owner of a superb system for the newcomer to the
hobby of radio-controlled modelling. We hope you
have many hours of fun and success with your new
equipment.
2. Q
UICK
-S
TART
1. Unpack the transmitter and receiver
Store the documents safely.
2. Insert the batteries
It is essential to maintain cor-
rect polarity (see adjacent illus-
tration). Reversed polarity may
ruin the transmitter and / or the
cells.
3. Binding
• Preparing the model
When binding is complete, the receiving system
immediately starts operating. Secure the model
carefully so that no damage can result if the propel-
ler should start turning.
• Prepare the transmitter
Hold the multi-function
button pressed in and
switch the transmitter on,
then release the button
again. The LED flashes
at a high rate.
• Prepare the receiver
Switch the receiver on
with the SET button held
pressed in; the receiver
LED now flashes at a
high rate.
If binding is successful, both LEDs revert to a slow
flashing rate.
4. Check the directions of servo rotation
• Model with ID receiver
The transmitter emits an audible signal when it de-
tects the receiver. No further adjustments are re-
quired.
• Model with normal M-Link receiver (light or teleme-
try)
All the control surfaces (servos) must respond to
the sticks in the correct direction; check and re-
verse the servos if necessary: move the correct
stick to one end-point and hold the multi-function
button pressed in for
three seconds: the ser-
vo now reverses, and
moves to the opposite
end-point.
5. Carry out a range check
It is important to check radio
range before the first flight:
hold the multi-function but-
ton pressed in for two sec-
onds immediately after
switching on, and the LED
glows constantly. The transmitter now generates great-
ly reduced power, and emits an audible warning signal.

In this mode the control system must continue to
function up to a distance of about fifty metres.
6. Flying the model
These few steps are all you need to do before the
first flight. Be sure to keep to the correct se-
quence of switching on and off: always switch the
transmitter on first, and only then the receiving
system; reverse the sequence when switching off.
Before you launch and fly your model please read
through the manufacturer’s notes; those concern-
ing safety and other warnings are particularly im-
portant.
3. I
NTRODUCTION
These operating instructions are an integ-ral part of
the product, and contain important information and
safety notes. Please store them in a safe place, and
be sure to pass them on to the new owner if you ever
dispose of the equipment.
3.1 The SMART SX philosophy
The SMART SX M-LINK is a compact, intelligent six-
channel beginners’ radio control system with a
concept for the future!
The SMART SX intelligent beginners’ radio control
system is fully compatible with other MULTIPLEX sys-
tems, from the telemetry-capable COCKPIT SX right
up to the high-end PROFI TX system. The same ap-
plies to the small ID receiver supplied in the set, which
even works with the sophisticated PROFI TX transmit-
ter.
However, MULTIPLEX offers much more than this:
our range also includes a carefully considered, con-
sistent series of models. Our complete RTF (Ready-
to-Fly) packages contain the model, factory-assem-
bled and almost ready for the air, the SMART SX
transmitter, an RX-5 M-LINK ID receiver, dry cells, a
rechargeable flight battery and a 230 V battery
charger. Once you have unpacked the model, all you
have to do is attach the wings, charge the flight pack
and receiver battery (if used), and prepare the trans-
mitter. When these few procedures are out of the way,
there is nothing to stop you flying the model.
The presence of the M-LINK ID
receiver enables the SMART SX
to detect the specific model, and
automatically activate the as-
sociated settings from its enor-
mous reserve of model memo-
ries: fifty independent model
memories are available. All compatible MULTIPLEX
ELAPOR® models from RR+ to RTF are programmed
in the transmitter as standard. Many models from
other manufacturers can be fitted with an ID receiver,
and this makes it very simple for the intelligent
SMART SX transmitter to detect each ID receiver, and ex-
ploit its advantages. The overall concept of transmitter and
model expands with the demands of the model pilot. MUL-
TIPLEX offers a complete and consistent system whose
components are all compatible.
Once you have gained initial experience with an RTF mod-
el, and wish to own and fly another aircraft, we recommend
that you move on to a MULTIPLEX RR+ model. Our RR+
packages are just as complete as the RTF models, with the
exception of the SMART SX M-LINK transmitter and battery
charger, as you already own these two components from
your first RTF model. You can use them again, since the
transmitter and charger are fully compatible with the RR+
models. The transmitter detects all compatible RR+ models
which are currently available. When new models come onto
the market, you can load their settings into your transmitter
using the free MULTIPLEX Launcher software; this saves
you the task of making the adjustments yourself.
When your requirements have expanded to the point where
you are keen to invest even more time in the hobby of
model flying, you can easily upgrade to an even more pow-
erful MULTIPLEX transmitter, e.g. a COCKPIT SX system,
since all the receivers are compatible. This represents long-
term system compatibility, and saves you money.
3.2 Features of the SMART SX
The SMART SX M-LINK is a compact, intelligent six-chan-
nel beginners’ radio control system which includes ground-
breaking features, some of them patented.
• The transmitter exploits its intelligent patented model
identification system to assign a specific model (i.e. its
receiver) to a pre-programmed model memory. All
MULTIPLEX RR+ and RTF models are already prog-
rammed in separate model memories.
• The transmitter
is fitted with an
aerial incor-
porating the
newly patented
IOAT technolo-
gy. The opti-
mised direc-
tional charac-
teristics signifi-
cantly enhance
security, and take effective range far beyond the limits
of vision. The 2.4 GHz aerial integrated into the trans-
mitter case is always directed at the optimum angle,
and the radiated signal to the rear is minimal; all the ra-
diated power is effectively concentrated in the flying
sector.
• The small, light transmitter is very easy to handle, and
can be used for many types of model. Its ergonomically
efficient case is very comfortable to hold.
• Five fully proportional channels are available: elevator,
rudder and throttle plus two aileron channels. A

MULTIPLEX
switched channel can also be used, controlled by
the throttle function trim lever.
• All the primary control surface functions feature
digital trims.
• A buzzer is used to provide audible feedback to
the user, indicating the most important processes,
such as: detecting the ID receiver, range-check,
voltage monitor, trim function, Dual Rate setting,
model select.
• The transmitter software is carefully structured
with ultra-simple operation in mind. The simplicity
of operating the transmitter makes it extremely
easy to set it up to suit virtually any other model
from a huge range of manufacturers. The trans-
mitter even stores the final trim settings for each
specific model.
• The pioneering, ultra-secure M-LINK transmission
process with its intelligent channel management
system creates the best possible pre-conditions
for totally reliable operation. The M-LINK process
makes it possible to operate up to 150 models
simultaneously without mutual interference.
• With the three recommended AA-size dry cells
the SMART SX transmitter operates for the enor-
mously long time of up to 25 hours. The unit also
includes an integral voltage monitor with a war-
ning threshold set at a sensible level.
• It is possible to set up the transmitter to control al-
most any RC model currently available.
• The SMART SX transmitter is ideal for use as a
Pupil transmitter in a Trainer system, providing
the beginner with the perfect opportunity to learn
the initial steps in the art of model flying quickly
and safely. The wireless connection to the
Teacher transmitter requires the M-LINK Trainer
Stick - which can be used with any Trainer-
capable MPX transmitter fitted with a multi-
function socket - or a PROFI Tx using COPILOT.
• The transmitter software (= firmware) can be up-
dated using the integral interface located in the
battery compartment. This makes it possible to
keep the transmitter completely up-to-date at all
times. The same method can be used to transfer
the settings for new RR+ models into the transmit-
ter.

AFETY NOTES
,
OTHER INFORMATION
Radio-controlled models and the associated RC sys-
tems are not playthings in the usual sense of the term.
Building and operating them safely calls for a certain
level of technical competence and manual skill, to-
gether with discipline and a responsible attitude at the
flying field. Errors and negligence in building and fly-
ing the model can result in serious personal injury and
damage to property. Since neither we, as manufactur-
er, nor the retailer have any control over the construc-
tion, maintenance and operation of our products, we
are obliged to take this opportunity to point out these
hazards and to
emphasise your personal responsibility. We
deny all liability.
It really is essential to observe the following safety notes,
as you bear the responsibility for the safe operation of this
product:
• Please read right through these instructions, and do not
operate the system until you have studied the infor-
mation and the following safety notes.
• It is never permissible to make technical modifications
to the radio control system. Use genuine accessories
and replacement parts exclusively; these include trans-
mitter battery, receiver and servos.
• If you intend to operate the system in conjunction with
products from other manufacturers, you must ensure
that they are of good quality and work properly. Every
new or changed combination of components must be
checked exhaustively before use; the equipment must
work correctly and at full range. Do not operate the RC
system or the model if something is not in order. First
seek out and eliminate the problem.
• A model flying out of control for whatever reason can
certainly cause serious personal injury and property
damage. For this reason it is the modeller’s responsibil-
ity to take out third-party insurance for model aircraft,
and heed the regulations. This really is mandatory.
• Always keep to the correct sequence when switching
the system on and off, as this avoids the risk of the mo-
tor bursting into life unexpectedly:
- When switching on
Always switch the transmitter on before connecting
the flight battery or switching the receiving system on.
- When switching off
Always disconnect the flight battery or switch the re-
ceiving system off before switching the transmitter
off.
• Have your RC system - especially the transmitter and
receiver - checked at regular intervals (every two or
three years) by an authorised MULTIPLEX Service
Centre.
• The transmitter must be operated exclusively within the
stated temperature range. Please note that condensa-
tion may occur inside the transmitter if it is subjected to
a major change in temperature. Damp can affect the
operation of the transmitter and any other electronic
equipment.
• If moisture affects any electrical unit, cease operations
immediately, disconnect the power supply, and allow
the device to dry out completely, preferably with the
case open; this may take several days. After this carry
out a careful check of its functions. If you are still un-
sure, take the affected equipment to an authorised
MULTIPLEX Service Centre for checking.
In addition to these safety notes, please observe the follow-
ing points.
• Build your model with great care; this applies in particu-
lar if you have to repair your model. The responsibility
for completing the work competently rests with you.
• Install the servos and mechanical linkages in such a
way that the control surfaces deflect freely, and are not

MULTIPLEX
mechanically obstructed (stalled) at either end-
point (maximum travel).
• Adjust the horns, output arms and linkages as
accurately as possible, taking care to keep lost
motion (slop) to an absolute minimum. This
avoids overloading the servos, which are then
able to exploit their full potential performance.
These measures ensure that the servos have a
long useful life, providing the highest possible
margin of safety.
• Provide effective protection for the receiver, the
batteries, the servos and the other RC com-
ponents, and observe the notes in the operating
instructions supplied with them. An important fac-
tor in this is the correct balancing of propellers
and rotors. Any part of a power system which is
damaged or runs out of true must be replaced at
once.
• Do not place cables under strain, do not kink
them, and do protect them from rotating parts.
• Avoid unnecessarily long or superfluous servo
extension leads, and always use cable of ade-
quate conductor cross-section (voltage loss). We
recommend at least 0.24 mm2 as a starting point.
• Take appropriate measures to avoid interference
due to static charge, powerful electrical or electro-
magnetic fields (this includes the suppression of
electric motors with suitable capacitors), and keep
such sources well away from the RC system, the
receiver aerial, wiring and batteries.
• Maintain adequate spacing between cables which
carry high currents (e.g. electric power system
leads) and the RC system. In particular the cables
between brushless electric motors and their
speed controllers must be kept short (max. 10 to
15 cm if possible).
• Check all functions carefully, and ensure that you
are properly familiar with the method of operating
your transmitter before using it to control a model.
