For each model memory (1 to 30) four linear mixers
are available, and two curve mixers with the additio-
nal feature of non-linear characteristic curves.
The menu »MIX active/phase« (page 108) enables
you to activate particular mixers separately for spe-
cifi c fl ight phase. In the interests of clarity the blo-
cked mixers are then suppressed in the appropri-
ate fl ight phase of the »Free mixers« menu.
In the default state of the mc-22s transmitter this me-
nus are initially suppressed. To activate it, move to the
»Suppress codes« menu (see page 49), or set this
menu point to “yes” in the »Basic settings« menu
(see page 117) before you set up a new model me-
mory.
In the following fi rst section we will concentrate on the
programming procedure for the screen page shown
at the top of this column. We will then move on to the
method of programming mixer ratios, both for linear
mixers and also curve mixers, as found on the second
screen page of this menu.
Basic programming procedure:
1. Select mixer 1 ... 6 with the rotary control pressed
in.
2. Defi ne the mixer input “from” and the mixer output
“to”.
3. If required, enter a serial mixer link (“Type” co-
lumn).
4. Optionally: include the trim levers for the mixer in-
put signal (“Type” column).
5. Assign a mixer switch if required.
6. Defi ne the mixer ratios on the second screen
page.
7. Switch back to the fi rst page by pressing ESC.
“from …” column
After a brief press on the rotary control, use the rota-
ry control to enter the mixer input in the selected mi-
xer line in the inverse video fi eld of the “from” column.
This must be one of the control functions 1 ... 12 or S.
In the interests of clarity the control functions 1 ... 4
are abbreviated as follows in the Fixed-wing program:
C1 Throttle / airbrake stick
AI Aileron stick
EL Elevator stick
RU Rudder stick
And in the Heli program:
1 Throttle / collective pitch stick
2 Roll stick
3 Pitch-axis stick
4 Tail rotor stick
Note:
Don’t forget to assign a transmitter control to the se-
lected control function 5... 12 in the »Control adjust«
menu.
Switch channel “S”
The letter “S” (switch channel) in the “from” column
has the effect of passing a constant input signal to the
mixer input, e.g. in order to apply a little extra up-ele-
vator trim when the aero-tow coupling is closed, as al-
ready mentioned.
After assigning a control function or the letter “S”,
move on to the …
“… to” column
… where an additional SEL fi eld now appears. At this
point you can defi ne the destination of the mixer, i.e.
the mixer output, as one of the control channels. At
the same time additional fi elds will also appear in the
bottom line of the screen.
Example:
In this example four mixers have already been defi -
ned. The second mixer (“Brake 3 elevator”) is al-
ready familiar to us from the »Wing mixers« menu.
As a general rule you should always use these pre-
programmed mixers fi rst if possible. Admittedly, if you
need asymmetrical mixer ratios on both sides of cen-
tre, or wish to program a non-linear curve, or need to
offset the mixer neutral point, then you should pro-
gram one of the free mixers instead of the pre-pro-
grammed alternative.
Erasing mixers
If you need to erase a mixer that you have already
defi ned, simply press the CLEAR button in the inver-
se video fi eld of the “from” column.
Mixer switches
In the example shown above, the external switches
and control switches “6”, “G4” and “7” have been assi-
gned to the three linear mixers 1, 2 and 4.
The switch symbol shows the current state of the
switch. The extreme right-hand column shows whe-
ther the mixer in question is currently switched “off”
