concerned.
Whichever switch has been assigned … the respective
switch will appear in the display together with a switch
symbol indicating the switch’s direction if actuated, e. g.
in the «Normal» flight phase.

Select the right-hand column at the lower edge of the
display marked with SEL and activate the value field
with a brief tap on the centre SET key of the right four-
way button, the selection keys on the left or right four-
way button can now be used to alter the EXPO value
shown in the highlighted field, separately for each of
the two switch positions.
Now, for example, there is an opportunity to fly with a
linear curve characteristic with the switch in one direc-
tion, and to preset a value other than 0 % for the other
switch direction:

At the same time, the Expo curve will be presented in
the graph.
A simultaneous tap on the or keys of the right
four-way button (CLEAR) will reset a changed entry
field value displayed in inverse video back to “0 %”.
Some examples of Expo values:
Servo travel
Servo travel
Servo travel
Stick deflection
Stick deflection
Stick deflection
Expo = +100%
Expo = +50%
Expo = –100%
In each of these examples, the Dual Rate value
equals 100 %.
Combining Dual Rate and Expo
If values have been entered for both the Dual Rate and
the Expo function, the effects of both functions will
overlap, for example, as follows:
Servo travel
Servo travel
Servo travel
Stick deflection
Stick deflection
Stick deflection
Expo = +100%, DR = 125%
Expo = +100%, DR = 50%
Expo = –100%, DR = 50%
Asymmetric setting of Dual Rate and Expo
To make an asymmetric setting, i. e. a Dual Rate or
Expo setting dependent on the direction of the respec-
tive stick, first access the »Control switch« menu and
assign one of the C1 … C4 control switches – “C3”, for
example – to the desired transmitter control, e. g. con-
trol 3 for the nick function. Do not change the switching
point for the stick’s neutral position (0 %). Now return
to the »Dual Rate / Expo« menu and select the corre-
sponding control function (“Nick” in this example).
Now, with a brief tap on the centre SET key of the right
four-way button, activate the switch assignment and
change to the expanded switches then use the selec-
tion keys to move on to the previously defined “C3”
control switch:
