Multiplex Cockpit SX12

Cockpit SX 12 -channel M-LINK radio control system –the future has arrived!

Developed and built in Germany, the Multiplex Cockpit SX 12 is perfectly suited to both the forward-looking leisure pilot and those who demand a little more from their flying and their radio. Offering a full-colour TFT touch-screen of 320 x 240 pixels, pilot information is offered via symbols and large, clearly legible letters and numerals. It’s visible in sunlight, too, without backlighting, which makes it perfect for flying in all weathers. Boasting a highly intuitive programming logic that includes many self-explanatory graphics, plus super-convenient SD card management of the 200 internally stored model memories, you’ll quickly grow to love its user-friendly feature set.

Since we’re beginning to get used to our transmitters talking to us – who’d have thought it? – many R/C flyers are now looking for a radio with speech output, and in this respect the SX 12 leads the way with more than 450 words, numbers and phrases in its vocabulary. In fact, where speech is concerned it’s one of the most advanced systems of its type ever to have been incorporated in a hand-held transmitter. This, of course, keeps you aware of critical telemetry data and transmitter functions without having to take your eyes off the model. Also, when necessary, the SX 12 speaks specific sensor values to you and, moreover, if an alarm should be triggered, you don’t have to look at the screen to see what’s happened, the SX 12 just tells you. Eight telemetry sensors can be connected that measure anything from current to temperature, whilst telemetry data can also be stored in the model using the optional Flight Recorder.

Featuring a wireless trainer system the SX 12 can (in tandem with the optional Co-Pilot module) operate both as an instructor or pupil transmitter, whilst the second transmitter can be any M-LINK set with a trainer facility. Meanwhile, Selective Trainer Mode allows you to transfer full control to the trainee or, depending on the student’s skill level, individual control functions. Better still, the teacher can resume control of the model simply by moving the sticks. All in all, it’s a powerful system. Take a look at the features and functions, weigh them against the price, and decide for yourself.


Touch, Control and Fly! - Operation like a smartphone!  
This makes the COCKPIT SX 12 easy to program through its app icons. The new software SAFE-LINK in combination with further numerous new software features further evaluates the transmitter. The model assistant guides you intuitively through an ingenious touch concept with clear screens and many self-explanatory graphics. Easy-to-read TFT color display screen (even with sunlight) 3.5 ", 320x240 pixels, with automatic day / night switching. Transmitter operating time up to 24 hours possible. 
Unique in this class is the intuitive control of functions via motion sensors (position or 
rotational speed sensors). For example, for camera movements, triggering speech output, etc. 

The COCKPIT SX 12 is ergonomically outstanding!
The transmitter has a very pleasant housing size and is super light in the hand. All switches / transducers can be reached comfortably without taking the thumb off the stick. The encoder assignment is individually selectable. 
The ideal remote control for RC surface models, RC helicopters and RC-Copter. 
The COCKPIT SX 12 is 100% developed and built in Germany. Quality Made in Germany! 


The COCKPIT SX 12 is fitted with this module as standard. The unit is a gyro / position sensor, which can be used either to control servos directly, or optionally to switch various functions. It is also possible to use it as input in servo mixers and transmitter control mixers. (Please read the instruction manual below for further explanation of this fantastic feature)

color touch screen display, transflective color display 3.5 ", 320x240 pixels, Touchscreen with meaningful symbols and large, easy-to-read digits / letters. Can be read with sunlight without background lighting: ideal for model sports. Extremely energy saving in outdoor operation due to automatic day / night switching. Transmitter operating time up to 24 hours possible. Disable display inhibit. 

Simple and extensive programming possibilities via new model assistant 

Intuitive operation thanks to a sophisticated touch concept with clear screens and many self-explanatory graphics. A comfortable model assistant with a wide range of options for adjusting the values ??via the touch screen. Easy adjustment via slider, direct input of values ??with alphanumeric keyboard, +/- and buttons for the fine adjustment ensure the simplest programming of your models. 

Super comfortable model 
storage management The COCKPIT SX 12 is equipped with 200 internal model memories, the model memory is stored on the internal SD card in the .xml format. A comfortable model memory management on the PC via USB mass storage is therefore easily possible. 

Outstanding voice output 
With more than 450 words, numbers and phrases, it is one of the most advanced systems of its kind ever installed in a hand-held transmitter. 
The use of this system allows COCKPIT SX 12 pilots to perceive critical telemetry data and station functions, while avoiding the view from flying. The COCKPIT SX 12, if required, tells you the specific sensor and timer values. If an alarm is triggered, you do not have to look at the display to see what's going on, the COCKPIT SX 12 tells you. 

Back-channel / Telemetry 
When using a telemetry capable receiver, the current voltage of the receiver power supply is displayed on the display of the transmitter. If an adjustable minimum voltage is exceeded, an acoustic signal warns of a vacant receiver battery. Without a sensor, the connection quality (LQI) on the transmitter display can also be displayed in% values. An additional security solution! 

In addition, up to 8 telemetry data can be displayed on the display (depending on the sensors connected to the receiver, eg voltage, current, temperature, etc.) (application examples: motor temperature, drive voltage, current consumption of the drive). The storage of the telemetry data can be found in the model instead of in connection with the optional MULTIPLEX FlightRecorder (# 8 5420). The displays and the announcements of the sensor values ??are freely configurable, dynamic adjustment of the displays. 

Wireless teacher / student 
mode The COCKPIT SX 12 M-LINK can be standard as both teacher and student transmitter. All L / S-compatible M-LINK transmitters can be used as a student or teacher transmitter. The optional COPILOT module (# 4 5184) is required for the teacher operation. The COCKPIT SX 12 operates with selective L / S operation. This allows the complete transfer or, depending on the learning progress of the student, the transfer of individual control functions to the student. Only by touching the sticks the teacher can take over the model again.
