The programming procedure in detail
Start by switching to the desired fl ight phase, e. g.
“normal”.
The throttle / collective pitch stick can now be used to
move the vertical line in the graph between the two
end-points “Point 1” and “Point 5”; at the same time the
momentary position of the stick is displayed in numeric
form in the “Input” line (-100% to +100%).
The point where the vertical line crosses the curve is
termed the “Output”, and this point can be varied within
the range -125% and +125% at a maximum of fi ve refer-
ence points. This control signal, modifi ed in this way,
affects the collective pitch servos only. In the picture on
the left the stick is exactly at the 0% position at “Point
3”, and also generates an output signal of 0% due to the
linear nature of the graph.
By default only points “1” (collective pitch minimum at
-100%), “3” (hover point at 0%) and “5” (collective pitch
maximum at +100% travel) are active.
To set a point you use the associated stick to move the
vertical line to the point you wish to change. The number
and current curve value of this point are displayed in the
bottom line in the left-hand half of the screen. The rotary
cylinder can now be used to change the current curve
value in the highlighted fi eld to any value within the
range -125% to +125%, without affecting the adjacent
points.

In this example we have moved reference point “3” to
+75%.
However, points “2” and “4” can optionally be activated,
even though they are disabled by default:

This is accomplished using the stick to move the vertical
line to the appropriate area. As soon as the message
“inactive” appears in the highlighted value fi eld, you
can activate the associated point by turning the rotary
cylinder; it can then be adjusted in the same manner as
the other points …

Points “1” and “5”, however, CANNOT BE DISABLED.
Note:
The following illustration, and all the other pictures on
this page, show a control curve which we prepared for
illustration purposes only. Please note that the curve
characteristics by no means represent real collective
pitch curves!
