From its beginnings, the people behind Spektrum technology have constantly sought new
make the RC experience simpler, safer and, most of all, more fun. The DX9 is proof positive this relentless
spirit of innovation lives. on.
While the DX9 possesses a number of class-leading features, the centerpiece is its incredibly advanced voice
alert system. In fact, with its lexicon of over 300 words, numbers and phrases, it's quite possibly the most
advanced system of its kind ever seen (or heard) in a handheld, 9-channel transmitter.
For instance, you can program the DX9 to call out what flight mode has been chosen when switching from one to
another. It can also be programmed to call out specific values for voltage, temps, or any other critical
telemetry info, on demand. If an alarm goes off, the pilot won't have to look at the display to see what's
happening. The DX9 can tell them.
The DX9 comes out of the box with English voice alerts. Other languages are available for download.
While the DX9 does have a trainer cord jack, it gives instructors the option to wirelessly "buddy box" with
another DSM2®/DSMX® transmitter. Once bound to another transmitter, ModelMatch® technology will allow the DX9
to re-link without having to go through the bind process again.
This innovative software feature will equip you for a new generation of Spektrum components that can be
programmed directly through the DX9. This, along with regular Spektrum AirWare™ software updates, will ensure
the DX9 remain as cutting-edge tomorrow as it is today.
*Available with DX9 AirWare software version 2.0 and higher.
The enormous capacity of the DX9's on-board memory means you will rarely, if ever, need to juggle models
between transmitter memory and your SD card. The model memory menu is easier to navigate too. Only memory
slots with model settings saved to them will appear. It won't be necessary to scroll through empty slots or
move models around if one is deleted.
Instead of a simple tone or vibration, the DX9 voice alert system tells you exactly what you want to
The DX9 is equipped with a built-in telemetry feature that gives you real-time information on things like
your model's battery voltage, signal quality, engine or motor temperature, airspeed, altitude
Using the voice alert system, you can have the DX9 call out specific telemetry values that reach or exceed
limits you define. You can also have the DX9 call out a sequence of telemetry values on demand with the flip
of a switch. If you want to review telemetry after a flight, the DX9 can be set up to record the data to its
† DSM2 not available in EU.

The AMA (Academy of Model Aeronautics) has certified its use at all AMA fields and events when used as per the manufacturer's instructions. In fact, most event directors welcome Spektrum, as it eliminates the issues of frequency management.
DSM or Digital Spectrum Modulation is Spektrum's proprietary method of implementing 2.4GHz spread spectrum technology for the R/C industry. DSM divides the 2.4GHz band into 80 individual channels (frequencies) and incorporates direct sequence spread spectrum with an embedded GUID (Globally Unique Identifier) code. DSM has been painstakingly optimized by our engineers for RC surface and aircraft use, offering the most robust RF link in the industry.
A Natural Evolution
Spektrum launched the 2.4GHz RC revolution. Since then millions of hobbyists the world over have come to embrace 2.4GHz technology as the way to race and fly. Spektrum leads the way yet again with DSMX™; the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.
DSMX is a natural evolution of DSM2™ technology that is the result of several years of development. It builds on what has come before and takes DSM to the next level of robustness, reliability and efficiency without leaving current DSM2 users behind.
What DSMX™ adds to the tried and true wideband technology of DSM2™ is the extra interference protection and faster reconnection times of frequency agility. But DSMX isn't just another frequency hopping system. It’s wideband agile.
DSMX frequency shifts are coordinated using the most advanced FHSS algorithm ever seen in an RC application. Unlike other FHSS transmitters that all hop in the same fixed patterns, every DSMX transmitter has its own unique frequency shift pattern calculated using its GUID (Globally Unique Identifier). And each pattern uses just 23 channels in the 2.4GHz spectrum.
By adding the agility of unique frequency shifts to the superior interference resistance of a wideband signal, and limiting those shifts to a smaller portion of the 2.4 band, DSMX transmitters provide on-channel interference protection that is simply second to none. The result is quicker reconnection times and superb response in the noisiest 2.4GHz environment.
The foundation DSMX is built on is the same foundation as DSM2™ - the superior on-channel interference resistance and coding gain of wideband DSSS. Compared to the wideband signal of a DSM2 or DSMX™ system, the narrow-band signal of other 2.4 transmitters is more likely to suffer crucial data loss in the event of on-channel interference. Think of wideband 2.4 as a river and narrow-band 2.4 as a stream. It takes much more interference to stop a river than it does to stop a stream.
The big reason wideband is so robust is coding gain. Essentially what this means is that the unique coding in a DSM2 or DSMX wideband signal allows it to be heard well above the noise of surrounding 2.4GHz signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrow-band competition using the same amount of power.
Yes. DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both.
Yes, but DSM2 users who rarely, if ever, fly in big events or other "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need. The difference DSMX makes is only apparent when hundreds of 2.4GHz systems are in use at once. To see if your transmitter is eligible for the DSMX add-on, please visit horizonhobby.com, click on the “radios” tab, and select “DSMX addons” for more details.
Spektrum AirWare™ software was developed exclusively by Spektrum from the ground up. This software includes all the programming functions an expert pilot could want, but you don't have to be an expert to use them. It also brings several unique benefits to Spektrum programmable transmitters that simply aren't available on other systems.
The Spektrum™ Data Interface (SDI) is designed for use with standard SD memory cards and adds a whole new level of flexibility and ease-of-use. With the SDI, you will be able to:
Share setups with others who use the same radio as yours or transfer setups from your SD card to your PC and attach them to an e-mail. This makes it easy to gain from the experience of others or help others succeed. With the SDI, memory for thousands of models could be stored on the SD card or transferred to a PC hard drive for backup. And you can stay up to date with SDI, you won't have to send your Spektrum radio into a service center to get the latest Spektrum AirWare™ enhancements. You can download them onto your SD card and upload them to the transmitter yourself.
Yes. DSMX will provide users with these and the many other exclusive Spektrum advantages they already enjoy with DSM2.
The Spektrum™ X-Plus™ 8 module lets you add 8 fully proportional channels to specially equipped Spektrum transmitters and receivers with 10 or more proportional channels. Just plug it into the X-Plus port of a compatible receiver. It is ideal for scale modelers who like to push realism to the extreme with working accessories and lights in addition to the regular control functions. The DX10t and DX18 offer X-Plus.
Spektrum park flyer receivers are designed for small models up to 2 pounds. Spektrum full range receivers are designed to handle any normal RC conditions. You should have no problem maintaining control as long as you maintain direct line-of-sight with your model. If you try to fly behind a group of trees or otherwise obstruct your direct line-of-sight, you could be susceptible to losing your control link.
DX9 Product Tips
If your old radio is a DX7s or DX8 then the model files are NOT compatible. Only the DX6, DX9, DX10t, DX18, and DX18QQ can share model files. Keep in mind that only channels and features which exist in both radios will function.
Any Spektrum/JR DSM2/DSMX receiver or DSM2/DSMX Bind-n-Fly equipped aircraft are compatible. DSM receivers such as the AR6000/BR6000 are NOT compatible.
Any Spektrum/JR DSM2/DSMX transmitter can be bound to the DX9 for use as a wireless buddy box.
