Asymmetrical mixer ratios
For many applications it is necessary to set up different
mixer values on either side of the mixer neutral point.
Start by resetting the offset of the mixer used in our
example (“6
¼
el”) to 0%, as shown in the picture
above. Now use the arrow button
f
of the left or right-
hand touch-key to select the ASY fi eld, and then touch
the central SET button of the right-hand touch-key. If
you now turn the rotary proportional control CTRL 7 -
assigned in our example to input 6 - in the appropriate
direction, the mixer ratio for each direction of control can
be set separately, i. e. to left and right of the selected
offset point using the arrow buttons of the right-hand
touch-key:
MIX1 6 el
tr v +20%
0% offs
SYM ASY
+55%
Note:
If you are setting up a switch channel mixer of the “S
¼
NN *” type, you must operate the assigned switch to
achieve this effect. The vertical line then jumps between
the left and right sides.
Examples:
The switch SW3 has already been assigned to con- 1.
trol channel 8 in the “ Transmitter control settings ”
menu, in order to open and close the aero-tow re-
lease.

In the meantime you have carried out a few aero-tow
fl ights, which showed that you always needed to hold
in slight up-elevator during the tow. You now wish to
set the elevator servo (connected to receiver output
3) to slight “up” trim when the tow release is closed.
In the screen display familiar from page 107 we have
set up the third linear mixer to accomplish this, using
the switch channel “S” as the mixer input. Now move
the selected switch to the OFF position, and move to

Use the arrow button

of the left or right-hand
touch-key to select the “Offs” line, then touch the cen-
tral SET button of the right-hand touch-key.
According to the travel setting selected in the “ Trans-
mitter control settings ” menu and the switch posi-
tion, the offset value now jumps to +X% or -X%, e. g.:

moving the selected switch to the mixer ON position,
set the required mixer ratio in the now highlighted

The following example applies to model helicopters: 2.
In the Helicopter program you may wish to assign
one of the rotary proportional controls (CTRL 6 … 8)
to the collective pitch trim function. This is the pro-
cedure: in the “
Transmitter control settings ” menu
assign one of these two transmitter controls to input
“E8”. Now simply defi ne a free mixer “8
¼
1” with a
symmetrical mixer ratio of, say, 25%. Due to the inter-
nal coupling, this transmitter control now acts equally
