JR's phenomenal 12X is the ultimate combination of pro-class performance, security, convenience and quality. As a product of inspired collaboration between JR and Spektrum engineers, the integrated 12X 2.4 and module-based 12X MV represent a true breakthrough in pro-class radio control. So in addition to flying with the proven security and convenience of Spektrum™ 2.4GHz DSM® technology, you can expect to be flying with the kind of innovative, no-nonsense features you expect from JR features devoted solely to the experience of flying with optimized control of your models.

Ultra-fast 2.4GHz DSM2 Control Response with Refined 2048 Resolution
The extreme low latency of the 12X a result of JR/Spektrum cooperation and ingenuity--delivers an astonishing sense of connection with your model. It's a feature that prompted perennial World Championship competitor Quique Somenzini to declare the prototype "unbelievable, amazing" after only one flight. Also, thanks to another 12X breakthrough, all 12 channels respond to commands with identical speed and perfect synchronization for unprecedented control precision. Then, to top it off, the instantaneous response of the 12X is complemented by the accuracy of JR's refined 2048 resolution.

Exclusive ModelMatch Technology
Prevents "wrong model syndrome" plus a 50-model memory. Here's how ModelMatch works: If you're operating on 2.4GHz and your transmitter doesn't "recognize" your model as the selected model, when your airborne system is turned on, there'll be absolutely no control response. You'll be alerted that something's wrong and a costly crash may be averted. Also, the 12X's included PC Data Transfer System permits you to upload an unlimited number of model setups from your transmitter to your computer, then access and download any 50 of them to your 12X transmitter's model memory for use at the field.

Unmatched JR Quality in Every Detail
From its exclusive, durable, precision-cast magnesium transmitter housing to its ultra-legible, high-resolution backlit display, everything about your 12X speaks of the kind of quality that's a benchmark of JR equipment. The ultra-smooth, quad-bearing stick assemblies, proven rolling selector data input, accessible shoulder mounted momentary contact switches, and details like the custom-naming capability for flight modes all contribute to the unmistakable feeling that you're flying with the very best, most intelligently conceived pro-class equipment that's ever been introduced.

DSM2 - Security and Speed
Unlike most first-of-its-kind innovations, DSM2 is not an unproven concept. It is based on the exact same Spektrum 2.4GHz DSM® (Digital Spectrum Modulation) that RC car racers as well as micro electric and parkflyer modelers have been enjoying for at least two years now. Like DSM, DSM2 provides an impenetrable radio link that's immune to every known type of RC interference. And because it operates at 2048 bit resolution, it provides the kind of locked-in response that will have you feeling more connected to your model than ever before. The big difference with DSM2 is that, in addition to absolute precision and complete freedom from interference, it processes its signal faster than any high-end 72MHz PCM system. In fact, many of the pilots who have tested the DX7 describe DSM2's response time as almost telekinetic. You'll feel more connected with your model than every before.

ModelMatch - Extra Safety and Precision
DSM2 and the R1221 aren't the 12X 2.4's only marvels. Spektrum engineers have come up with patent-pending innovations that you'll wonder how you ever lived without-ModelMatchTM. ModelMatch puts an end to the "wrong model" syndrome. Almost everyone that flies RC has, at one time or another, crashed, or seen someone crash, because they neglected to verify the model name on the transmitter display in their preflight check. With the 12X 2.4's a unique code is embedded in the signal so that if the wrong model's name is on the screen, the model's controls simply won't respond.

A Completely Integrated Radio System
Instead of settling for a 2.4GHz module adaptation to accomplish spread spectrum capability, JR has incorporated DSM2 as an integral feature of the 12X 2.4. Consequently, there's no added processing time. What's more, Spektrum engineers have incorporated technology that permits owners of conventional JR radios to transfer all of their model programming data from their transmitters directly to their new 12X 2.4 transmitters!

The Bottom Line
JR quality, unmatched Horizon Hobby product support, programming sophistication you'll probably never outgrow, along with the all-important advantages of Spektrum 2.4GHz convenience and security. That's the 12X 2.4, and it's the most unique advanced radio control system ever offered. The system the world has been waiting for.
