DSX9

Get To Know "JR DSX9"

JR seems to have found a way of making the best even better! With the new JR DSX9, users will find that the well designed system programming is easy to learn and use. Even without the manual it’s easy to navigate the system menus and perform quite a bit of the programming available, and after a little time with the manual you’ll be able to completely access and utilize all of the robust features of this top of the line radio. In fact, owners of the radios will be able to transfer their model’s programming data directly from their old radio to the new transmitter.

THE DSX9 and X9303 SIMILARITIES & DIFFERENCES
JR DSX9 is almost the same with X9303 2.4 in terms of HEIGHT, WIDTH and WEIGHT. Both are DSM/DSM2 compatible, with R921 DSM2 receiver included. It has a 7-point throttle and pitch curves, five CCPM mixes (2s 180, 3s 120, 3s 140, 3s 90, 4s 90), pre-programmed cyclic-to-throttle mixes, pre-programmed Governor mixes, 6 progammable mixers (2 multi-point style), and 3-axis dual rate and expo.

JR quality, unmatched product support, programming sophistication you’ll probably never outgrow, along with the all-important advantages of Spektrum 2.4GHz convenience and security. It’s the most unique advanced radio control system ever offered—the system the world’s been waiting for.

Both transmitters are available with 9-channel R921 receivers and no servos, but JR X9303 2.4 have a complete systems including four, 72 oz/in DS821 digital servos, while JR DSX9 2.4 transmitters have a complete systems including four JR 539 high powered ballrace servos.

The bulletproof R921 2.4 DSM2 DuaLink receiver. In addition, all existing Spektrum brand receivers are also compatible with both transmitters. Not only can data for 30 models of all types be programmed into the transmitter, but owners of conventional radios will be able to transfer their models’ programming data directly to their new 2.4 transmitters.

This new technology will change the way you fly your planes. Not only are frequency conflicts completely eliminated with this new system, but with DSM2 ModelMatch Technology it will make it impossible for you to “accidentally” try to fly your plane with the incorrect model selected in the radio.

DSM2 TECHNOLOGY

Above and beyond the basic features of DSM, there has been a technological breakthrough for both air and surface applications thanks to Spektrum. An updated version of DSM technology referred to as DSM2 (second generation protocol) makes it possible to fly any size model with the convenience, safety, and peace of mind of Spektrum. With DSM2, the total latency of your radio system has been greatly reduced, while the bit-rate has been increased. When combined, these improvements provide hobbyists with a faster and more locked-in feeling when compared to traditional 27MHz, 72MHz, or 75MHz radio systems. DSM2 also provided a new opportunity when separating the two receivers. By providing superior path diversity, the DSM2 receiver can now see a broader RF environment.

Specifications
* Number of Channels: 9
* Band: 2.4 Ghz
* Receiver: R921 (JRPR921)
* Programming Features: Aircraft, Heli, & Sailplane
* Model Memory: 30
* Modes: MODE 1 TX & Mode 2 TX (Note that the Tx is Mode changeable via the software, but stick positions are different in Mode 1 vs Mode 2)
* Transmitter (Tx) Type: AA Batteries

JR’s first DSM2 radio is based on the incredible JR PCM9X II which utilizes the old 35MHz or 40MHz or 72MHz frequencies. People who have the old JR PCM9X II owners  can easily upgrade to JR DSX9 by simply buying an upgraded module.

The DSX9 is fully compatible with Spektrum’s receivers and offer exception security and puts an end to frequency clashes.

Take a look at the picture below.  It almost doesn’t have any difference except for the model number.  For the record, JR X9303 is the US equivalent of DSX9 in Asia

THE PARTS
1 - Multi-function button switch can be used as a timer or snap roll button. It is also assignable to numerous

2-position tasks such as retracts - Touch once for gear up, touch again for gear down. It can also be used as the trainer button or it makes a great throttle kill switch.

2 - Dual side levers offer handy access and flexibility when they’re used with a program mix and/or assigned to virtually any function you choose. There is one on either side of the transmitter case, easily accessible by your index fingers.

3 - Mechanical throttle trim - I like this feature over a digital trim as it allows quicker response and is easier to tell the position of your idle setting. Once on the ground you can quickly slide it all the way down to kill the engine

4 - Largest-in-its-class LCD enhances comprehension and accommodates more information at a higher resolution.

5 - JR’s exclusive 3+1 trim system combines the precision of three digital flight-axis trims with an analog throttle trim for immediate visual and tactile reference to idle position. In addition, as you adjust the trim on each control the system responds with a changing tone so that you can “hear” where your trim is set.

6 - JR’s innovative, exclusive Rolling Selector System is at the heart of the transmitter’s programming operation. You’ll roll to scroll, press to select, roll to adjust and press to store.

7 - Dual rate switches may be used as designated. Triple rates are available as components of the transmitter’s flight modes, when they’re activated.

8 - The transmitter’s flexible and versatile programming requires tremendous memory and processing power. Not surprisingly, the transmitter employs an advanced, powerful microprocessor with nearly six times the RAM and ROM of previous generation systems.

9 - The transmitter features a flap trim switch right on the face of the panel to make minor flap adjustments in flight, as well as a trim switch for the Aux channel located on the upper right of the radio.

The radio is easy to program and yet is versatile enough to meet the needs of even the most demanding

The JR DSX9 is easy to program and yet it is versatile enough to meet the needs of even the most demanding RC flyer.

JR has hit a home run by taking their industry leading radio and adding the benefits of the new 2.4Ghz Spread Spectrum technology to it, making this radio the gold standard in 9 channel Spread Spectrum RC systems.
