Dual Rate / Expo - fixed-wing model
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.

Simultaneously touching the or buttons of the
right-hand touch-key (CLEAR) resets an altered value in
the highlighted input field to 0%.
Examples of different Expo values:
Servo travel

Expo = +100%
Expo = +50%
Expo = –100%
In these examples the Dual Rate value is 100% in each
case.
… and assign a physical switch as described in the sec-
tion “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 of the switch. Select the left-hand column,
marked DUAL at the bottom edge of the screen, and set
the values for each of the two switch positions sepa-
rately in the highlighted field using the arrow buttons of
the right-hand touch-key.
Simultaneously touching 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
Combined Dual Rate and Expo
If you enter values for both Dual Rates and Expo, the
two functions are superimposed as follows:
