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

Expo = +100%, DR = 125%
Expo = +100%, DR = 50%
Expo = –100%, DR = 50%

edge of the screen, and set the values for each of the
two switch positions separately in the highlighted fi eld
using the arrow buttons cd or ef of the right-hand
four-way button.
Simultaneously press the cd or ef buttons of the
right-hand four-way button (CLEAR) resets an altered
value in the highlighted fi eld to 100%.
Caution:
For safety reasons the Dual Rate value should always
be at least 20% of total control travel.
Examples of different Dual Rate values:

If you wish to switch between two settings, use the f
button of the left or right-hand four-way button to move
to the right-hand column, marked at the bottom edge of
the screen with the switch symbol
, then press the
central SET button and assign a switch to the function,
as described in the section “Assigning switches and
control switches” on page 39. The assigned switch ap-
pears 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 fl y 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 fi eld, using the arrow buttons of the right-
hand four-way button.
