Operation Manual

Caution
-
don't turn
the switches
themselves
round!
They
must be installed
as dictated
by the
Transmitter
Control
Test on
page
66;
otherwise
the whole arrange-
ment will be uoset.
The asterisk
(star)
which appears after
the arrow
in one
of the
two
oositions
shows that
the switch
is
"ON"
in
this Dosition.
This entire
"switch
corner" only
appears
on the screen
when
you
are dealing
with
an
option
which requires a
mechanical switch;
for
fixed-wing models
these are
"Dual
Flates" and
"Fixed
Value".
Dual Rates reduces
servo travel equally
in both direc-
tions,
and
is
controlled
by a
mechanical switch.
The
"Expo"
option
(exponential
travel)
An exponential
curve
is one
which increases dispropor
tionately the
further it
moves away from
zero. lts effect
on a control
function
is that the servo
makes small
movements
around centre,
but the turther
the stick
is
moved, the
more servo travel
increases.
At the stick's
end-point,
the servo
reaches its own normal end-point.
In
practice
the
result is that the
pilot
has very
fine
con-
trol of
the model
in normal flight, but still
has available
the
large control
surface
movements which are
occa-
sionally
required.
Selecting
and setting up
this option are carried
out ex-
actly as described
for Dual Rates above, so
we do
not
need to
repeat the
information in detail.
Exoonential
is not switchable; so
there is no
mechani-
cal switch
to
select.
00/o exoonential
means
normal, lin-
ear control
characteristics.
1000/0
is
the
maximum
possi-
ble
exDonential deviation
from normal.
Fig.21
The
"asymmetrical
travel adjustment"
option
This facility
allows
you
to adiust
maximum servo
travel
separately
for each of the
two directions of
the stick.
Fig.22
A typical
application
would be
in
a
model whose control
resDonse
is not equal in both directions,
perhaps
for
aerodynamic
reasons.
It is available
for
all control
functions
with the exception
of
"throttle"
and
"ailerons".
The first step
is to select
Control C
with the sequence
Z
and
ElE,
then
ASYM.
TRAVEL
with the key sequence
S,
followed by
El E.
This option
is located
in
the
"Transmitter
Control
Op-
tions"
menu, and
is found
by
"leafing
through":

The adjustment
process
itself :
Press
the
Z
key; the set
value on the
right starts to
flash. Move stick
C to its
right-hand end-point;
the
small arrow
betore the displayed
value will tace
right. lf
you
adjust the
travel with the
El
and
El
keys,
this setting
applies to
travel to the
right of centre.
Move
the
stick to the
left
end-point;
the small
arrow
will
point
to the
left. You can now set
travel to the
left
(again
using
the
El
and
E
keys). looo/o
=
maximum
possible
travel; 00/o
=
zero travel.
That was simple enough.
One
further
point
to note:
In the adjustment
process
just
described
it makes
no
difference
whether
the stick is at
full right or
full left
movement-
The crucial
point
is that the small arrow
points
in the correct direction.
All
you
need to do
is move the stick slightly
to the de-
sired
side; even
moving the üim slider
is enough. Just
watch the small arrow;
it indicates whether
you
are ad-
justing
the
right-hand or left-hand travel.
In the case
of
'torclall'
movements or switches small
up and down
arrows appear.