You should also examine your model at regular inter-
vals, checking the following points in particular:
• Check that control surfaces and linkages are free-
moving and devoid of lost motion (slop);
• Check that pushrods, other linkage components,
hinges, etc. are strong enough and in perfect con-
dition;
• Look for fractures, cracks and distortions in the
model, the RC components and the power sys-
tem;
• All cables and connectors must be in good con-
dition and make reliable contact;
• Check the condition of the power supply system
and wiring, including the switch harness, and the
external condition of the battery cells. This also in-
cludes the use of appropriate charging proce-
dures to match the battery type, and regular main-
tenance of the batteries themselves.
Pay particular attention to the system’s power sup-
plies: both in the transmitter and in the model.
• Remove the dry cells from the transmitter if you know
you will not be using it for a long period, as they could
leak and cause damage.
• Always fit new dry cells after a protracted period of non-
use.
• If you hear the voltage monitor warning sound, land
your model (or otherwise cease operations) immediate-
ly. Change the dry cells for new ones of the correct
type.
• Never attempt to recharge dry cells, as they could ex-
plode.
• At regular intervals check the state of the receiver bat-
tery or batteries, and the BEC system.
• Rechargeable batteries must be charged regularly;
never wait until the servos’ movements are perceptibly
slower. Make it a rule to charge your batteries before
every flying session.
• If you are using rechargeable cells, it is essential to ob-
serve the charging instructions provided by their manu-
facturer.
Before every flight carry out the following procedures and
checks:
• Carefully charge up the transmitter, receiver and flight
batteries, and check their state of charge regularly dur-
ing the session and between flights.
• When you arrive at the launch point, register with the
site warden or flight director, and do not switch ON until
you have checked with the other pilots present that
your channel is free.
• Check that all control functions and auxiliary functions
are working correctly and in the correct “sense” (direc-
tion).
If you discover a problem, do not launch the model.
First seek the fault, eliminate it, and check again.
When operating your model you should always observe the
following points:
• If you have no experience in flying a model aeroplane,
please ask a skilled pilot to help you initially. A Trainer
system is a great help during the early stages.
• Only fly your model at a suitable site. Never operate a
model in the vicinity of buildings or roads.
• Do not fly or steer your model over or towards spec-
tators. Never place people or animals in danger.
• Do not carry out any high-risk flying or driving manoeu-
vres.
• In Germany and in many other countries it is a legal re-
quirement to take out third-party insurance cover for the
operation of model aircraft. Find out the exact legal re-
quirements for your region, and observe them strictly.
• Be realistic when assessing your own skills and capa-
bilities; don’t over-estimate what you can do.
• If you notice any sign of a problem or interference, land
your model immediately, or cease operations.
• Static charge hazard!
In extremely dry air (in mountainous terrain and on
steep slopes close to weather fronts) static charges
may develop in the transmitter and / or the pilot. Such a
charge may be dissipated by a static spark which could

MULTIPLEX
damage the transmitter or cause interference, and
might even endanger the pilot. The same effects
may occur when an electrical storm is building up.
• Counter-measures:
Cease operations as quickly as possible, walk a
little way down the mountain in order to reach a
less exposed point, and never fly in a thunder-
storm or in the vicinity of such conditions.
• Keep well clear of mobile telephones!
As a basic rule we recommend that you switch off
mobile telephones and any other device which
could affect the pilot’s concentration.
• The SMART SX is protected against interference
from electro-magnetic fields, such as those gen-
erated by mobile telephones. The system far ex-
ceeds the legal requirements regarding inter-
ference rejection. However, the rapid develop-
ment in mobile radio, and the enormous range of
devices now in use, do represent a residual risk
which is difficult to assess. For safety’s sake we
therefore recommend that you always keep at
least two metres away from any mobile telephone
which is switched on.
• Antenna Separating Distance
This product contains a radio transmitter with
wireless technology which has been tested and
found to be compliant with applicable regulations
governing a radio transmitter in the 2.400GHz to
2.4835GHz frequency range.
When operating your Smart SX transmitter,
please be sure to maintain a separation distance
of at least 5cm between your body (excluding fin-
gers, hands, wrists, ankles and feet) and the an-
tenna to meet RF exposure safety requirements
as determined in the FCC regulations.

