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.

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

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

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 key, then adjusting as desired with the Data

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 mode.

Flip the switches as necessary to get into the new modes,
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.
