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 is turned on and off by the Rudder D/R switch.

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 either the ON indicator or the OFF
indicator will be flashing, depending on the position of the Rudder D/R switch.

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 0 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.
