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.

The Servo Speed function allows you 
to change the speed of any of the four

total trim travel. The trim steps 
range from 1 to 20 (Default is 4).

and press the scroll wheel to 
activate the channel.

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.

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.

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.

secondary channel moving in a direction op-

posite the direction of the primary channel.
