Mixing

(Function Mode)

–

The DX3.0 offers two different mixing adjustments that allow for mixing one channel to another

channel. The mixes available are Steering-to-Auxiliary Channel Mixing and Throttle-to-Auxiliary

Channel Mixing. Each direction is independently adjustable. Popular use of this function

includes 4-wheel steering and independent front and rear wheel brakes.

For example, Throttle-to-Auxiliary channel mixing can be used for independent front and rear

wheel brakes. Each time the throttle/brakes is moved, the auxiliary channel will move in the

direction and to the value input being given by the throttle channel. Mixing is proportional, so

small inputs to the throttle will result in small output from the auxiliary

channel. The adjustment range is from -125% to 0% to 125%. If the rate is negative, the

channel is mixed in the opposite direction.

Both mixes share a single mixing “offset.” The purpose of the mixing offset is to redefine the

neutral position of the auxiliary channel, which can be set using Grip Lever A when

“LN” is selected in the Auxiliary Channel 3 function. If the “LN” selection is turned off in the

Auxiliary Channel 3 function with an offset value currently present, the value will

continue to act as a mixing offset until the value is either cleared or changed. If a mix is not

required, it is strongly suggested the mixing rate be set for 0%, which is the default.

Accessing the Mixing Adjustment Function

1. Turn the transmitter power switch on.
2. Press the

SCROLL key to access Function mode.

3. Press the

SCROLL key until “MIX” appears in the screen.

4. Press the

CHANNEL key to select the desired mix to be used.

5. Move the steering wheel or trigger in the desired direction for adjustment (left/right,

forward/reverse or brake). Press the

INCREASE or DECREASE key to achieve the

desired amount of mixing. Move the wheel or trigger in the opposite direction to adjust

the mixing in the opposite direction.

Note: For Auxiliary Channel 3 function, if LN is selected, only L/F is adjustable.
6. Press the

SCROLL key to access the Lap Timer (if enabled) or Sub-Trim function.

7. To exit the Function mode, either turn the transmitter power switch off or press the

SCROLL and CHANNEL keys at the same time.
