• The C1 stick still only operates the servo connec-
ted to receiver output 1.
Caution:
Check the screen carefully! When the ailerons are
operated, the bars in the »Servo display« should
move in the same direction; when fl aps are opera-
ted, in opposite directions.
The fi nal step in this procedure is to select the menu

… and carry out any fi ne-tuning of the servo travels
required.
This completes the basic programming of the eight-
fl ap wing.
Flap positioning in different fl ight phases
The fl ap positions can now be programmed to diffe-
rent settings for each fl ight phase. Start by program-
ming two or more fl ight phases using the menus
»
Phase settings « and » Phase assignment «. Take
this opportunity to change the standard “global” set-
ting for the effect of the digital trims to “phase”, if this
is what you want to achieve; this is selected in the
»
Stick mode « menu (see page 76).
An example of programming fl ight phases can be
found on page 174.
When you have completed this stage, move to the

Mix input
Why?
As already mentioned several times at relevant
points, inputs 5 … 8 can (and must) be programmed
separately for each fl ight phase in the »
Control ad-
just « menu. It has also been explained at the ap-
propriate point that “Input 7” is automatically de-cou-
pled from “Servo 7” if you choose “2 AIL 2/4 FL” in
the “Ailerons / camber fl aps” line of the »
Model type «
menu, i. e. it is virtually set to “Mix only” status by de-
fault. However, we need just such a fl ight phase spe-
cifi c “free” input in order to be able to trim the inboard
fl aps separately for each fl ight phase. The “7
11”
mixer you have just set up simply links this to “Input 7”
in the background.
One fl ap setting for each fl ight phase
If you are satisfi ed with one fl ap position per fl ight
phase, then you need to move to the “
Multi-fl ap
menu ” of the menu …

… and set up the servo pairs “AILE” (2 + 5), “FLAP”
(6 + 7) and “FL2” (9 + 10) in each of the programmed

vious column.)
At this point in the proceedings you should also check
that inputs 5, 6 and 8 are set to “free” in each fl ight
phase. This ensures that any (accidental) settings of
transmitter controls or switches which you have mis-
takenly or accidentally assigned have no effect on the
model.
Note:
The offset you enter may need to be positive or nega-
tive, depending on the orientation of the servos in the
model’s wings.
