Notes:
If you reposition the point horizontally further away •
from the current control position than approx. ±25%,
a "?" sign re-appears in the line. This question mark
does not refer to the repositioned point, however:
instead, it signifi es that a further point can be set at
the current control position.
Please note that the percentage value on the
•
"Output" line always relates to the current joystick
position and not to the position of the point.
Smoothing the curve
This "jagged" curve profi le can be smoothed
automatically simply by pressing a button.
Then use the arrow keys on the left or right touch pad
to move the marker frame in an upwards direction to the
"Curve" line, as required. Now briefl y tap the center
SET
key on the right touch pad to activate the value fi eld on
the "Curve" line:

Subsequent aero-tow fl ying has proven that you
always have to fl y with the up-elevator held slightly in
during the tow. The solution will be to set up a mixer
that applies slight up-elevator trim to the elevator
servo connected to receiver output 3 when the aero-
tow release is closed. The screen-shot will be familiar
from page 182: here, the fourth linear mixer has been
set up for this function, with the switch channel "S"
as mixer input: Move the selected switch to the OFF
