An aileron defl ected downward generates greater
resistance for aerodynamic reasons than one defl ected
upward.
Given this asymmetrical resistance, torque is generated
about the vertical axis which causes a turning out of
the intended fl ight direction. This undesirable side-effect
is also determined adverse yaw. This effect naturally
occurs more strongly on the comparatively long wings
of gliders than with motorized airplanes with their
generally much shorter lever arms, and normally must
be compensated by a simultaneous, counteracting
rudder defl ection. This rudder defl ection also generates
additional resistance and impairs fl ight.
If the rudder defl ection is differentiated so that the
downward defl ection of the aileron is less than the
upward defl ection, the adverse yaw can be reduced or
eliminated. In order for this to work, each aileron must
have its own servo that can also be installed in the
wings. The shorter linkages yield the additional benefi t
of more consistent aileron positions that have less play.

The conventional differentiation that is now provided by
the transmitter has signifi cant advantages over earlier
mechanical solutions that were generally permanently
set while building the model and generated additional
play during operation in cases of strong differentiation.
Now, the degree of differentiation can be changed at
any time, and downward aileron defl ections can be
entirely suppressed in the so-called split position. This
reduces or suppresses adverse yaw and can even
generate positive yaw in certain instances to cause
rotation about the vertical axis in the direction of the
curve in response to an aileron defl ection. In large
gliders, smooth curves can be easily generated using
just the ailerons.
Flight-phase-dependent settings
If you have created Quick Links in the submenu
"Q.Link", page 132, and have assigned an appropriate
name, it appears at the top right in green font such
as "NORMAL". Activate the corresponding switches if
desired to switch between Quick Links.

Note:
The available setting options depend on the
number of ailerons selected in the "Model
Sel" or "Model Type" menu.
The adjustment range of 100% to both sides allows
you to adjust different defl ection on the right side
independent of the direction of rotation of the aileron
servos. 100% (travel) corresponds to normal defl ection
(no differentiation), and 0% (travel) corresponds to the
split function.
High absolute values are required during stunt fl ying
in order for the model to rotate precisely about the
longitudinal axis when the aileron is defl ected. Average
values of about 50% are typical for supporting curved
fl ight in a thermal. Split position (0% travel downward) is
useful in ridge soaring if you want to execute a turn with
just the ailerons.
