Finally, the mix switch number to con-
trol mix-on or mix-off must be selected.
19. EXPONENTIAL FUNCTION (EXPO)
The “EXPO” function can
be used to determine the
amount of servo throw at
a particular stick position.
The linear action can be
modified into a gradual
exponential curve. This
allows a softer control
reaction around the stick
and servo neutral posi-
tion.
This option is available on all stick controls (1-4).
The exponential curve can be set both sides of control neutral:
• Positive curve-> exaggerated and sensitive control response
around neutral position (curve 1).
• Negative curve-> reduced and softer control response around
neutral position (curve 2).
• In both cases the servo end point throw remains unchanged.
• The straight line shows the normal, linear characteristic of the
stick to servo throw (Expo set at 0%).
This function must be selected with
the “MODE” key after activating the
programming mode. Press the “CUR-
SOR” key until “EXPO” menu appears
in the display. Subsequently, the
menu for adjusting Dual Rate appears
as shown in the neighbouring display
illustration.
The adjustment is made using an example for one of the stick
controls:
By use of the “CURSOR” key, select a channel (1-4) that you
would like to set the exponential throw. The particular channel
number selected will now flash in the display.
Using the “+” or “-“ keys, the “EXPO” adjustment can be set be a
positive or negative % value. The selected % age will appear in
the display.
The adjustment range of EXPO function lies between –100 and
+100 %. The factory default is set to 0% for all controls.
NOTE:
Exponential also reduces the trim value by the correspon-
ding amount; therefore a maximum of 50% EXPO should be used!
18. V MIXER (VMX 1-2)
Moving a transmitter control will nor-
mally move only that servo connected
to that channel number. If you want
one Tx control to move another chan-
nel simultaneously, you must use a V
mixer.
Some or all of the Tx controls may
be mixed with another channel. The
throw and direction of the mix can be adjusted individually.
The FC-16 software contains two V mixers with dummy functions.
You are able to mix two free controls with each other. The mixer
function can be switched on or off at any time by using an external
mixer switch. The use of an external mixer switch can also vary
the mix percentage varied with a mix controller. Furthermore, you
are able to define the amount of trim used. The use and adjust-
ment is the same for both V Mixers (VMX1-2). The mix switch and
controller are simply plugged into a different position on the PCB
sockets. (See chapter 25).
The mixing takes place with one control (Master) acting on ano-
ther control (Slave).
Navigate to the V-Mix 1 adjustment
menu by continuous pressing of the
“+” key (ON).
Cursor through the menu until “VMX1”
appears. Now the mix value (%) can
be set for control 1.
Repeat pressing the cursor to select
master channel “MAS”. Channels 1-8
may be selected as master.
Further pressing the cursor will select
slave “SLV”. Channels 1-8 may be
selected as slave.
