Exponential rate on the throttle stick
desen-
sitizes the
stick
at low
throttle
so
stick movement
versus RPM response can be more of a one-to-
one
relationship because most carburetors have
non-linear
response.
The amount
of
oqponential
rate
is
deter-
mined for each channel in the CAlibrate
mode.
It
can be set
from "O"
(which is
ofO
to
"9'
(whtch
is the most available). On the three neutralizing
channels, the Dual Rate switches serve double
duty and will
engage
or
disengage o<ponenttal
rate.
When the dual rate switch
is
in
ttre up
position, ttre orponential rate curve you
have
chosen
is
turned
on.
T?re
endpoints of
servo
travelwill
remaln the
same as
theynormally
are
for
this
switch position.
If exponential rate is enabled for
throttle, lt is
always
on.
C.
Mixing
1.
Universal Mixing
The
micropro
offers totally universal
mldng.
You
will
ffnd when you get to Midng
in
the
calibration section of the
iestructions, you
can
program limifless
midng
capabtlities
for
any
imaginable requirement.
Up to twelve
mldng
tasks can
be
assigned to
mi:dng switches in order
to have the
capabilityof
turnlng the mixing tasks on or off.
Essentially,
there are three
mldng switches. "Mix
I'
and
*J&fixz"
switches are accessible in normal opera-
tion and can
be turned on and off as desired.
"Mix
3'
is
always
ON.
You
will
assign
mfdng
tasks to *Mlx 3" that you never want to
turn off
when you
are
flying.
Up to four mldng tasks
can
be assigned
to
each of the three switches for
a
total
of twelve.
(Note: tf you want to be able to turn'Mix
3"
on or off,
it
can be done
by installing
another
switch in the
transmitter.
Contact the factory
for
details.)
The LCD Display
wtll indicate the status of
ttre mixing
switches. If an "M'
appears
in
the
"Mix 1", "Mix 2", or
"Mix 3"
locatlons, that
particular switch ls
on.
You
wlll
note that
the
'M'
is
always displayed
for "Mix
3',
indicating
that
it
is always on.
2.
Pre-Programmed Mixing
As a short cut, there are ttrree mfidng func-
Uons
that
are
pre-programmed
in
your micropro
that you
can access.
All
of these are always on
and not affected by the mixing switches.
Aileron
Differential:
Thls feature allows you
to control the amount
of
up versus down travel
on
each
individual aileron
in
order to do away
with the
adverse
yaw
caused
by the
ailerons
moving downward, particularly
in
$iders
and
high winged powered planes.
V-Tail: This feature
mixes elevator
into rud-
der and ru dder back into
elevator for
a
a/-Tailed"
airplane appltcation.
Elevon: The best orample
of
Elwon
mi:dng is
a delta
winged airplane
tllat
uses the two
control
surf,aces
at the rear or the wing for both pitch
(elevator)
and
roll
(ailerons).
D.
AutoTrim
AutoTrim allows you to
trim
ttre aircraft by
only using
a
push button switch
and not removing
your hands from the sticks. AutoTflm
is
activated
by pushing theAUTO TRIM switch which moves
the
servos
in
the same direction
in
which
the
sticks are displaced from
neutral. This movement
of
the servos
will
be at a slow and controlled rate
(this is called slewtng)
so there
will
be
no quick
movement of the
aircraft. AII
three
neutralizing
channels (Elerzator/Aileron/Rudder) are effected
by
AutoTrim if their stick is
displaced.
For gross trimming
on the
inittal fltght
of a
new, out-of-trim model, displace tJe
sticks
as
necessary
to fly the
model 'straigf,rt and level'
and press the
auto-trim swltch.
.ds
you
continue
to fly
the airplane straight and
level
with
the
auto-trlm button pushed, you
will
notice ttrat
eventually,
the sticks
will
be
in
ttre
neutral
position
as the airplane flys tn the
desired
atti-
tude.
After the plane is
rougfily trimmed by this
method, the best way to "fine tune"
the
AutoTftm
is to start with the control in neutral, push tlre
ALIO
TRIM switch, and then *bump" ttre
re-
spective control a few times
ln
the direction you
want to
move the servo to get
it
ireto
a trimmed
position.
Youwillbesurprisedathowquickly
this
unique method of trimming
will
become
second
nature
to you while flying.
The amount
of
offset
from neutral
the
AutoTrim feature has created can
be read and
ttren incorporated as a new neutral, or you can
mechanically
trim
the airplane with tts linkage
and
return to the transmltter's normal neutral
by zeroing
out
the
AutoTfim.
We
wtll
explatn
either procedure in the CAlibrate
secflon of the
manual.
The speed at
which the
servos "slew" can be
controlled. Also,
if
d
esired,
the
AutoTf im feature
can be
turned off.

the
AutoTfim
