The Spektrum DX8 Gen 2 2.4GHz DSMX 8 Channel Radio System takes 8-channel sophistication to new heights with features and capabilities that cannot be matched by anything else in its class. Voice alerts, 250-model memory, wireless trainer, 4 model types – you get all that and more.

Diversity Antenna
Using a combination of vertical and horizontal arrays, the diversity antenna provides superb protection against polarization blind spots, ensuring your receiver always “sees” the signal.

Programmable Voice Alerts
The DX8 lets you keep tabs on important functions without ever taking your eyes off what you’re flying. You can program voice alerts 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 DX8 will tell you.

Wireless Trainer Link
This exclusive Spetkrum technology gives DX8 users the ability to wirelessly link up with other Spektrum transmitters and specially-equipped Spektrum FPV headsets. Once bound to another transmitter or component, ModelMatch™ technology will allow the DX8 to re-link without having to go through the bind process again. With Wireless Trainer Link, you could:

  • Wirelessly ''buddy box'' with another DSM2®/DSMX® transmitter when teaching someone to fly.
  • Assign gimbal functions to a 2nd ‘camera’ transmitter when flying a camera drone so you can focus on avoiding obstacles and maintaining visual contact while someone else lines up the shot.
  • Link with specially-equipped Spektrum FPV headsets to wirelessly control head tracking and remotely change video frequencies on the fly.

250-Model Memory
The enormous capacity of the DX8'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 DX8 uses the same AirWare™ software as many other Spektrum transmitters, you can share model setups across platforms with almost any Spektrum pilot.

Fly Smarter with Built-In Telemetry
The built-in telemetry feature gives you real-time information on things like your model's battery voltage, signal quality, engine or motor temperature, airspeed, altitude and more.* Using the voice alert system, you can program the DX8 to tell you when specific telemetry values reach or exceed limits you define. You can also have it 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 DX8 can be set up to record the data to its SD card. *Requires a Spektrum telemetry module and telemetry sensors, sold separately.

Programming Features
The DX8 comes with an impressive list of programming features that rivals that of much more expensive transmitters.

Spektrum RC DX8 G2 2.4GHz DSMX 8 Channel Radio System (Transmitter Only)
I had 40 flights on this Transmitter then I had a “system fault” from a corrupt file. It caused me to lose all control and a plane. I contacted spectrum, they had nothing to say about my plane but said to do a forced reset, updated the firmware (again) then validate all models. Did that and haven’t had a problem in 20 flights, fingers crossed. I love this transmitter but I won’t trust it for a while. Had spectrum products for years and never had a problem like this. Just my luck I guess. I would still recommend this radio.

Spektrum RC DX8 G2 2.4GHz DSMX 8 Channel Radio System (Transmitter Only)
It’s more technical than my old dx7, but after scrolling through the menu for some time and setting up a couple planes, it’s starting to make sense. The manual is of little help, you just have to play with it. I like the voice and tones, and have no trouble hearing them. I wish there was a written menu available for the voice commands. Scrolling through hundreds of words trying to find one that will work is difficult. All in all its a great radio and after several flights has performed flawlessly.

Spektrum RC DX8 G2 2.4GHz DSMX 8 Channel Radio System (Transmitter Only)
This is my first real transmitter. I went thru the comparison chart on the Specktrum website of each model to help me, looking up and researching each feature to understand. Maybe it was a little too much for my budget, but... The voice alters, as apposed to beeps, because then I don't have to take my eyes of the plane to know what's up. There where more adjustments and mixes for sailplanes, which I see myself getting into. It had a recharge TX battery. I didn't want to fuse with always buying batteries. The difference between the DX6 & 8 was getting close to the price of battery and charger separately. There are many in-depth videos on YouTub. There are pre-configured planes you can download from their website, very easy with a SD card. I used a small, old 2G card without problems. They didn't have my new planes, but not needed when Spektrum's Binding works so well for my UMX Sport Cub S2 & UMX Radian. Cheers!

A Solid Piece Of Equipment Right Here. I've Owned The DX6i For 10yrs Binding To Every Aircraft I've Ever Owned. The Need For The DX8 Was To Start All Over With The Best Technology Out Here.

Spektrum RC DX8 G2 2.4GHz DSMX 8 Channel Radio System (Transmitter Only)
So far so good. Wanted this for a while to upgrade from my Dx6e. Extra channels for using the SAFE select option my my 6 channel BNF planes. Voice alerts, rubberized grip, included Li-ion battery and charger. Best of all FT had it in stock when even straight from Horizon would have taken a few months. It came in time to be used with my new E-Flite A-10.

Spektrum RC DX8 G2 2.4GHz DSMX 8 Channel Radio System (Transmitter Only)
This technology is definitely the hardest thing to understand.
I’m an old school flyer and they’ve made it too difficult for guys like me.
I spent the money and can’t fly my planes with confidence anymore