7.3 Transmitter aerial
The transmitter is fitted with an aerial exploiting the
new, patented IOAT tech-nology. The integral aerial
exhibits a radiation pattern which is ideal for the user,
and completely new in the sphere of RC system
transmitters: all the radiated power is effectively con-
centrated in the flight sector. The 2.4 GHz aerial inte-
grated into the
transmitter case
is always ori-
ented in the
ideal direction,
doubling the
signal density
over the radio
link to the mod-
el. In conjunc-
tion with the
optimised transmitting direction this aerial system
provides a significant improvement in transmission
security: effective range is far beyond the limits of
vision.
7.4 Inserting dry / rechargeable cells
The SMART SX transmitter is powered by three AA-
size dry cells; one set of cells is included in the set.
Open the battery compartment on the back of the
transmitter, and insert the dry cells as shown in the
illustration on page 7. Close the battery compartment
again. Remove the cells from the transmitter if you
know you will not use it for a long period, e.g. during
the Winter break.
Note:
It is essential to fit the batteries with correct polarity.
The negative terminal of each cell must mate with the
spring contact. Reversed polarity may ruin the trans-
mitter and / or the cells.
It is also possible to use three rechargeable cells in-
stead of the dry cells. However, these cells must al-
ways be recharged outside the transmitter, as no
charge socket is present. Be sure to use a suitable
battery charger.
7.5 Voltage monitor / operating times
The SMART SX transmitter features a permanent
warning function which alerts the user to low battery
voltage. When the dry or rechargeable cells are al-
most flat, you will hear an audible warning, and the
LED will flash red instead of yellow. If this should
happen, land the model or cease operations without
delay, and fit new or fully charged cells.
Thanks to the low energy requirement typical of 2.4 GHz
equipment, the transmitter operates for the long period of
up to 25 hours with three AA dry cells.
7.6 Binding
The first time you make the connection between transmitter
and receiver the two components must be ‘bound’. For
safety’s sake remove the propeller before doing this. When
binding is complete, the receiving system immediately
starts operating. First secure the model carefully so that no
damage can result if the propeller should start turning. If
you are unsure, for safety’s sake remove the propeller first.
• Prepare the transmitter for binding
Switch the transmitter on
with the multi-function but-
ton pressed in, and then re-
lease the button again. The
Status LED flashes yellow
at a high rate.
• Prepare the receiver for binding
Switch the receiver on with
the SET button pressed in.
The LED on the receiver
now also flashes yellow at a
high rate.
Place the transmitter and re-
ceiver close to each other.
Transmitter power is greatly reduced for the binding pro-
cess; the distance between the two units may need to be
20 cm or less. As soon as the transmitter and receiver have
“found” each other, the flashing rhythm on both compo-
nents changes to a slow rate. Any servos connected to the
receiver will now follow the movement of the corresponding
sticks.
The binding information is stored permanently in the re-
ceiver, i.e. the binding procedure only needs to be carried
out once.
If you are using an ID receiver, you will hear an audible
signal when binding is complete, and the transmitter auto-
matically loads the appropriate settings. This means that
you do not need to adjust settings 7.7 to 7.11 every time.
7.7 Channel assignment
The channel assignment of the SMART SX transmitter is
fixed; the sequence is as follows:
Channel 1: Aileron 1
Channel 2: Elevator
Channel 3: Rudder
Channel 4: Throttle
Channel 5: Aileron 2
LED (Corona) flashes red

Channel 6: AUX auxiliary function (min. six-
channel receiver required)
Connect the individual servos to the receiver in the
sequence shown above.
7.8 Mode switching
Basically there are four methods of assigning the
control functions aileron, elevator, rudder and throttle
to the two dual-axis sticks of the SMART SX transmit-
ter. Which of these options is used varies according to
the personal preference and habits of the model pilot.
