Note:
The "Brake settings" menu is switched "off" if: "Motor
on C1 forward / back" in the »Model type« menu
(page 94) AND the "Motor" column of the »Phase
settings« menu, (page 142) are set to "yes" for the
currently active fl ight phase. Change the fl ight phase,
if applicable.

Similarly, a modern, tapered fl ying 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 center 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
exterior ailerons, on the other hand, the effect is just
the opposite: A downward throw shows an elevator
effect 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 joystick defl ection in the
height/depth direction, "everything" is possible here.

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
arrangement 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 fl ights with a setting of 0 %! Over
the course of the further fl ight 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 benefi cial.

… 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 fl ying curves, the respective exterior rudders
will have a greater curve radius than the interior
rudders, so this is comparable to the front wheel
positions on a car when driving in curves.

If these two rudders are also to defl ect outward upon
actuation of a brake system with the C1 joystick,
this can be achieved, for example, by setting an

¼ 5" with an appropriate travel
setting. Set the mixer's offset according to personal
preference, "front" (+100 %) or "rear" (-100 %),
because the winglet rudder should defl ect outward
only for proportional extension.
Independent of this, fi nish 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 fl ight-phase
independent menu …
