The Spektrum™ DX18 offers the most impressive suite of features ever made available in a handheld transmitter. These include 18 fully-proportional channels, voice alerts, built-in telemetry, a wireless trainer function, three model types and more.

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.

Programmable Voice Alerts
With voice alerts, you can keep tabs on important functions without ever taking your eyes off what you’re flying. They can be programmed to call out what flight mode you’ve chosen or report telemetry information on demand. If an alarm goes off, you won’t have to look at the transmitter display to see what’s happening. The transmitter will tell you.

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.

Wireless Trainer Link
The wireless trainer link gives instructors the option to wirelessly "buddy box" with another DSM2®†/DSMX® transmitter. Once bound to another transmitter, ModelMatch™ technology will allow the DX18 to re-link without having to go through the bind process again.

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

Stay up to date
Register your DX18 transmitter and receive alerts whenever a new AirWare version is available.

Programming Features
The DX18 has all the programming functions you need to fly everything from tiny collective pitch helis to competition sailplanes and giant-scale jets.

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 recite this information on demand using the programmable voice alerts. 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.

Superior Ergonomics. Made to Fit the Way You Fly.
The weight distribution and ergonomics of the DX18 have been optimized to fit the way you fly. The result is a sense of balance and comfort that perfectly complements the speed and precision of DSMX technology.

Product Bulletin: Spektrum DX18 Extreme Range Bulletin

June 15, 2015
Download PDF Version Here

Product: Spektrum DX18G2 and Spektrum DX18 Stealth Edition transmitters with Region: US-247 in the System Settings Screen.

Issue: It has come to the attention of Horizon Hobby, LLC that some DX18G2 and DX18 Stealth Edition transmitters may have a reduction in performance at extreme ranges. Horizon Hobby performed extensive testing to confirm that the reduction in range takes place at extreme ranges well outside normal flying conditions for most conventional flying.

What To Do: Spektrum DX18G2 and DX18 Stealth Edition transmitters with a green dot in the battery compartment and on the box are not affected.

For Spektrum DX18G2 and DX18 Stealth Edition transmitters that do not have a green dot in the battery compartment and on the box, follow the steps listed below to perform a full range test. If the transmitter fails the full range test, please fill out the Repair Request Form found here. After completing and submitting the Repair Request Form, Horizon Hobby will E-mail a shipping label for you to use to return the transmitter. Typical turnaround time for a repair is 7–10 business days. You will not incur any fees or charges for the repair, if it is deemed necessary.

For customers outside of North America or Europe, please contact your local distributor.

Full Range Ground Test

Equipment Needed

1. DX18G2/Stealth Edition Transmitter.

2. Any Spektrum full-range receiver with servos attached (or an electric aircraft with full range receiver installed), together with the appropriate charged battery.

3. A small non-conductive (non-metal) stand or table approximately 30 inches (76.2 centimeters) tall (to place the transmitter on when testing).

4. Smart phone with GPS device for measuring distance.


An open area that provides an uninterrupted direct line of sight for .6 miles


1. Setting Failsafe-
Failsafe will be used to determine if the signal is lost. If using an electric airplane, remove the propeller and bind the DX18G2/Stealth Edition transmitter to the full range receiver at low throttle. When bound, verify that failsafe is working by increasing the throttle position to a low RPM then turn off the transmitter. The motor should turn off indicting loss of signal.

2. If using a receiver and servo only, put the receiver in small a small cardboard box with the antenna taped verticality and the throttle servo located so that it’s easy to see. Bind the DX18G2/Stealth Edition to the full range receiver at low throttle. When bound, increase the throttle position to full throttle, then turn off the transmitter while observing the throttle servo. Verify that the throttle servo moves to the low-throttle position.

3. Place an approximately 30-inch (75 cm), non-conductive stand or table in an area that allows an unobstructed, line-of-sight view from the table to the area where the transmitter range test will be performed.4. Power on the transmitter and receiver, arm the ESC and/or confirm the throttle servo is operational. With propeller removed, increase the throttle position to a low RPM setting. If using a throttle servo only, increase the servo position to full throttle and note the location of the servo arm for later reference. At this throttle position, place the DX18G2/Stealth Edition transmitter on the table/stand.

5. Walk or drive the model/receiver 0.5 mile away from the operating transmitter. While facing the transmitter, and with an unobstructed line of sight view, with the model/receiver held at chest height, the motor should remain on at 0.5 miles. If using a receiver/servo only, the servo should remain in its noted full throttle location.

6. If at 0.5 miles the system goes into failsafe (Low throttle position), the radio should be returned to Horizon for service by following the above instructions.

Before Sending Your Transmitter to Horizon Hobby for Service

1. Export all programmed models to an SD card.

2. Remove the following items from the transmitter:
    • SD Card
    • Transmitter Battery
    • Neck Strap
    • Any Aftermarket Accessories (Cell phone mounts, gimbal sticks, etc.)

3. Carefully wrap the transmitter in bubble wrap and pack the transmitter into a strong cardboard box, ensuring the transmitter will not move around in transit. DX18 Stealth Edition Only: Do not return the DX18 Stealth Edition Transmitter Case.
