The control surface travel generated by the aileron

The inputs Aileron, Spoiler and Flap are always
active (*). A value for travel is only set for Aileron
(100%). Since the method of working of the mixer input
is set to "symmetrical", the aileron travel is the same
up and down (Differential ( 12.6.)).
The Spoiler and Flap controls have no effect on the
AILERON+ servos (all inputs are OFF).
If the model has no airbrakes, the ailerons can be set
to deflect up as a landing aid (glide path control). In
the template 4 FLAPS, which we have used for the
new model, the mixer AILERON+ is assigned to the
aileron servos. This function is controlled by the
transmitter control Spoiler.
We use the term "spoiler" for the transmitter controls
and mixer inputs which are used as glide path control
or for "braking" the model (airbrakes, ailerons up, but-
terfly (crow)).
The landing aid (both ailerons up) is activated by set-
ting a value for the Spoiler input.
12.6.

Differential aileron travel

Aileron differential means: the travel of the down-
going aileron is smaller than that of the up-going one.
Differential is necessary because the down-going ai-
leron generates greater drag than the up-going ai-
leron, and this tends to counteract the desired direc-
tion of the turn. The model yaws (swings around its
vertical axis).
The Differential setting defines the percentage by
which the down-going aileron travel is reduced relative
to that of the up-going aileron. At 50% differential the
down-deflection is half as great as the up-deflection.
The higher the percentage value, the smaller the
travel of the down-going aileron.

If you set 100% differential, the ailerons only deflect
up; there is no down-travel at all. This special setting
is sometimes termed Split mode.
Aileron differential can be set to a different value for
each flight phase separately.
12.6.1.

Activating differential

Aileron differential is located in the Mixer menu.
a. Open the main menu G Mixer (press button G).
b. Select and open the Ail.Diff. menu,
select and open the Mode menu point:
£Ail.Diff..NORMAL
¨Exit
Mode OFF
Diff. — 50%
There are three different modes for Differential:
xOFF x
No differential.
ON x
Differential always effective with the value which is
set at Diff. (flight phase specific).
+SPOILER
When spoilers (or Butterfly) are extended, aileron
differential is suppressed in order to maintain ade-
quate aileron response on the landing approach.
c. Press ENTER (or press the 3-D digi-adjuster) to
close this menu point.
12.6.2.

Setting the differential value

a. Open the main menu G Mixer (press button G).
b. Select and open the Ail.Diff. menu, then select
and open the menu point Diff.:
£Ail.-Diff..NORMAL
¨Exit
Mode +SPOILER
Differ. —
This value applies for Flight Phase 2, NORMAL
50% is a useful starting point for carrying out ex-
periments with aileron differential.
!
If you allocate aileron differential to one of the
two 3-D digi-adjusters (-), you can adjust the value
while the model is in the air ( 20.1.).