The stick modes are defined as follows:
Mode 1: Right stick Throttle vertical
Aileron horizontal
Left stick Elevator vertical
Rudder horizontal
Mode 2: Right stick Elevator vertical
Aileron horizontal
Left stick Throttle vertical
Rudder horizontal
Mode 3: Right stick Throttle vertical

The SMART SX transmitter is available in two ver-
sions, each offering two stick modes. When you pur-
chase your set you must decide on one of the com-
binations, which is determined by the non self-cent-
ring throttle function.
• SMART SX M-LINK Mode 1 + 3 (# 1 5300)
• SMART SX M-LINK Mode 2 + 4 (# 1 5301)
The stick mode can be changed within the selected
combination. The first set (# 1 5300) can be switched
between Mode 1 and 3. The second set (# 1 5301)
can be switched between Mode 2 and 4.
If you wish to change the stick mode, please use this
procedure:
Locate the stick with two self-centring planes (no throttle
function), and move it to the top right corner, then press the
multi-function button for a period of three seconds: you will
now hear an audible signal; the number of beeps indicates
the new stick mode. It is only possible to swap rudder and
aileron, as shown above, since the throttle function and the
elevator are permanently
assigned, depending on the
set you have purchased. The
setting is stored permanently
for each model.
7.9 Servo reverse
The direction of servo rotation can be changed for the three
control surface functions (= all except throttle). If any con-
trol surface operates in the wrong direction, it is a simple
matter to reverse the direction of operation for that function.
Locate the stick for the control
function you wish to reverse,
move it to one end-point, and
hold the multi-function button
pressed in for a period of three
seconds, i.e. until the servo
switches to the opposite end-point. It will now respond in
the desired direction. Servo reverse is not necessary for the
throttle function, as the system always controls a speed
controller the “right way round”. The setting is stored per-
manently for each model.
7.10 Activating / disabling the throttle function
Regardless of the throttle stick position, the throttle channel
is initially disabled when the transmitter is first switched on:
your model’s motor remains off. To control the motor in
your model you must first unlock and activate the throttle
channel. You can also disable the throttle again after the
landing.
To activate the throttle function you must press the throttle
stick button once briefly, and move the throttle stick fully
back to the “Off” position. You will a rising signal.
To disable the throttle function, press the throttle stick but-
ton again. You will hear a rising signal, and the motor is
switched off until the throttle channel is re-activated.

7.11 Trims
The transmitter features digital trims for the three con-
trol surface functions. The trims are used to fine-tune
the centre position of the servos. When you adjust the
trims, you will hear a beep for every increment. For
clarity you will hear different double-beeps at the cen-
tre position and both end-points. No trim is provided
for the throttle function, as modern speed controllers
for electric power systems adjust themselves auto-
matically to the throttle stick’s travel. The trim setting
is stored permanently for each model.
7.12 Dual-Rate
In the case of model aircraft it can be useful to reduce
the control surface travels when the sticks are at full
deflection, e.g. when the model is flying at high speed.
At other times - such as when flying aerobatics - full
control surface travels are required. The Dual Rate
function provides a means of switching between full
and reduced control surface travels in flight (the throt-
tle function is not affected by the Dual Rate setting).
Press the stick which is assigned to the elevator func-
tion to switch Dual Rate on or off; elevator aileron and
rudder are affected simultaneously.
An audible signal con-
firms the current status:
a brief beep indicates
reduced servo travel, a
long beep indicates
normal servo travel. The
setting is stored perma-
nently and separately for each model.
7.13 Fail-Safe
The receiver features a Fail-Safe function. If inter-
ference occurs, preventing the receiver picking up a
valid M-LINK signal, the servos move to the pre-
viously programmed positions. In the case of a model
aeroplane this usually means centred control sur-
faces, with the motor
switched off. This signifi-
cantly enhances safety
when flying a model.
Move the transmitter con-
trols to the point where the
servos take up the desired
fail-safe positions. When you are satisfied, press the
SET button on the receiver: This action permanently
stores the Fail-Safe positions in the receiver. However
you can overwrite the settings at any time by setting
new positions and pressing the button again.
