Linear mixers
For each model memory (1 to 12) three linear mixers
are available, with the additional possibility of non-linear
characteristic curves.
In this fi rst section we will concentrate on the program-
ming procedure for the fi rst screen page. We will then
move on to the method of programming mixer ratios, as
found on the second screen page of this menu.
Basic programming procedure
1. Hold the SELECT button pressed in, and select mi-
xer 1 ... 3 using the right-hand rocker button.
2. Press SELECT. The input fi eld "from" is highlighted
(inverse video).
3. Defi ne the mixer input "from" using the right-hand ro-
cker button.
4. Press SELECT, move to SEL under the "to" column
using the right-hand rocker button, and press SE-
LECT once more.
The input fi eld „to" is shown inverse.
5. Defi ne the mixer input "to" using the right-hand rocker
button.
6. Optionally: press SELECT, move to SEL under the
"type" column using the right-hand rocker button; you
can now include the Ch1 ... Ch 4 trim lever for the
mixer input signal ("Tr" for trim).
...and/or switch to the switch symbol; press SELECT
again and select a switch if necessary.
7. Press SELECT, move to using the right-hand
rocker button, and press SELECT or ENTER.
8. Defi ne the mixer ratios on the second screen page.
9. Press ESC to switch back to the fi rst page.
"from" column
Press the SELECT button, then use the right-hand ro-
cker button to select one of the control functions 1 ... 8
or S in the highlighted fi eld of the selected mixer line.
In the interests of clarity, the control functions 1 ... 4 are
abbreviated as follows when dealing with the Wing mi-
xers:
c1 Throttle / airbrake stick
ar Aileron stick
el Elevator stick
rd Rudder stick
... and in the Heli program:
1 Throttle / collective pitch stick
2 Roll stick
3 Nick stick
4 Tail rotor stick
Note:
Don't forget to assign a transmitter control to the se-
lected control function 5 ... 8 in the »Control settings«
menu.
"S" for switch channel
The letter "S" (switch channel) in the "from" column has
the effect of passing a constant input signal to the mi-
xer input, e.g. in order to apply a little extra up-eleva-
tor trim when an aero-tow coupling is closed, as menti-
oned earlier.
Once you have assigned a control function or the letter
"S", an additional SEL fi eld appears in the ...
"to" column
At this point you can defi ne the control channel as the
mixer destination, i.e. the mixer output. At the same time
additional fi elds appear in the bottom line of the screen:
In this example three mixers have already been defi ned.
The second mixer ("Brake elevator") is already fami-
liar to us from the »Wing mixers« menu. As a general
rule you should always use these pre-programmed mi-
xers fi rst if possible.
However, if you need asymmetrical mixer ratios on both
sides of centre, or wish to program a non-linear curve,
or have to offset the mixer neutral point, then you should
set or leave the pre-set mixers at "0", and program one
of the free mixers instead.
Erasing mixers
If you need to erase a mixer that you have already defi -
ned, simply press the CLEAR button in the highlighted
fi eld of the "from" column.
Mixer switches
In our example above, a physical switch "1" and the con-
trol switch "G1" have been assigned to the two linear mi-
xers 1 and 2, and switch 3 to mixer 3.
The switch symbol to the right of the switch number
shows the current status of that switch.
Any mixer to which no switch has been assigned in
the column is permanently switched on.
