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.

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.
