The biggest breakthrough in RC technology since digital proportional control is here at last. Introducing the new full range revolutionary 2.4GHz digital spread spectrum Radio System based on popular JR 9303 radio. Not only can data for 30 models of all types be programmed into your X9303 2.4, owners of conventional XP9303s will be able to transfer their models' programming data directly to their new X9303 2.4 transmitters.

The radio and receiver requires no crystal.

Features:
- DSM/DSM2, Compatible with all Spektrum™ Brand Aircraft Receivers
- R921 DSM2 Receiver Included
- Flight Modes (3 Airplane, 5 Sailplane, 6 Helicopter)
- 6 Programmable Mixers (2 multi-point style)
- 3-axis dual rate & expo and 3-position flap
- Gyro System (In-flight selection of 3 gains for up to 2 gyros)
- Trim system offers presets for ail/ele/rud/flaps/flaperon for each mode (Sailplane)
- Launch/Land Flight mode over ride system (Sailplane)

As the foundation for an advanced, full-range, spread spectrum radio, it's hard to imagine a more ideal candidate than JR's XP9303. A breakthrough in versatility and flexibility when it was introduced, the 9-channel, 30-model memory, 3-model type 9303 is an enormously popular radio upgrade for fliers whose skills have outgrown sport-class equipment. With software shaped by the input of top airplane, sailplane and helicopter pilots, plus its exclusive rolling ease and speed of programming, the 9303 remains the standard by which all 9-channel radios are judged. And now, with the added convenience and security of Spektrum DSM2 2.4GHz technology, the newly-designated X9303 2.4 is destined to be a breakthrough once more.

DSM2 - Security and Speed
Unlike most first-of-its-kind innovations, DSM2TM 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 1024 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.

R921 - Spectacular Signal Clarity
R921 dual receiver that comes with the 9303 2.4 is key to the system's incredibly robust RF link. Comprised of a compact main receiver that is linked to an even smaller satellite receiver by a 6" lead, the R921 acts as a pair of extremely sharp RF "eyes" that each take in a slightly different view of the signal environment. Information from both receivers is then processed by patent-pending Spektrum software that takes information from each receiver and combines it to form the most vivid "picture" of an RF signal than has ever been possible in RC before.

ModelMatch - Extra Safety and Precision
DSM2 and the R921 aren't the 9303 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 9303 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 X9303 2.4. Consequently, there's no added processing time. What's more, Spektrum engineers have incorporated technology that permits owners of conventional XP9303 radios to transfer all of their model programming data from their transmitters directly to their new X9303 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 X9303 2.4, and it's the most unique advanced radio control system ever offered. The system the world has been waiting for.
