1->4 — Aileron -> Rudder Mixing
Aileron-to-rudder mixing is a function which 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,
especially if a large amount of differential (more up aileron motion than down motion) is
present.
Nose points outside
circle: increase coupling
and/or differential
Coordinated turn: fuse
lines up with turn direction
(don't change anything)
Nose points inside
circle: too much coupling
or differential. Reduce one
or both.
Setting Up 1->4 Mixing (Rudder Coupling)
1. Use the MODE buttons until the 1->4 window appears, as shown. The
default is for the function to be inhibited, as shown. To activate, press the
press CURSOR key once, then press the (+) DATA INPUT key. The flashing
letters “INH” will turn to “ON.”
2. Press the CURSOR key once, and the plus or minus sign in front of the number will flash.
Move the aileron stick to the right (or left). If the rudder moves the same direction, proceed
to the next step. Otherwise, change the sign in front of the number by pressing one of the
DATA INPUT keys.
3. Press the CURSOR key once, and now the Percent sign will be flashing. Move the aileron
stick all the way to the right, and adjust the mixing amount by pressing the DATA INPUT keys.
You may set any amount between 0 and 100%. To return to the initial 50% value, pressing
both DATA INPUT keys.
