Product Description

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.
