Spektrum™ AirWare™ Software. Remarkably Easy to Use.
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.
Talk isn't cheap. It's Priceless.
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.
Wireless Trainer Links
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.
250 Model Memory
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
Fly Smarter with Built-in Telemetry
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
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.
DSM2 is the 2nd generation of Spektrum DSM technology and remains a premier 2.4GHz choice even today. Using the same superior wideband DSSS foundation that all Spektrum technology is based on, DSM2 consistently provides faster response and more precision than most non-DSM 2.4GHz protocols.
DSMX is a natural evolution of DSM2 technology that is the result of several years of development, optimized for pilots and combining Wideband DSSS and Frequency Agility. 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. DSMX represents the world's first wideband, frequency-agile 2.4GHz signal protocol and the most advanced spread spectrum RC technology to date.
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.
For the most part, 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. The only exception is the DXe which is DSMX-only and not compatible with DSM2 receivers.
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.
A resequencing of the data a Spektrum transmitter transmits based on the type of mixing you select. This feature helps to sync control services that are connected (such as a swash plate on a helicopter) and is used in radios that have many channels.
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.
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.

The length of the antenna is on a Spektrum receiver is set and tuned to optimize the range and performance of the receiver. We do not recommend altering the length of the antenna on any Spektrum Receiver.

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.