7.14 Auxiliary (AUX) channel
The SMART SX features one switched channel (=
servo channel 6). This option can be used when an
M-LINK receiver with six or more channels is used.
The trim lever adjacent to the throttle stick controls the
switched function.
This function can be used to switch working systems on
and off, such as a model’s lighting system, retrac-table
undercarriage, etc.
7.15 Range checking
Before launching a model you should always check the
range of the radio control system. Regular range checks
are very important - even when using a 2.4 GHz system - to
ensure that the RC system continues to work properly, and
to allow you to detect problems in good time.
To carry out a range check, switch the transmitter on, then
immediately press the multi-function button for a period of
two seconds, i.e. until the
Status LED glows constantly.
The transmitter now emits an
audible warning signal every
ten seconds to alert you to
the fact that it is in range-
check mode, and is only
transmitting at low power.
In this state the model control system must continue to
work up to a range of about fifty metres. If, and only if, this
is the case, the system will operate at full range - beyond
the limits of vision - when the transmitter is in normal oper-
ating mode. Switch the transmitter off to disable range
check mode; when you switch on again, the system will be
ready for normal use.
7.16 Model memory (ID)
The set is supplied complete
with a compact 2.4 GHz M-LINK
receiver with the UNI connector
system, whose small case and
in-line servo sockets make it
ideal for use in relatively small
models. However, the outstand-

ing feature of this intelligent receiver is its ID (model
identification) capability.
This feature enables the SMART SX transmitter to
recognise your model, and switch to the correspond-
ing model memory. This eliminates the constant re-
quirement to alter servo directions and adjust trim
settings, which is typical of beginners’ transmitters. If
you possess several models fitted with ID receivers,
and switch to a different model, you simply need to
switch the transmitter off and then on again. As soon
as you hear the audible ID detect signal, your model
is ready to fly. The settings for compatible MULTI-
PLEX RTF and RR+ models are already programmed
into the transmitter when you purchase it, i.e. you do
not have to carry out any adjustments at all for these
models.
However, it is also possible to overwrite or fine-tune
the model data sets at the transmitter, which means
that an ID receiver can be used in any model.
Other M-LINK receivers (light or telemetry) can also
be operated in conjunction with the SMART SX
transmitter. If you use a non-ID receiver, the SMART
SX remains at the standard model memory “0” when it
is switched on, and the audible ID detect signal is
disabled. Here again all adjustment facilities are
available, and the settings are stored automatically
and permanently.
All compatible MULTIPLEX ELAPOR® RTF and RR+
models are programmed into the transmitter at the
factory. The following receiver / IDs are available:
The receiver supplied in the set with the code ‘ID 1’ (#
5 5822) activates model memory 1 in the transmitter,
to which no model is assigned. This ID code is free,
i.e. any model can be operated with this receiver, and
the user has to program model memory 1 in the
transmitter and set it up himself.
The receiver with the code ‘ID 2’ (# 5 5823) activates
model memory 2 in the transmitter, to which the mod-
el ‘Easy Star II’ is assigned.
The receiver with the code ‘ID 3’ (# 5 5824) activates model
memory 3 in the transmitter, to which the model ‘Easy Glid-
er’ is assigned.
The receiver with the code ‘ID 5’ (# 5 5826) activates model
memory 5 in the transmitter, to which the model ‘Razzor’ is
assigned.
The receiver with the code ‘ID 6’ (# 5 5827) activates model
memory 6 in the transmitter, to which the model ‘FunCop-
ter’ is assigned.
The receivers with the codes ‘ID 21’ (# 5 5828) and ‘ID 22’
(# 5 5829) activate model memories 21 and 22 in the trans-
mitter respectively, to which no models are assigned; they
are freely available, like the receiver with ‘ID 1’.

