Program description - Dual mixers
The differentiation, according to dual mixer configu-
ration, is only effective for rudder activation. In this
case, both corresponding trim wheels are effective.
No additional free mixers are required for this ar-
rangement.
When using this mixer, however, the tail type
MUST be entered as "normal" on the "Model
type" menu.
Tip:
All settings can be checked directly in the
»Servo display« menu, which can be
accessed from almost any other menu by
simultaneously tapping the keys on the left touch
pad.
Example:
Model with two rudders, with differential travel and
outward movement (e. g. swept-back ying wing):

When a rudder command is given, the second servo
connected to output 8 follows suit. (With this type of
programming, differential travel can be congured
for the rudders.) In this case, too, trim from the
rudder stick affects both servos. If the rudders are
also required to deect outwards when the airbrakes
are activated, then you should assign the C1 stick
(transmitter control 1) to input 8 on the »Control
adjust«" menu. Afterwards, change to the "Offset"
column then modify the offset value until both
rudders are again in their neutral positions. It may
be necessary to "play" a bit with the offset and travel
adjustments.
Note:
If “1 servo” is selected on the “Swashplate”
line of the »Helicopter type«“ menu, this
option is not shown on the multi-function
menu.
Use the selection keys of the left or right four-way but-
ton to scroll to the »Swashplate mixer« menu option
in the Multi-function menu:

Open this menu option with a tap on the centre SET
key of the right touch pad:

Note:
If "1 servo" is selected on the "Swashplate" line of the
»Helicopter type«" menu, this option is not shown
on the multi-function menu.
The number of servos installed in your helicopter for
pitch control was established in the Swashplate line
of the »Helicopter type« menu, see page 108. This
information is used to automatically couple together
the functions for roll, pitch-axis and collective pitch,
so that you do not need to define any other mixers
yourself.
Swashplate mixer
Collective pitch, roll, pitch-axis mixer
For helicopter models with only a single collective
pitch servo, this »Swashplate mixer« menu option is
of course superfluous because the software controls
a total of three swashplate servos for pitch, nick and
roll independently of one another, i. e. without a mixer.
In this scenario, this menu option is therefore no
longer available to you from the multi-function menu.
With all other swashplate linkages employing 2 … 4
pitch servos, mixer ratios and mixer directions are set
up by default as shown above. The default is +61 % in
each case but the value can be varied from -100 % to
+100 % if required by briefly tapping the centre SET
key of the right touch pad and its selection keys.
Simultaneously tapping both or selection
keys on the right touch pad (CLEAR) will reset the
mixer ration in inverse video again to the +61 % de-
fault value.
If the swashplate control system (collective pitch, roll
and pitch-axis) does not respond to the sticks prop-
erly, you should alter the mixer directions
("+" or "-") before trying to correct the directions
of servo rotation.
Note:
Ensure that changed mixer values do not
result in the servos mechanically striking their
end-stops.
