Good to know:
What is a mixer?
Each model memory has 8 freely programmable linear mixers, 4
freely programmable curve mixers and 4 cross-mixers. These mixers
allow a control signal from one control to be mixed with another
channel. Depending on the type of mixer, this can be adjusted lin-
early, in the form of a curve or crosswise.
There are pre-programmed mixers in the "Wing mix" menu.
Wing Mix
The mixers that appear in this menu are dependent on the settings
in the "Model type" menu. The individual options of the "Wing mix"
menu are described separately according to 1-, 2- and multi-flap
models.
Principle differentiation of ailerons and flaps
Aile.diff. /Diff.
The aileron differentiation is used to compensate for the negative
winding torque occurring with the aileron extension. In this case, the
path of the aileron, which moves downwards, is correspondingly
reduced. The aileron differentiation should always be used with all
gliders. The aileron differentiation also works with motorl models
depending on the airfoil profile. The adjustment range of ±100%
allows you to adjust different deflection on the right side, indepen-
dent of the direction of rotation of the aileron servos. 0% corre-
sponds to normal deflection (no differentiation), and -100% or +100%
corresponds to the split function.
Diff.
In the top line "AILE" of the multi-flap menu (described later),
set the percentage of the flaps the ailerons are affected by the aile-
ron control stick. Two-line underneaths, in the line "Diff." adjust the
flap differentiation to compensate for the aileron deflection of the
flaps. The adjustment range of ±100% allows a correct adjustment
of the differentiation independent of the direction of rotation of the
servos. A value of 0% corresponds to the normal turning. The servo
travel downwards is equal to the servo travel upwards. -100% or
+100% means that the path downwards is reduced to zero ("split"
operation) in the aileron control of the flaps.
