Setting Up The Throttle Curve
1. Press one of the Up Down Edit buttons until the THCV
window appears. The default is for a linear curve, a straight
line from 0 to 100% passing through 50% at hover (center,
point 3).
2. Be sure you're in the desired flight Mode by moving the
Flt. Mode (SW-4) switch to its proper position. Remember,
you can input separate, independent throttle curve settings
for each separate idle-up mode (except for ST3, throttle
hold)! Also, be sure to center the hovering throttle lever
3. You begin at set point #1, idle. A small arrow should appear
over the number 1 in the display, and a value of 0% should
be shown. Press the Data +Increase or -Decrease key to
change the setting to your desired value. Inputting The Pitch Curve Values
1. Press one of the Up Down Edit buttons until the PTCV
window appears. The default is for a linear curve, a straight
line from 0 to 100% passing through 50% at hover (center).
2. Be sure you're in the desired flight Modes by moving the
Flt. Mode switch (SW-4) to its proper position. Remember,
you can input separate, independent throttle curve settings
for each separate idle-up mode.
3. You begin at set point #1, idle. A small arrow should appear
over the number 1 in the display, and a value of 0% should
be shown. Press the Data +Increase or -Decrease key to
change the setting to your desired value.
Choosing The On-Off Switch For Certain Radio Functions
1. Call up the Switch Select screen by repeatedly pressing one
of the Edit Up Down keys until the highlighted words S/W
SEL appear. The window may appear with any of the
following displayed: AIL D/R, ELEV D/R, RUDD D/R, R->T,
HOLD, PMX1, and PMX2. Note that if you change switch
locations, the switch labeled (for example) AIL D/R or SW-4
will not control aileron dual rate afterwards. You should
carefully consider how you assign all the switches in
consideration of the flight mode switches. See also Item 3a
below.
2. Use the Data +Increase or -Decrease keys to select the
desired function.
3. Use the Left Right Cursor keys to select from the following
on-off possibilities for the selected function
a. On indicates the function is ALWAYS on. You can also,
for example, set HOLD to be On at all times. This will
permanently disable the throttle servo, not a good thing!
Be very careful choosing ON as a possible setting for all
of these functions.
b. 1 represents Switch SW-1, the "ELEV RUDD D/R" switch.
On is down.
c. 2 represents Switch SW-2, the "GEAR AUX" switch.
On is down.
d. 3 represents Switch SW-3, the "AIL D/R" switch.
On is down.
e. 4 represents Switch SW-4, the "FLT MODE" switch.
The FLT MODE switch has three positions to select from:
i. NOR = on at forward position
ii. ST1 = on at middle position
iii. ST2 = on at aft position
4. Repeat Steps 2-3 for any additional functions you wish to set
4. When you're finished with Point 1, move to the next point
with the Cursor Right key. A small arrow over the number
2 indicates you are setting the value for Point 2. Note that
the function is inhibited (Inh) to start with. If you leave it, you
get a straight line from points 1 to 3. Otherwise, you can
change this setting with the Data +Increase or -Decrease
keys.
5. Repeat this procedure for Points 3, 4, and 5 by pressing the
Cursor Right key, then adjusting as desired with the Data
+Increase or -Decrease keys.
6. When you've completed the settings for the first flight mode
(NOR), test fly your model. When you're satisfied with the
settings, use them as a basis for the other flight Modes.
Flip the switches as necessary to get into the new mode,
verify on the display that you are in the desired flight mode,
then set all the five points in by going through the steps
given previously.
4. When you're finished with Point 1, move to the next point
with the Cursor Right key. A small arrow over the number
2 indicates you are setting the value for Point 2. Note that
the function is inhibited (Inh) to start with. If you leave it, you
get a straight line from points 1 to 3. Otherwise, you can
change this setting with the Data +Increase or -Decrease
keys.
THCV - Throttle Curve
The throttle & pitch curves are tied to the position of the
collective stick, and are specified at five points labeled 1
through 5 below. These "curves" are really straight lines
connecting the settings at the five points, and are defined by
assigning servo movement percentages to five positions of the
left stick: lowest = Point 1, the 1/4-up stick position = Point 2,
half-stick = Point 3, 3/4 position = Point 4, and top position =
Point 5. With the numbers defined as shown, the servo would
move 50% of full travel to one side at low collective stick
position, and 50% of full travel to the other side at high stick
position.
PTCV - Pitch Curve
Like the throttle curve described previously, pitch curves are
tied to the position of the throttle collective stick, and are
specified at five points labeled 1 through 5 below. Setup
instructions are the same as those for throttle curve, except
that you may also input a curve for the throttle hold/ST3 flight
mode.You can get a linear response by making the five settings
line up as shown above. But if you want another shape, you're
free to do it. You can "flatten out" or "soften" the curve around
hover, which is handy for making the control less sensitive there.
S/W SEL -
Switch Selection For Auxiliary Functions
Your Optic system allows you customize your radio and choose
what switches are used to turn on the following helicopter
functions: AIL D/R, ELEV D/R, RUDD D/R, R->T, HOLD, PMX1,
and PMX2. Note that each of these functions may be chosen
to be turned on by flipping a switch. Some may be selected to
be on all the time.
You can get a linear response by making the five settings line
up as shown above. But if you want another shape, you're

5. Repeat this procedure for Points 3, 4, and 5 by pressing the
Cursor Right key, then adjusting as desired with the Data
+Increase or -Decrease keys.
