Suggested  names:  E-heli,  E-glider  if,  for  example, 
you wish to use different assignments for your electric 
models to their equivalents with I.C. motors. 
 Tip: we recommend that you set up the list to cover 
the most complex model which  you own  in that  par-
ticular category. For example, it presents no problem 
if  the  Glider  list  includes,  say,  assigned  transmitter 
controls for flaps and retractable  wheel, even if  your 
current model is just a simple rudder / elevator glider. 
11.3.8.  Summary: “Global assignments” 
  Five global assignment lists are available. 
  Three assignment lists are pre-defined. 
  All list names and assignments can be changed. 
11.4.  Global mixer definitions 
11.4.1.  Why “global” mixer definitions? 
As  in  the  case  of  assignments,  there  are  particular 
mixer  configurations  which  modellers  use  again  and 
again. For this  reason  we  have  separated  the  mixer 
definitions  from  the  process  of setting up  the  indi-
vidual mixer input values for a particular model. 
The  definition  is  entered  “globally”  in  menu  L 
(Setup),  Mixer  def.  (see  illustration  below).  Once 
defined, a mixer can be used as often as you like for 
any number of models. 
When a mixer is defined, the following points are de-
termined: 
1. A name for the mixer. 
2. A maximum of five mixer inputs. 
3. A switch for the mixer inputs. 
4. The method of working of the mixer inputs.

for each model in the menu £Mixer.

the method of working of the selected mixer input and 
the meaning of the variable values. 
11.4.2.  Which global mixers are available? 
The ROYAL SX 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  ( 22.2.)  “Pre-defined 
mixers” for information on the default mixer definitions. 
  Tip:  the  mixer  definition  should  cover  the  most 
complex 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.
