Three turther tips on this subiect.
1. In the example above you could use the names
"CORT-T11" instead ol "CORTINAI', "CORT-NF2"
instead of "CORTINA2" and "CORT-HS3" instead of
"CORT|NA3". In this case TL stands for tow launch,
NF for normal flight, and HS for high speed. The
names will then remind you of which list serves which
purpose. The f inal numbers must remain; but they are
not very inlormative on their own.
2. lI you change memories in the "normal" way trom
the keypad, please check that the Memory Switch is in
the "basic" position. Otherwise the following will hap-
pen: you want to change to, say, Memory No. 13. Let's
suppose that it contains a model list which you have
set up as a "switchable" one. lf the Memory Switch is
in the wrong position, the transmitter immediately
changes to the new memory, and instead of No. 13 you
end uo at No. 14 or No. 15. This can lead to consider-
able confusion.
3. Please don't use this Jeature tor "simple" switching
tasks; it always "costs" you one or two memories. For
example, you could execute a simple change of cam-
berchanging f lap by switching memories; but it is just
as easy to use the "Fixed Value" from the Transmitter
Control options, and this alternative would not swallow
up another memory.
Servo assignment for wings
with more than two controlsurfaces.
On page 26 we discussed the "traditional" assigning
process for the aileron servos of models with wings fea-
turing separately controlled, electronically
differentiated
ailerons. The recommended
assignment is as follows:
Servo No. 1 = Aileron 1
Servo No. 5 = Aileron 2
For wings which have more than 2 control surfaces, all
of which act as (mixed) ailerons, and all of which are to
feature differential movements, this assignment can no
longer be used.
Exahple: "Quadro-flap" arrangement (see page 91).
In such cases the servos must be assigned
"in
sequential pairs".
An example will make this clear:
In the drawing we show an "extreme" wing layout, with
3 control surfaces per wing, all of which are to work as
ailerons, and all of which require diflerential movemenl.
We have already explained how you control the six ser-
vos (with the "QUADRO" mixer); we have also dis-
cussed selecting and adiusting the "Differential"
ootion. Now all that remains is the order of the six ser-
vos at the assignment stage.
In our example, assigning " in sequential pairs" works
out like this:
Servo No. 1 controls QUADRO I Outboard pair
Servo No. 2 controls QUADRO I of control surfaces
Servo No. 3 controls QUADRO I Centre pair
Servo No. 4 controls OUADRO J of control surfaces
Servo No. 5 controls QUADRO I Inboard pair
Servo No. 6 controls QUADRO I of control surfaces
This should make everything clear. lf you have only two
servos per wing panel, (normal Quadro arrangement),
simply stop at No. 4.
lf you do not keep to this sequence, differential aileron
movement will not be correct.

The "Sl" switch
We have already mentioned the "Sl" switch on page
36, in connection with the transmitter control options
" Fixed Value 1" and "Fixed Value 2". You may have
noticed already that "Sl" is offered in the menus when
assigning the switches 51 - 52.
What is "Sl"?
"Sl" is another "non-hardware" switch, (i.e. a software
switch), in this case coupled to the transmitter control
input "l". Firstly, "Sl" is a "three-position switch", i.e. it
has an "idle position" in the centre, and a
"working
position" at both end-Points.
lf, for example, you connect a slider control to
"1", and
if the slider is set to centre, then "Sl" is also at idle
(OFF). lf you move the slider to one end-point, then one
side of "Sl" switches on. lf the slider leaves the end-
point again, "Sl" switches off immediately. At the other
end-point of the slider the same applies; only in this
case the other "side" of "Sl" is switched on and off.
ln this case "Sl" has the same effect as if two end-
ooint switches were fitted to the slider. With a little
imagination you can use this feature for many interest-
ing functions.
The main application of "Sl" is rather simpler, how-
ever.
In this case a "real hardware" 3-stage switch is con-
nected to input "1"; for example Order No.7 5699
(short toggle) or Order No. 7 5700 (long toggle).
It this "hardware" switch (actually a transmitter control
in this application) is operated, then of course it oper-
ates the "software" switch "Sl" as well. The final
effect is a 3-position change-over switch, which can be
used with the switches 51 - 55; but which has 3 posF
tions; compare this with 51 - 55, which are only simple
change-over switches.
And that is exactly what we need to switch between 2
dif{erent " Fixed Values" !
