Unlike the »Channel 1 curve« menu, this display is
only associated with the control curve of pitch servos,
whereas the the "Channel 1 curve" affects all servos
controlled by the throttle/pitch joystick.
Note that the output signal of the "Channel 1
curve" option thus functions as an input signal for
the collective pitch curve programmed here: In the
graph, the vertical line is synchronized with the
throttle/collective pitch stick and therefore follows
the current Channel 1 curve characteristic.
The control curve can be defi ned (separately per
fl ight phase) by up to 8 points, termed "reference
points", placed at any point along the joystick travel.
Initially, however, fewer reference points are
adequate for setting up the collective pitch curve. We
recommend beginning with three reference points to
start with. These three points, namely the two end-
points "Pitch low (L)" (= -100 % control travel) and
"Pitch high (H)" (= +100 % control travel) plus a point
at the center of control travel still to be set, defi ne an
initially linear profi le for the pitch curve.

Programming details
First, switch to your chosen fl ight phase, e.g. «Normal».
The throttle/collective pitch stick is used to move
the vertical line in the graph between the two end-
points "Point L" (minimum pitch at -100 %) and "Point
H" (maximum pitch at +100 % control travel): at the
same time, the current joystick position is shown
numerically on the "Input" line (-100 % to +100 %).
The point at which the vertical line crosses the
curve is termed the "Output", and can be varied at
the maximum of 8 reference points within the range
-125 % to +125 %. A control signal modifi ed in this
way affects only the collective pitch servos.
In the example to the left, the joystick is at exactly 0 %
of control travel and also generates an output signal
of 0 %, since the characteristic curve is linear.
Up to six additional reference points can be set
between the two end-points "L" and "H", although the
distance between neighboring reference points must
not be less than approx. 25 %.

Setting reference points
Move the joystick. If the display shows a framed
question mark, then you can set the next reference
point with a tap on the center

The order in which up to six reference points
are generated between the end-points "L" and
are generated between the end-points "L" and
"H" is irrelevant since these reference points are
continuously renumbered automatically from left to
right as they are entered.

Confi guring reference points
To confi gure a point, use the joystick to move the
vertical line onto the point you wish to change.
The number and current curve value of this point
are displayed on the left side of the display, on the
"Point" line. Briefl y tap the center
vertical line onto the point you wish to change.
