brak fl ap (Brake fl ap)
When you operate the brake function (C1 stick) both fl ap
servos move together for the landing approach; the mi-
xer ratio can be set to any value in the range -150% to
+150%. Down-fl ap is usually selected.
brak aile (Brake aileron)
When you operate the brake function, both aileron ser-
vos move together for the landing approach; the mi-
xer ratio can be set to any value in the range -150% to
+150%. It can also be useful to defl ect both ailerons up
slightly when the airbrakes are extended.
ail rudd (Aileron rudder)
In this case the rudder automatically “follows” when an
aileron command is given, and the mixer ratio (degree
of following) can be set by the user. Coupled aileron /
rudder (sometimes abbreviated to CAR; also known as
“combi-switch”) is especially useful for suppressing ad-
verse yaw in conjunction with aileron differential, and
this combination usually makes smooth turns very easy
to fl y. Naturally, the rudder can still be controlled sepa-
rately by means of its dedicated stick. If an (optional)
switch (SW 1 … 4) is assigned to this function, the mixer
can be switched on and off in fl ight, so that you can con-
trol the ailerons and rudder separately if and when you
so desire.
ail fl aps (Aileron fl ap)
This mixer feeds a variable amount of the aileron sig-
nal into the fl ap channel. When an aileron command
is given, the fl aps “follow” the ailerons, although usual-
ly through a smaller angle, i.e. the mixer ratio is gene-
rally less than 100%. The adjustment range of -150%
to +150% allows the user to set up the fl ap direction to
match that of the ailerons.
Note:
If your model is equipped with only one fl ap servo, you
should still select “... 2FL” in the “aile/fl ap” line of the
»Base settings« menu (see page 39) but leave the “Ail
Flap” mixer at 0%. In contrast, all the other wing mi-
xers can be used in the usual way.
brak elev (Brake elevator)
Extending any form of airbrakes usually generates an
unwanted change in pitch trim (nose up or nose down);
this is especially marked when a butterfl y (crow) braking
system is deployed (see next page).
This mixer feeds a corrective signal to the elevator to
compensate for this unwanted moment. The adjustment
range is -150% to +150%, but “usual” values are gene-
rally in the low double fi gures.
