Aile diff - Plane
Aileron Travel and Differentiation Settings
This submenu option is not available for models using
the 1AILE and 1AILE1FLAP settings.
An aileron deflected downward generates greater
aerodynamic resistance than one deflected upward.
The asymmetrical resistance generates torque around
the vertical axis which causes a turning out of the in-
tended flight direction. This is a naturally occurring
phenomenon for all winged models, however the
effect comparatively is stronger on the longer glider
wings and less on motorized airplanes whose lever
arms are typically much shorter. This undesirable
side-effect is called “adverse yaw” and must be com-
pensated for by a simultaneous, counteracting rudder
deflection.
The rudder deflection also generates additional resis-
tance and further impairs flight. If the rudder deflec-
tion is differentiated so that the downward deflection
of the aileron is less than the upward deflection, the
adverse yaw can be reduced or eliminated without
having to manually compensate the rudder each time
on the aileron control.

Phase-Dependent Settings
This submenu allows for different phase-specific val-
ues to be programmed. Phase names are displayed
in green in the upper left side of the screen next to
the BACK button. Standard default naming for the
phases are usually displayed as NORMAL/PHASE
1. (Additional phases will be named numerically, e.g.
Phase 2, Phase 3, etc.) To define multiple phases,
refer to the FUNCTION submenu Phase section (page
120). Each new phase will need to be assigned to a
different switch. To change the phases, activate the
corresponding switch(es).

Notice
The available setting options depend on the
number of ailerons selected during the basic set-
tings of the model (BASE submenu Model Type).
Programming
The adjustment range of 100% to both sides allows
the adjustment of different deflections on the right
side independent of the rotation direction of the ai-
leron servos. 100% (travel) corresponds to normal
deflection (no differentiation), and 0% (travel) corre-
sponds to the split function.
High absolute values are required during stunt flying
in order for the model to rotate precisely around the
longitudinal axis when the aileron is deflected. Aver-
age values of about 50% are typical for supporting
curved flight in a thermal air current.
