The X-8N is a competition-grade radio for cars, boats and tank operations.  If you are looking for a radio that is packed with features, real-time voice telemetry and dozens of add-on expansions, then the Graupner X-8N is the radio for you.

The X-8N is powered by a 4000mAh that provides hours of operation. You are always connected with your vehicle through built-in voice telemetry capabilities that relay real-time information of main pack/receiver voltage, engine/receiver temperatures, and RF signal quality.

When used in conjunction with our GM Racing line of telemetry speed controllers, the X-8N enhances your racing experience with real-time motor information like RPM, speed, and current/remaining battery capacity. These parameters can be configured to inform you of important changes to your system, such as low battery or high temperatures that require immediate attention.

Ease-of-use is further enhanced by allowing you to configure directly from the radio all our telemetry and product settings (such as GPS, servos and ESCs).  Programming cards and computer links are no longer needed to setup or make quick changes to the system.  Just use the X-8N wireless access features and you will be up and running in no time.

The X-8N provides a complete data log for each race, storing all critical information on the SD memory card which can be analyzed to improve your system's reliability and performance.  With free Graupner Update Studio downloads you can view your model data on the screen and oversee all aspects of your time on the track!  If you want to further enhance your X-8N radio you can add the Bluetooth Module (P/N S8351) for Android phone or tablet, allowing you, your spotters and your fans to follow a real-time overview and progression of your race.

I have been using this radio for six months or so. I really love it. The telemetry is amazing. The nitro car functions are also amazing. You can't beat the price on the receivers and servos. Very high value. The throttle trigger is adjustable. The ergonomics of the drop down steering wheel are great.

I have had a Graupner MZ-18 for quite some time now, when it came time to buy a radio for surface use it was a no brainer for me. I did however do extensive research and still kept coming back to the X8-N. The Telemetry, ease of use, look, feel this radio had it all for me. Did i mention the telemetry... I now use this for 3 different trucks and a RC Boat. Buying from GraupnerUSA ended up being the best deal with the free case which is a great addition. I really only have 1 complaint, the antenna. I know it needs to be there but I do wish all Graupner radios had it without the large aerial. Thanks guys!

Good stuff !!
This radio is on-par with any other top brand out there. The adjust-ability and functionality are superb for the price range. Download the online manual, read it and see all of the amazing things this system can do. The radio comes complete with battery, a NICE case, SD card, receiver and wiring adapters. Well done Graupner...... But wait !! Look what I found.... Graupner X-8E-4-Channel-2.4GHz-HoTT-Color-TFT-Surface-Radio The X-8E looked so good, and I am familiar with the Graupner brand, that I just recently purchased one and gave the X-8N to my son who was using the stock radios that come with most models today... He now uses only one radio system, the X-8N for the 4 RC cars that he currently has. Review on the X-8E coming soon !!

Price is very affordable compared to other high end transmitters. If you compare specs, the X8n is rite up there with the Futaba's and Airtronics, actually the latency is faster on the X8n. Coupled with the ESC, having the ability to control speed control settings from the radio is a huge plus in my book. If I had to find something I would change, that would be the grip. Would have been nice to have a foam or rubberized grip, instead of plastic. Other than that, this radio system great!

The X8-N is a big big bang for your dollar. It has a good weight to it, the steering and throttle trigger has a good feel to it. With all the options and accessories with the telemetry capabilities where can you go wrong. Get this radio in your hand and see what I'm talking about.
