f) Dual Rate/Exponential Setting "Dual rate/exp."
The Dualrate Function:
The dual rate function allows you to reduce the servo deflections of channels 1, 2 and 4 by operating the flight
condition switch. You can do this to simply and easily reduce the reaction sensitivity of a model which reacts too
aggressively at full extension. Especially for beginners, models with reduced rudder deflections are a lot easier to
control.
When a model is used for the first time, it might not yet be clear how sensitively it responds to the control commands.
Therefore it is a proven method to reduce the deflections during flight.
Exponential Function:
In contrast to the dual rate function, the end deflections of the servos are not reduced in the exponential function. The
exponential function merely reacts to the middle range of the control curve. In practice, this means that the reaction to
the control stick is no longer linear,. but forms a curve.
Setting the Dual Rate/Exponential Function
• Switch on the transmitter and call the function setting menu.
• Move the cursor arrow to the menu item "Dual rate/exp." with the scroll
wheel.
• Briefly confirm the scroll wheel button or the OK button to activate the
menu item.
The display shows the displays for the dual rate and exponential functions
for channel 1. At the same time, a control curve diagram and the flight
condition "Normal" are displayed.
In the flight condition "Normal", reduced rudder deflections are set, in flight
condition "Sport", larger ones are used.
• Turning the scroll wheel selects the channel in which the dual rate and
exponential values for the flight condition "Normal" are to be set.
• When pushing the scroll wheel button, the cursor arrow will jump to the
dual rate setting value.
• Turning the scroll wheel now permits setting the reduced servo deflection
now. The slant of the control curve changes according to the setting.
• When pushing the scroll wheel button again, the cursor arrow will jump to
the exponential setting value. Turning the scroll wheel now permits setting
the shape of the control curve.
If a negative setting value is selected, the curve shape becomes flatter in
the middle area. If a Positive setting value is selected, the curve shape
becomes steeper in the middle area.
