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:
Select a channel for master and slave. Inputs for the master
channel control both the master and slave channels. For example,
Elevator to Flap makes elevator the master channel and flap the
slave channel.
• 10 programmable mixes
• Cyclic to Throttle (HELI)
• Swashplate (HELI)
• Elevator to Flap (ACRO)
• Aileron to Rudder (ACRO) • Rudder to Aileron/Elevator (ACRO).
• Aileron>Rudder (SAIL)
• Aileron>Flap (SAIL)
• Elevator>Flap (SAIL)
• Flap>Elevator (SAIL)
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-assigned
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. Make sure you are in the desired mix screen.
2. Move the switch you want to assign the mix to.
3. Scroll to the switch position where you want the mix to be
active.
4. Press the scroll wheel to activate the mix. When the box is
filled, the mix is active.
The mix is Active when the box is filled and Inactive when the
box is open. You can assign a mix to be active in multiple switch
positions (0,1 or 2).
Tip: Use Auto Switch Select to select the switch.
CAUTION: Always do a Control Test of your model after
changing mixes.
Back Mixing
Back Mixing applies a mix to all related servos in a wing or tail
type. For example, if you select 2 AIL, 2 FLAP 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.
