Mixing
Mixing allows control input for a channel to affect more than one
channel at a time. Mixing functions support:
• Mixing a channel to another channel.
• Mixing a channel to itself.
• Assigning offset to a channel
• Linking primary to secondary trim.
These mixes are available for each model memory:
16 programmable mixes
Select a channel for master and slave. Inputs for the mas-
ter channel control both the master and slave channels. For
example Elevator to Flap makes elevator the master channel and
fl ap the slave channel.
Offset
Change the offset value to move the effective center position
of the slave channel. Positive or negative value determines the
direction of the offset. Offset is not available for curve mixes.
Trim
If the master channel trim should also adjust the slave channel,
set Trim to Act. A channel monitor on the left side of the screen
shows how channels respond to input. To view a switch-as-
signed mix on the monitor, the mix switch must be in the active
position.
Assigning a Mix to a Switch
If you wish to assign a mix to a switch position:
1. Scroll to Switch and press the scroll wheel.
2. Scroll left or right to the switch you wish to use and press
the scroll wheel to save the selection.
3. Scroll to the switch position where you want the mix to be
active.
The mix is Active when the box is fi lled and Inactive when the
box is open. You can assign a mix to be active in multiple switch
positions (0,1 or 2).
CAUTION: Always do a Control Test of your model
after changing mixes.
Combo Mixing
Combination Mixing is available to create OR mixing where you
can assign 2 conditions and the mix activates if either condition
occurs. You can also create AND mixing where 2 conditions
must occur to activate the mix.
To program Combination Mixing:
1. Activate a mix.
2. Select Combo Sw. in the Switch Selection. The Combo
screen appears.
3. Select the desired switch and active switch position for
Switch 1.The mix is Active when the switch position box is
fi lled.
4. Select the Relation (AND, OR)
5. Select the desired switch and active switch position for
Switch 2.The mix is Active when the switch position box is
fi lled.
6. Press the BACK button to save the Combination Mix.
The Master (left side) names are inputs. For example, “Aileron”
refers to the Aileron Stick. The Slave (right side) name is the
name of the channel receiving the mix command when the
Master channel moves.
Back Mixing
Back Mixing applies a mix to all related servos in a wing or tail
type. For example, if you select 2 AIL, 2FLAP in the Aircraft Type
screen, a mix to one aileron channel affects both aileron servos.
The mix response, however, depends on the aileron channel
included in the mix.
A Back Mix also enables you to use fewer mixes to achieve the
desired response, for example adding roll to a split elevator.
