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 it's incredibly advanced voice
alert system. In fact, with it's 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
