Menu: Mixer Helicopters; Comp. Mixer (Compensation Mixer) - Multiplex Royal SX 9 Instructions Manual

ROYAL SX
The next section explains the method of setting up a
"free mixer" using the example of the mixer AILERON+,
which is pre-defined as standard, and is used in several
model templates:
Mode of working of the input
Mixer inputs
Allocation indicator
This example shows the method of setting the mixer
AILERON+ ( the various aileron travels), as they might
be set up for a model glider with a four-flap wing.
What does the menu show?
The third line of this menu is a "dynamic" heading for
the parameter(s) of the marked mixer input. The in-
formation actually displayed at this point varies ac-
cording to the selected mixer input:
 On the left the screen shows the symbol for the
method of working of the mixer input ( 14.2.2.).
 The percentages indicate the significance of the
values. The possibilities are as follows:
----
No setting
trv'
Travel setting for asymmetrical inputs
trv#
Travel setting for asymmetrical inputs
trv
Travel setting for symmetrical inputs
offs

dead.
Deadband
pt1 Curve point for control centre position
pt2
Curve point for control end-points.
The bottom five lines display the following data:
 The transmitter control which generates the mixer
input
 % values of the mixer inputs:
Range: -100% OFF
 Status of the mixer inputs:
*
Mixer input active
-
Mixer input not active.
In the case of switched inputs:
G*
Switch G, input switched on
G-
Switch G, input switched off.
The Allocation indicator shows that the % values of
the mixer input can be allocated to one of the 3-D digi-
adjusters and - once unlocked - altered in flight ( 20.1.).
The defintions of the pre-defined mixers can be found
in the Section ( 22.2.).

Mixers which are always present:
The mixer Comp. Mixer (compensation mixer) is al-
ways available for model helicopters ( 16.2.1.).
Mixers which vary according to servo assignment:
Gyro and TAIL are always present in models based
on the HELImech or HELIccpm templates, as the
TAIL servo and Gyro servo (for gyro gain control) are
included in the templates. However, if you remove the
Gyro and / or TAIL servos from the servo assignment,
the associated mixers also disappear from the menu.
The Rotor head mixer appears if you have selected
HELIccpm as template, or if the HEAD f/b (front / back)
servos have been assigned to the mixer:

16.2.1.
This menu contains three transmitter control mixers.
In each case the Source is Roll, Pitch or Yaw (Ai-
leron, Elevator, Rudder).
As Target (destination) you can select from Roll,
Pitch, Yaw (Aileron, Elevator, Rudder),
and Collective pitch (Collect.):

Flight phase specific
Important: Roll and Pitch (Aileron and Elevator)
work symmetrically, and are based on a V-curve!
The mixer always works in the same direction, regard-
less of the direction of movement of the roll or pitch
stick.
Typical application: the mixer is always required to
compensate for increased energy requirement by ap-
plying more throttle, regardless of whether the roll
command is to right or left.
