Combined Dual Rate and Expo
If you enter values for both Dual Rates and Expo, the
two functions are superimposed as follows:

edge of the screen, and set the values for each of the
two switch positions separately in the highlighted field
using the arrow buttons
 or  of the right-hand
touch-key.
Simultaneously press the
 or  buttons of the
right-hand touch key ( CLEAR ) resets an altered value in
the highlighted field to 100%.
Caution:
For safety reasons the Dual Rate value should always
be at least 20% of total control travel.

Exponential function
If you wish to switch between two settings, use the 
button of the left or right-hand touch-key to move to the
right-hand column, marked at the bottom edge of the
screen with the switch symbol
, then briefly touch
the central
SET
button and assign a switch to the func-
tion, as described in the section “Assigning switches
and control switches” on page 57. The assigned switch
appears on the screen together with a switch symbol
which indicates the direction of operation when you
move the switch.
For example, the system enables you to fly with a linear
curve characteristic in the one switch position, and to
pre-set a value other than 0% in the other switch posi-
tion.
Select the right-hand column, marked with EXPO at
the bottom edge of the screen, in order to change the
Dual-Rate value for each of the two switch positions in
the highlighted field, using the arrow buttons of the right-
hand touch-key.
