Depending on the mixer value configured, a mixer
can, as shown in the example above, route the signal
from a flap control present (e. g.) on input 6 to control
channel 11, while also applying the FLAP trim value
set on the »Phase trim« menu (page 150) for the
respective flight phase.
Other special features of free mixers
Mixer input = mixer output
If you set up a mixer whose input is the same as
its output, e. g. "C1 C1", you can achieve some
very special effects in conjunction with the option of
switching a free mixer on and off in any way you like.
A typical application of this can be found at the end of
this section, as Example 2 on page 218.
Tip:
If you separate a control function, e. g. "9", from
control channel 9" using the »MIX-only channel«
menu (see page 221), then servo response is
defined only by the mixer ratio (yet to be specified)
of the mixer programmed on the same channel.
Thus, with linear mixers LinearMIX 1 ... 8 or curve
mixers CurveMIX 9 ... 12, 8-point control curves can
be defined for any transmitter control in a manner
analogous to that described in the »Channel 1
curve« menu (pages 140 ... 143) and these can also
be used in flight phase switching if needed.

Mixer output affecting default software coupling
of aileron, camber-changing flap or collective
pitch servos
Before we start specifying the mixer ratio, we must
first give some thought to what happens if we permit
a mixer to affect the default software coupling of ai-
leron, camber-changing flap or collective pitch servos:
•
Fixed-wing models:
Depending on the number of wing servos available
on the "Aile/flaps" line of the »Model type« menu
(page 105), control channels 2 and 5 are connected
via special mixers for the "aileron" function, 6 and 7
for the "flap" function, outputs 9 and 10 (if present)
for the FLAP2 servos and 11 and 12 for AILE2
servos.
If mixer outputs are programmed to affect these
kinds of couplings, then their effect on the
respective flap pair derived from the "receiving"
control channel must be accounted for:
Mixer
N.N.* 2
N.N.* 5
N.N.* 6
N.N.* 7
* N.N. = Nomen Nominandum (the name to be stated)
Effect
servo pair 2 + 5 responds with an
aileron function
servo pair 2 + 5 responds with a
flap function
servo pair 6 + 7 responds with a
flap function
servo pair 6 + 7 responds with an
aileron function
N.N.* 9
servo pair 9 + 10 responds with a
flap function
N.N.* 10
servo pair 9 + 10 responds with an
aileron function
N.N.* 11
servo pair 11 + 12 responds with a
flap function
N.N.* 12
servo pair 11 + 12 responds with
an aileron function
•
Model helicopters:
With helicopter mixers, collective pitch control
may be provided by up to 4 servos connected
to receiver outputs 1, 2, 3 and 5, depending on
helicopter type. The software links these together
to control collective pitch, roll and pitch-axis.
Other than within the »Helicopter mixers«
menu, it is not advisable to mix a free mixer into
these channels because this can lead to very
complex interactions. One of the few exceptions is
"Collective pitch trim using a separate transmitter
control" – see example 3 on page 218.
Important notices:
•
With serial links in particular,
remember that the travels of the
individual mixers are cumulative if
multiple stick commands are made
simultaneously: there is a risk that the
servo(s) may strike a mechanical end-
stop. If necessary, reduce "servo travel"
to avoid this; alternatively, set "Travel
limit" on the "Servo adjustments" menu
and/or reduce mixer values.
• Take advantage of the ever-
present option to switch over to the
transmitter's »Servo display« menu
(see page 282). This menu is reached
from almost any menu with a brief,
simultaneous tap on the keys of the
