11.4.2. Which global mixers are available?
The ROYAL
pro includes fourteen free mixers. Five of
them are pre-defined, and can be used immediately.
All the mixers - including the pre-defined ones - can
be changed exactly as you wish.
Please refer to the overview (Î 22.2.) “Pre-defined
mixers” for information on the default mixer definitions.
 Tip: the mixer definition should cover the most com-
plex application for which you are likely to want to use
the mixer. If the model is a glider whose ailerons you
“only” wish to raise for landing, you can use the
AILERON+ mixer. The inputs Flap and Ele -tr can
simply be left at “OFF” when you are setting up the
mixer inputs in the menu £Mixer. However, those
inputs remain available in the definition even though
they have no effect on the present model, assuming
that they are not set up and activated for that model.
11.4.3. Mixer names with a “+” suffix
You will see a “+” suffix attached to the names of the
pre-defined mixers. This indicates that, for example,
the AILERON+ mixer includes other inputs in addition
to the basic Aileron function. These mixer names are
also displayed in capital letters (ELEVATR+, AILERON+,
FLAP+, …), to differentiate them more clearly from the
basic inputs (Elevator, Aileron, Flap).
11.4.4. How are the free mixers used in fixed-
wing model aircraft?
You might care to think of the free mixer definitions as
a collection of building blocks, from which you select
the most suitable for any particular model. The “se-
lecting” is carried out when you assign the servos in
the model. Only if a mixer is assigned to at least one
servo (menu ¤Servo, Assignment) does the mixer
appear in menu G (Mixer); you can then set the values
for the individual mixer inputs.
The illustration below shows the building block collec-
tion and the fourteen mixer building blocks:

Important: a maximum of five free mixers can be
used simultaneously in any one model memory.
11.4.5. How are mixers used in helicopters?
For model helicopters the mixers required to control
the various rotor head types and the tail rotor are pre-
programmed as standard. As a result, the free mixers
(1 to 14) cannot be used when assigning the servos
for model helicopters.
However, there are three free transmitter control mix-
ers, and they can be used to mix the signals from the
controls ROLL, PITCH and YAW into the transmitter con-
trols ROLL, PITCH, YAW, THROTTLE or COLLECTIVE
PITCH.
The most important application for these facilities is
the various compensation mixers, in which all the con-
trol functions are mixed into THROTTLE. For exam-
ple, these mixers make it possible to compensate for
the increased power requirement when the pilot
makes deliberate control commands.
The settings in these mixers might look as follows:

Aileron ™ -> Throttle
Travel – 10%
Elevator™ -> Throttle
Travel – 10%
Rudder š -> Throttle
Travel+ – -5%
Travel- – 17%
Roll and Pitch (-axis) are mixed into Throttle
symmetrically. Separate values for “left” and “right”
can be entered for yaw.
11.4.6. Summary of the “free mixers”
x Fourteen free mixers are available.
x Mixer names (max. eight characters), mixer inputs,
switches and method of working can be changed
in all mixer definitions.
x Up to five free mixers can be used simultaneously
for a particular model.
x Every mixer you use can be assigned to as many
servo channels as you wish.
x The menu £Mixer only displays those mixers to
which at least one servo has been assigned.
x Only Control mixers are available for helicopters.
11.5. Model templates
11.5.1. Why are model templates needed?
The model templates make it much easier and quicker
to set up new models, as a large part of the routine
work is accomplished just by selecting the appropriate
template. Use a template, and you can immediately
start entering the settings for the model.
The model templates themselves cannot be changed.
However, when you set up a new model and load a
copy of the template into the model memory, you can
then access it and make changes as needed.
Advantage: since the template itself cannot be al-
tered (even accidentally), it is always available in the
exact form described in the Manual.
