On this menu, you can interrupt the normal signal fl ow
between the
control function on the input side and the
control channel on the output side: the "traditional"
transmitter control/servo connection no longer applies.
One particular use of the options offered by this
fl ight
phase-independent menu might to reliably keep one of
the control channels "free" in all fl ight phases, as these
control channels can be assigned a transmitter control
or switch for specifi c fl ight phases on the " Control
adjust " menu.
Conversely, a joystick, transmitter control (CTRL 6 …
10) or switch (SW 1 … 3, 8 and 9) "robbed" of its servo
in this way can of course be used anywhere else as a
transmitter control – even in a fl ight phase-specifi c way.
See the programming examples to the right and on
pages 255 and 266.
A joystick, transmitter control (CTRL 6 … 10) or switch
(SW 1 … 3, 8 and 9) robbed of its servo by setting the
channel to "MIX only" will then namely affect mixer
inputs only …
… and the servo connected to a channel set to "MIX
only" is then also only accessible from the mixers
programmed to its control channel, i.e. "(with) MIX(ers)
only".
Accordingly, for any channel set to "MIX only", you can
utilize both its control function and its control channel
entirely independently of one another for any special
functions you need; see the examples at the end of this
section.
Use the arrow keys on the left or right touch pad to
select the desired channel from 1 to 12 (

) and then
briefl y tap the center SET key on the right touch pad,
so as to switch as you please between "normal" ( ) and
"only" mode ( ):

Examples:
For model glider aircraft without airbrakes, the •
butterfl y function (page 160) is generally used as
a landing aid. Just as with "normal" airbrakes, this
is generally controlled using the C1 stick. While the
(airbrakes) servo typically connected to channel 1 is
then generally absent as a rule, receiver output 1 is
still not "free", since the control signal of the brake
stick is still present at this location.
Its control signal – – which in this example is not
required – can be decoupled from control channel
"1", and thus "free up" this channel from the C1 stick
signal, by setting channel 1 to "MIX only" on the
"
MIX-only channel " menu. This makes it possible
to use control channel "1", together with receiver
connection "1", at any time for other purposes, via
freely-programmable mixers – e. g. to connect up a
speed controller.
If your model has built-in airbrakes, however, and
•
you would like to perhaps test the performance of a
butterfl y system with and without airbrakes, simply
set channel 1 to "MIX only" and program a free mixer
"C1

C1", so as to restore your ability to control the
airbrakes via servo 1. If you also assign a switch to
this mixer, then you will be able to switch this mixer
on and off as you please.
