You can ignore all other settings in this menu.
Note:
The "Brake settings" menu is switched "off" if:
"Motor on C1 forward / back" in the »Model
type« menu (page 104) AND the "Motor"
column of the »Phase settings« menu, (page 154)
are set to "yes" for the currently active flight phase.
Change the flight phase, if applicable.
Similarly, a modern, tapered flying wing air craft can
also be operated. With some of these models there
are also interior and exterior rudders: The prior is in
front of the centre of gravity and the latter is behind.
A downward throw of the central rudder(s) increases
the ascending forces and has an elevator effect. An
upward throw has the opposite effect. On the exte-
rior ailerons, on the other hand, the effect is just the
opposite: A downward throw shows an elevator ef-
fect and vice versa. With appropriate adjustment of
the "leading" mixer to the setting of curve mixers in
order to achieve a supporting effect from the external
rudder pair with only extreme stick deflection in the
height/depth direction, "everything" is possible here.
The author of this manual uses a curve mixer for his
model, which is defined by a total of four points:

In this example the two interpolation points 1 and 2
are each at 0 % as well as the left edge point at +60 %
and the right edge point at -65 %. In conclusion, the
curve was rounded.
In this case: Regardless of which type of servo ar-
rangement was selected, any type of differentiation
should be set with caution! On a tail-less model,
differentiations show a single-sided height/depth
elevator effect, so we urgently recommend beginning
at least the initial flights with a setting of 0 %! Over
the course of the further flight testing, under certain
circumstances it may be advantageous to experiment
with differentiations deviating from zero.
With larger models, rudders in the winglets - the
"ears" mounted on the wing ends - can be beneficial.
If these are controlled with two separate servos, with
the use of one of the mixers in the menu ...
»Dual mixer«
... the rudder signal can be "split" very easily and
even differentiated, whereby the second rudder servo
is connected to one of the still free receiver outputs.
For a model with a "Delt/fl.wing" tail type, receiver
output "5" should still be unoccupied and it can then
be used as indicated below:

Differentiation is necessary in this case because,
when flying curves, the respective exterior rudders
will have a greater curve radius than the interior rud-
ders, so this is comparable to the front wheel posi-
tions on a car when driving in curves.
Note:
The rudder can only be differentiated as
programmed above!
If these two rudders are also to deflect outward upon
actuation of a brake system with the C1 stick, this
can be achieved, for example, by setting an additional
mixer "C1 5" with an appropriate travel setting. Set
the mixer's offset according to personal preference,
"front" (+100 %) or "rear" (-100 %), because the wing-
let rudder should deflect outward only for proportional
extension.
Independent of this, finish up by uncoupling the
"false" control function from the control channel
to which the second servo was connected – even
though all inputs in the »Control adjust« menu are
"free" by default – by way of the flight-phase independ-
ent menu ...
»MIX-only channel«
... for safety's sake! In keeping with the above exam-
ple, control channel 5 should therefore be set to "MIX
only".
