Powerful Features for the Expert Pilot

The Spektrum AirWare software that comes in the DX18 offers all the programming features an expert pilot could want. And the intuitive SimpleScroll interface makes navigating menus and changing settings as simple as "roll and click." It's almost like using a mouse.

Many Spektrum AirWare features are innovations you won't find anywhere else; innovations that make flying safer and programming easier.

  • Pro-Class Programming for Sailplanes

    In addition to extensive airplane and heli programming, the DX18 has the most impressive sailplane programming features you'll find in any handheld transmitter. Ten available flight modes, 5 wing types, 3 tail types, 2 motor types, flap delay with elevator compensation – it has it all. You even have the ability to adjust individual servo characteristics (end points, travel, center, etc.) for all 18 channels.

  • Built-In Sequencer

    Program a sequence of switch-activated events with time delays between each event. For instance, with a flip of the gear switch you could have an auxiliary channel open landing gear doors, then have the retract channel lower the landing gear, followed by the auxiliary channel closing the gear doors after the gear is extended.

  • Built-In Servo Balancer

    No more will you need a complicated network of little boxes littering your fuselage if you want to balance servos. You can precisely balance the output of swashplate servos or multiple servos on a single control surface with the transmitter using a 7-point curve mix.

  • 250-Model Memory

    The enormous capacity of the DX18'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. You won't have to scroll through empty slots or move models around if one is deleted.

    Because this DX18 uses the same software platform as the DX6 Gen 2, DX7 Gen 2, DX9 and DX18 Gen 2, you can share model setups with owners of those transmitters as well.

  • Stay Up to Date

    Register your DX18 and receive alerts whenever Spektrum Airware software updates are available.

Max Out Your Functions.

Both the DX18 and the AR9020 receiver it comes with have X-Plus channel expansion capabilities. This means you can add up to eight extra channels with an X-Plus channel expansion module (SPMXP8000 – sold separately). Just plug the module into the receiver, bind it and then assign the extra channels to any function you want.

Fly Smarter with Built-In Telemetry.

Built-in telemetry gives you real-time information on things like your model's battery voltage, signal quality, engine or motor temperature, airspeed, altitude and more. You can have the DX18 alert you whenever any of these parameters exceed limits you define. You also have the option of logging telemetry data to the transmitter’s SD card for review after the flight.

A Spektrum TM1000 telemetry module and telemetry sensors (all sold separately) are required. You will find there are Spektrum telemetry sensors for tracking just about any model function you can think of, and new ones are being added all the time.

Is Spektrum allowed at AMA flying events?

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.

What is DSM?

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.

What is the difference between DSM and DSM2

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.

What is DSMX?

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 is Frequency Agility?

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.

What is Wideband DSSS?

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.

Is DSM2™ and DSMX equipment compatible?

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.

Are DSM2 transmitters eligible for a DSMX add-on?

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, click on the “radios” tab, and select “DSMX addons” for more details.

What is Spektrum AirWare™ Software?

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.

What is the Spektrum™ Data Interface?

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.

Does DSMX have ModelMatch™ and ServoSync™?

Yes. DSMX will provide users with these and the many other exclusive Spektrum advantages they already enjoy with DSM2.

What is X-Plus™?

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.

How much range can I expect out of my radio system?

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.
