Dual ST (Dual Steering)

Trim:

 

Act (Default) or Inh.  We recommend activating the Trim, as it adjusts the trim for both the left and right steering servos. If you 

need to make small adjustments to the individual servos, you can do so in the Sub-Trim menu.

Switch: 

You may assign the Dual ST mix to a switch, enabling a B Value in the mix. Assigning the Dual ST mix to a switch is valuable 

when you want to assign dual steer values for different conditions. For example, you may use a smaller value when the vehicle is moving 

faster. When the vehicle is moving slowly, use the switch to select the larger value and increase steering ability. You can also set one of 

the mix values to 0% if you want to turn the mix off.

Brake Mix

Use the Brake Mix on large scale vehicles that require separate front and rear brake servos.  The 

mix value creates brake bias between the front and rear brakes. Assigning the Brake Mix to a switch 

enables you to adjust the mix value from any screen. 

1.  Select AX1 or AX2 as the Slave channel. If Aux 1 or Aux 2 is assigned to another mix, it will not be 

available as a Slave channel option. 

2.   Adjust  the Brake Mix Value to establish the brake bias between the front and rear brakes. 

Switch: 

You may assign the Brake Mix to a switch. Assigning the Brake Mix to a switch enables you to 
adjust the brake bias from any screen. 

Motor On Axle (MOA) Throttle Mix

The MOA Throttle Mix is used to adjust the throttle bias on rock crawlers using a “motor on axle” configuration. 

Mix options:

•  Rear Dig
•  Front Dig
•  4WD

1.   Select MOA from the Throttle Mix menu.
2.   Scroll to Inh. Press the scroll wheel, then scroll to activate the mix. Press the 

scroll wheel again to adjust the mix.

3.   

To inhibit an option

  Scroll to the MOA option, then select Inh. All MOA options are active by 

default. If you inhibit an option, the Mix switch ignores the option.

4.   

Adjust the Throttle Bias Value (4WD Only)

  The value shown on the screen is a percentage of the rear motor rate. 
  For example, a value of “70%” means the rear motor power is 70% of the 

front motor power.

5.   

In Motion Adjustment

  You can assign the throttle bias to the following switches:

Assigning the Throttle Bias to a switch enables you to adjust the throttle bias 
while the vehicle is moving.

6.   

Assigning the Mix Options to a Switch

  Assign the MOA Options to a switch. Each time you move the Mix switch, the 

MOA options appear on the Main Screen.

Bias Step: 

The Bias Step affects the amount the mix changes with each click of the button or  
dial but has no effect on the total mix range.
