graph (pressing CLEAR = 100%).
Examples of different Dual Rate values:
Caution:
In the interests of safety the Dual Rate value should
always be at least 20% of total control travel.
Exponential function
If you wish to switch between two possible settings,
select the
fi eld and assign one of the availab-
le switches, as described on page 32. The assigned
switch appears in the screen display together with a
switch symbol which indicates the direction of operati-
on when you move the switch.
For example, the system enables you to fl y with a li-
near curve characteristic in the one switch positi-
on, and to pre-set a value other than 0% in the other
switch position.
To change the Expo value, fi rst select the right-hand
SEL fi eld, then use the rotary control in the highligh-
ted fi eld to set separate values for each of the two
switch positions, e.g. in the “normal” fl ight phase:
100% 2 +100%
«Normal »
SEL SEL
100%
0%
100% 0%
DUAL EXPO
Aileron
Elevator
Rudder
The Expo curve is displayed simultaneously in the
graph. (Pressing
CLEAR = 0%).
Examples of different Expo values:
In these examples the Dual Rate value is 100% in
each case.
Combination of Dual Rate and Expo
If you have assigned Dual Rates and Expo to the
same switch, both functions are switched simultane-
ously, e. g.:
Asymmetrical setting of Dual Rate and Expo
If you wish to set asymmetrical Dual Rate and / or
Expo values, i. e. varying according to the direction
of stick movement, you must move to the »
Control
switches « menu and assign, say CONTROL 3 (ele-
vator stick) to one of the control switches G1 … G8,
but leave the switching point at the neutral point of the
stick. Now return to the »
Dual Rate / Expo « menu
and select the corresponding control function, in this
case “Elevator”. Activate “Switch assignment”, and
move the transmitter control you just selected.
Move the elevator stick to the appropriate end-point,
and enter the Dual Rate and / or Expo value for each
side of neutral, e. g. for …
“up-elevator”:
100%
100%
+ 30%
