Combined Dual Rate and Expo
If you enter values for both Dual Rates and Expo, the
two functions are superimposed 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%
e. g. “switch back”:
SEL
88%

and after moving switch “2” to the “forward” position:

Exponential function
If you wish to switch between two settings, select the
fi eld and assign a switch as described on page 33.
The assigned switch appears in the screen together with
a switch symbol which indicates the direction of opera-
tion when you move the switch.

For example, the system enables you to fl y with a linear
cur
ve characteristic in the one switch position, and to
pre-set a value other than 0% in the other switch posi-
tion.
To change the Expo value, fi rst select the SEL fi eld,
then use the rotary cylinder in the highlighted fi eld to set
separate values for each of the two switch positions:
Pressing CLEAR in the highlighted fi eld resets an
altered v
alue to 100%.
Examples of different Expo values:

Expo = +100%
Expo = +50%
Expo = –100%
In these examples the Dual Rate value is 100% in each
case.
