Setting Up The Throttle Curve
1. Press one of the Up Down EDIT buttons until the T.CV
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-1) 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)!
3. You begin a point 1, which will be blinking. This is the idle
position and will have a default value of 0%. Press the
DATA +Increase or -Decrease button to change the setting
to your desired value, try about 15 to 20% to start with.
4. When you're finished with Point 1, move to the next point
with the CURSOR Right button. The number 2 position will
be blinking and that 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 by pressing the
CLEAR button, and then changing the value with the
DATA +Increase or -Decrease button.
T.CV (Throttle Curve)
The throttle & pitch curves are tied to the position of the Throttle
/ Collective stick, and are specified at five points labeled 1through
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 stick position = Point 1,
1/4-up stick position = Point 2,
Half-stick = Point 3,
3/4 position = Point 4,
Top stick 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.
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 as
shown here.
This is handy for making the control less sensitive around hover.

5. Repeat this procedure for Points 3, 4, and 5 by pressing the
CURSOR Right button, then adjusting as desired with the
DATA +Increase or -Decrease buttons.
6. When you've completed the settings for the Throttle curves
in the first flight mode (NOR), go the Pitch Curve section and
setup the pitch curves for the NOR mode.

Tip
Setting "Idle-Up" curves up in other flight modes
After you learn to fly well in the "NOR" mode, consider
programming the "Idle-Up" curves for doing more advanced
aerobatic or 3D maneuvers. Use the settings in the NOR
curve as a basis for the other flight modes used by
advanced heli pilots.
