SPEKTRUM DX9 Radio System (SPMR9900)

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 a 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. 

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. 

Wireless Trainer Link 
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. 

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 CCPM swash servos or multiple servos on a single control surface using a 7-point curve mix. 

Forward Programming* 
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 remains as cutting-edge tomorrow as it is today. 

*Available with DX9 AirWare software version 2.0 and higher. 

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 and more.* 
Requires a Spektrum telemetry module and telemetry sensors, sold separately (TM1000)

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 SD card.
