixed by the specifications
of the servo itself.

highlight the Servo Speed function.
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.
2. Scroll to the desired 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.
IMPORTANT:
A negative value results in the
secondary channel moving in a direction op-
posite the direction of the primary channel.
