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 filled.
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 filled.
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, 2 FLAP in the Aircraft Type
screen, a mix to one aileron channel affects both aileron servos.

Sequencer

The Sequencer menu option provides this-then-that mixing
with a time delay. Five different sequences (S1 through S5)
are available to control 2 functions each (A and B), in 2 timing
directions (forward or reverse). Sequences appear throughout
function screens as assignable switches.
CAUTION: Always review the action of a sequence on
the Monitor or X-Plus Monitor screen BEFORE operating the
model to ensure controls act as desired. Failure to do so could
cause a crash, resulting in property damage and or injury.
You can program multiple functions to sequentially activate
in response to an assigned switch. For example, an assigned
Gear switch can open gear doors, lower the gear, then close
the doors. In reverse, gear doors open, the gear retracts
and the gear doors close.
You can assign each Sequencer function to a switch in most
Function screens such as Flight Mode, Dual Rate, Mixing,
Throttle Curve, Pitch Curve, etc.
You can assign several functions to a sequence to decrease
the number of controls you need to touch during complex flight
transitions—for example, applying your assigned dual rates
and exponential when the landing gear deploys and the
flight mode changes.

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.
1/2% Mixing values
When adjusting the mix values near center (below 10),
1/2% mix values are available for fine adjustment capability.
IMPORTANT: 1/2% mixing is only available in program mixes
and rudder to aileron/elevator in aircraft model type.
Origin Mixing
Origin Mixing uses true stick position as the input for a mix. When
origin mixing is selected, any other settings to the master channel
will be ignored and the mix will be based strictly on stick position
and trim position. When Aileron, Elevator, or Rudder are selected
as the master, origin mixing is available. Once Aileron, Elevator,
or Rudder are selected, an N will appear next to the master chan-
nel, where N means normal. Change the N to O for origin mixing.
Next, select the slave channel and set the switch and mix rates
as desired.
If you select an S-Number-A sequence (e.g. S3A), the sequence
operates as a timed 5-position switch. An S-Number-B sequence
operates as a timed 3-position switch. The 5 positions correspond
to the sequencer values shown on the time delay graph in the
second Sequencer screen. In a function screen, highlight each
point (0–4) and select the switch position desired for a function
to be active.
When S1B (or another sequence-number-B) is selected as a
switch in a function, the sequence will operate as a timed 3-posi-
tion switch. The 3 positions act as 'kick points' of the movement
at fixed percentages (equal thirds) of the sequencer output. In a
function screen, highlight each point (0–2) and select the switch
position desired for a function to be active.
Sequencer Set Up
1. In the first Sequencer screen, select 1 of the 5
available sequences.
2. In the second Sequencer screen, assign a switch to
the sequence. We recommend using a 2-position switch.
Tip: If you need to use a 3-position switch, you must assign
one direction to two adjacent switch positions, e.g., 0 and 1.
Assign the opposite direction to the third switch position.
