On this page, use the arrow key

on the left or
right touch pad to select the line under "Offset" and
then tap the center
SET key on the right touch pad.
Depending on the travel adjustment selected on the
"Control adjust" menu and the switch position, the
offset value jumps to +X% or -X%, e. g.:
L.MIX 4

Now use the arrow

key on the left or right touch
pad to move to the line under "Mix input" and then
tap the center
SET key on the right touch pad. The
value fi elds are now highlighted. After you have
moved the selected switch to the mixer ON position,
use the arrow keys on the right touch pad to set the
required symmetrical mixer ratio.

If you have a multi- fl ap wing featuring a "crow or 2.
butterfl y system" with (additional) airbrakes, and you
wish to test the effect of this braking system with and
without airbrakes, then you should simply set channel
1 to "MIX-only" …

… and follow this by programming 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.
The fi nal example applies to model helicopters:
3.
In the helicopter program, if you wish to assign
collective pitch trim via one of the CTRL 6 … 8
proportional rotary controls, use the
"Control
adjust" menu to assign one of these transmitter
controls to (e.g.) "Input 9". (Leave the default value
of "GL" in the "Type" column alone, however, to
confi gure this setting globally for all fl ight phases
– as will be the case for the free mixer yet to be
programmed. Finally, you then simply defi ne a free
mixer "9

11" with a symmetrical mixer ratio of e. g.
25%. Due to the internal coupling, this transmitter
control then acts equally on all of the model's
collective pitch servos without affecting the throttle
servo.

Decouple the assigned transmitter control from
control channel 9 on the "
MIX-only channel " menu,
however, to ensure that any servo connected to
receiver output 9 can no longer be operated by this
transmitter control; see also page 193.
