This "angular" curve profi le created in the example
can be smoothed automatically simply by pressing a
button. Do this – from a situation as illustrated – with a
brief tap on the d selection key of the left touch pad.
This will result in a switchover from "(Curve) off" to
"(Curve) on" (or vice versa):

Examples:
To open and close an aero-tow, a switch, e.g. SW 1.

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 194: 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 position and then switch …