7.17 Installing the receiver in the model
If you intend to fly a MULTIPLEX RTF or RR+ model,
the receiver is installed in the correct manner as
standard. If you wish to fly a different model, you must
install an M-LINK receiver as described in the corre-
sponding MULTIPLEX operating instructions. Please
pay particular attention to the aerial deployment:
• Do not shorten or extend the aerial or its feed
cable! If you need a longer or shorter aerial lead,
please contact the MULTIPLEX Service Depart-
ment, or a MULTIPLEX Service Centre.
• Install the receiver in the model in such a way that
the aerial is as far away as possible from any
conductive material.
• If your model’s fuselage is made of electrically
conductive material (e.g. carbon fibre), then the
aerial must be installed in such a way that the ac-
tive part (the final 30 mm) is located outside the
model.
• Do not deploy the aerial parallel to servo leads,
high-current cables or electrically conductive parts
(e.g. pushrods).
All other information can be found in the instructions
supplied with your receiver.
7.18 The SMART SX as Pupil transmitter
The SMART SX transmitter is prepared as standard
for use in a wireless Trainer system; the Teacher
transmitter can be any MULTIPLEX M-LINK transmit-
ter fitted with a multi-function socket. The MULTIPLEX
Trainer Stick can be plugged into this socket on the
Teacher transmitter. A SMART SX transmitter will
detect the presence of the stick, and switch automati-
cally to Pupil mode. If you are using a PROFI TX
transmitter with integral COPILOT, the same functions
can be used just as conveniently. Once again, please
refer to the instructions supplied with the systems
mentioned above for more information.

PROFI TX transmitter, with Trainer module.
7.19 Firmware Update / settings for future RR+
models
New firmware updates can be loaded into the memory of
the SMART SX transmitter. This enables you at any time to
bring the transmitter up to the latest technical standard. The
settings for future RR+ models can also be loaded into the
transmitter. You will need a USB adapter with Uni connect-
or (see Chapter 5, Accessories) to connect the SMART SX
transmitter to a PC (see Chapter 5).
The settings for future RR+
models or a firmware update is
carried out under menu control
with the help of the MPX-
Launcher PC program. This
software is available on our website (www.multiplexrc.de)
as a free download. Take a look at the site, as you may
already find that a new firmware update is available for the
SMART SX transmitter.
7.20 Installing aluminium sticks
A set of optional aluminium stick tops can be fitted to the
transmitter. These upgrade items are available in the fol-
lowing colours: black (# 7 3305) and orange (#7 3306). The
following figure shows the transmitter with black aluminium
sticks.
This is the procedure for fitting the new stick tops: the plas-
tic stick top is a simple push-fit, and can easily be with-
drawn; simultaneously twisting it eases the process. The
aluminium stick top can now be slid into place, and retained
by tightening the grubscrew on the side.

7.21 Speech output of telemetry data
You can still exploit the ad-
vantages of telemetry even if
you use a SMART SX system.
The basic requirement for this
is the use of a telemetry-
capable M-LINK 2.4 GHz re-
ceiver in the model, and - if
desired - the corresponding
MSB sensors. If you want the
telemetry values to be gener-
ated as speech output, you
need to use the special ‘Souf-
fleur’ telemetry receiver (# 4
5185): this unit picks up the
telemetry data from the mod-
el, completely independently of the transmitter, and
generates the values in spoken form in real time, as
well as vario tones and warning indicators. Please
refer to the operating instructions supplied with the
device for all further details.

9. C
ARE AND
M
AINTENANCE
The transmitter requires no special maintenance. We
strongly recommend that you have your unit checked
at regular intervals by an authorised MULTIPLEX
Service Centre. This should occur every two or three
years; more often if you use the system heavily.
Regular checks of all working systems and radio
range are mandatory in any case.
The best method of removing dust and dirt is to use a
soft paintbrush. Stubborn soiling, such as grease and
oil, can be removed with a moist cloth and - if neces-
sary - a mild household cleaning agent. On no ac-
count use powerful cleaning agents such as white
spirit or other solvents!
Avoid subjecting the transmitter to shock and pres-
sure. The transmitter should always be stored and
transported in a suitable protective container (trans-
mitter case or bag).
