The EPA function is used to set (or limit) the travel of each
servo,
and may be set anywhere from 0% and 125% for each
travel
direction. Reducing the percentage settings reduces the
total
servo throw in that direction. The EPA function is normally
used
to prevent any servos from binding at the ends of their
travel.
If you change the EPA setting to 0%, you will not
have any servo response in that direction, and will
probably crash.
4. To set EPA travel for other channels, press the Cursor Right
key to select the channel you wish to change. The little
triangle
moves and indicates the active channel. Repeat
these
steps with each channel in sequence, taking care to
set the travel for both directions. You may set each channel
separately,
anywhere in between 0% and 125%, and if you
wish
to rapidly return to the default 100% setting, press the
Active/Inhibit (Clear) key.
5. Return to the regular operating mode by pressing the two
Edit Up Down keys simultaneously.
Setting EPA values on your system:
1. Enter the programming mode by pressing the two Edit Up
Down keys (the two keys on the far left) at the same time.
You
should pop right into the EPA screen, but if you do not,
press
either Edit Up Down key until you see EPA displayed.
The
channel indicator is above numeral 1 for ailerons, the
percent
symbol will be flashing, and you'll notice that you
can change the L/U indicator to R/D (or vice versa) by
moving
the aileron (right) stick. In the next steps you will
see
how you set the travel directions independently for each
stick
(or lever or gear switch) motion.

Rates
If this is your first computer radio, you may have never been
introduced
to dual rates before. Dual rates are used because
most
models respond more rapidly to control inputs while
they're
flying at higher speeds, and it is possible to be really
gentle
with the controls and yet still over-control. Dual rates are
used
to adjust the transmitter so that a control actuated at high
speed
will not cause a radical response, so they are very useful
for
beginning pilots as well as experts.
Dual rates are selected by flipping the dual rate switches on the
transmitter.
The Optic has two dual rate switches, one for
ailerons
and one for elevator, and rudder. The aileron dual rate
switch
is located over the right-hand stick; the elevator and
rudder
dual rate switch is located over the left-hand stick. The
amount
of travel reduction or increase may be set anywhere
between
0 and 125%.
Note: if you set the dual rate amount to zero, you will get no response
from that channel, which may cause a crash.
2. To set the RIGHT aileron servo travel, move the aileron stick
all
the way to the right and hold it. The letters " R/D " should
appear
next to the flashing percent sign, meaning you are
setting
either Right or Up travel (with ailerons it's right or left
only,
but the display is set up to use the same indicators for
elevator
and throttle, thus the dual meanings for the letters).
Now
if your servo is stalled or binding, you'll hear a buzzing
sound.
Hit the Data -Decrease key until the buzzing stops.
If
the servo is not buzzing, leave the setting at 100%. Later,
depending
on how rapidly the model rolls, you can use
aileron
dual rates to reduce the sensitivity.
3. To set the LEFT aileron motion, move the aileron stick all the
way
to the left and hold it. The letters " L/U " should appear
next
to the flashing percent sign. Again listen and hit the
Data -Decrease key until the buzzing stops. If the servo is
not
buzzing, leave the setting at 100%.
Inputting Dual Rate
V
alues
1. Get to the D/R screen with the Edit Up Down keys.
2. The active channel number is indicated by the arrow above
or
below the channel numbers. The arrow's position
depends
on the position of that channel's dual rate switch.
In
the figure, the aileron (CH1) dual rate setting at the D/R
switch's
lower position is being programmed.
