Note:
If you select any of the control functions 5 ... 16 for
fi xed-wing models or 5, 7 ... 16 for helicopter models,
do not forget to assign a transmitter control for each
of these in the »Control adjust« menu!
"S" as switch channel
Selecting "S" (switch channel) in the fr column has
the effect of passing a constant input signal to the
mixer input, e.g. in order to add a little more "up-
elevator" trim when the aero-tow release is closed, as
mentioned on the previous page.
After assigning a control function or the "S" switch
channel in the "fr" column, the following is also
displayed ...
" to "
... on the lower edge of the screen.
Use this column's input fi eld to specify the destination
of the mixer, i.e. assign mixer output, to one of the
control channels. At the same time, additional fi elds
will appear in the bottom line of the screen:

In this example, four mixers have already been

principle as "Elevat curve" from the "Brake settings"
sub-menu of the »Wing mixers« menu and the third
is familiar from the line "Tail" ("2ELSv3+8") of the
»Model type« menu. As a general rule, however, you
should fi rst make use of the pre-programmed mixers.
However, if you need asymmetric mixer ratios, want
to program non-linear curves or need to offset the
mixer neutral point, then you should set or leave the
pre-programmed mixers at "0 %" and replace these
with free mixers.
Erasing mixers
To erase a previously-defi ned mixer, select the
appropriate line with the  selection keys on the
left or right touch pad , switch to the "fr" column, if
necessary, with the  selection keys then briefl y

Mixer switches
In the sample screen image shown above, switches
"4" and "2" have been assigned to linear mixers 1 and
4 and to mixer 2 of the control switch "G4".
The switch symbol to the right of the switch number
shows the current switch state.
Any mixers not assigned to a switch, as indicated
by an empty cell for the column marked by the
switch icon
on the screen's bottom line, are
fundamentally active!
A switch must be assigned to LinearMIX 4 if you
wish to switch between two fi xed mixer values (still
to be set) that correspond to the two end-points of
a (proportional) transmitter control. Accordingly, the
"switch channel" mixer cannot also be switched "on"
or "off" as with the other mixers.
If you intend to assign a control switch (G1 ... G4)
as a switch, then please note that you must defi ne
this appropriately BEFOREHAND in the »Control
switch« menu. If you do not, you will assign an
undefi ned control switch and therefore one that
functions as a fi xed switch.
