ileron Rudder Mixing
A
ileron-to-rudder mixing is a function that causes the rudder to
move
automatically with the motion of the aileron stick. This is
done
because when ailerons are used to command a turn, the
down-moving
aileron has more drag than the up-moving one,
so
the plane's fuselage tries to yaw against the turn. Adding
rudder
mixing cures this problem by making the fuselage point
straight
into the oncoming air stream (this is also called
"coordinating the turn").
The slower the model flies, the more mixing is needed, and the
faster
it moves, the less is needed. It is ideal to make slow-
flying
scale models fly realistically. The amount of coupling is
highly
dependent on the model configuration. Usually only a
small
amount of rudder is needed. It will also help to set up
some
aileron differential using the EPA menus. A good
starting
point is to limit the ailerons' down motion to 50% to
75% of the up-moving aileron's motion.
The aileron-to-rudder mixing function may be on always, or
may
be turned on and off using Switches 1, 2, 3, or 4. You
may
choose how in the S/W SEL menu.
either the ON indicator or the OFF indicator will be flashing,
depending
on the position of the ON-OFF switch that is
selected.
See the Switch Select instructions on P. 39 for
information
on how to select the ON-OFF switch.
Flashing
2. Press the Cursor Right key once, and the Percent sign will
be
flashing. Move the aileron stick all the way to the right,
and
adjust the R/D mixing amount by pressing the Data
+Increase or -Decrease key. You may set any amount
between
-100 and 100% (an initial value of 10-20% is
suggested).
To return to the initial 0% value, press the
Active/Inhibit (Clear) key.
3. Move the aileron stick all the way to the left, and adjust the
L/U mixing amount in the same way. To return to the initial
0% value, press the Active/Inhibit (Clear) key.
E->F - Elevator Flap Mixing
Elevator-to-flap mixing makes the flaps drop or rise wheneve
r
you pull on the elevator stick. It is used to make tighter "pylon
"
turns or squarer corners in maneuvers. Elevator-to-flap mixin
g
is set up so that the flaps droop (are lowered) when up elevato
r
is commanded.

Notice that this mixing function works with the flaperon setting
.
If flaperon mixing (FLPN) AND E->F mixing are activated, whe
n
you pull up elevator, BOTH ailerons will droop. This function i
s
turned on with the Flt. Mode (SW-4) switch fully forward.

Reduce one or both.
Setting Up A->R Mixing (Rudder Coupling)
1. Press one of the Up Down Edit buttons until the A->R
window appears, as shown. The default is for the function
to
be inhibited, as shown. To activate, press the Active/
Inhibit (Clear) key. The letters " INH " will turn to " 0 ," and
Setting Up E F Mixing
1. Press one of the Up Down Edit buttons until the E->F
window appears. The default is for the function to be
inhibited.
To activate, press the Active/Inhibit (Clear) key.
This
will cause he INH display to change to a number display,
and
either ON or OFF will be flashing either the ON indicator
or
the OFF indicator will be flashing, depending on the
position
of the ON-OFF switch that is selected. See the
Switch Select instructions on P. 39 for information on how
to select the ON-OFF switch.
