Product Description
The DX8 is the most advanced 8-channel system you will find anywhere. Its next generation Spektrum AirWare software, built-in telemetry, Spektrum Data Interface and superior ergonomics will completely revolutionize how you fly. And it’s the only 8-channel that gives you these advanced capabilities plus the proven speed and precision of Spektrum 2.4GHz DSMX control.
FOUR REASONS YOU NEED A DX8
Spektrum AirWareTM SoftwareSpektrum AirWare is software developed exclusively by Spektrum from the ground up. It has all the programming functions an expert airplane or heli pilot could want, but you don’t have to be an expert to use them.Built-In TelemetryThe built-in telemetry feature on the DX8 gives you the ability to receive real-time information on things like your model’s battery voltage, signal quality, engine or motor temperature and more. And it will all appear right on the big, backlit DX8 display so you can see it at a glance.Superior ErgonomicsThe weight distribution and ergonomics of the DX8 provide a sense of balance and comfort that perfectly complements the speed and precision of its DSMX technology. You really do have to feel it to believe it. Some of the more impressive ergonomic features are those usually only available on much more expensive transmitters.Spektrum Data InterfaceWith the Spektrum Data Interface you can use a standard SD* card to share model setups with other DX8 owners, store extra model memory and stay up to date with the latest software releases.Always purchase products from a Horizon Hobby, Inc. authorized dealer to ensure authentic high-quality Spektrum product.

Lots of serious software problems
By Z8
Update: After losing another airplane to a lost link (makes 3 now), I gave up on my Spektrum and upgraded to the more feature packed Aurora 9. My Hitec Aurora 9 review is also posted on Amazon. With the included 9ch receiver and the promotional free 7ch receiver plus a third 7ch or 9ch at half price (all include triple-redundant power inputs and voltage telemetry), the radio system was about $200 less expensive than my unreliable DX8.The difference in control precision, real time responsiveness, programming features, ergonomics and controls, and speed of data entry through the huge backlit touchscreen (QWERTY) is night and day over the DX8. Finally, no more control input latency which still plagues the DX8 w/AR8000, although it is not as bad as using the DX8 with their 1024 resolution receivers. All Aurora 9 receivers have 2048 resolution with real time response, redundant Rx power inputs, and automatically send useful telemetry info, even the inexpensive 6ch Lite (11 gram) version. No more Specktrum "brownouts" (which really means 10 second blackout) which happen too frequently, especially with their more power hungry receivers like the included AR8000 + Satellite Rx + big TM1000 telemetry module, which has to be soldered-in just to pick-up voltage telemetry.I highly recommend the Aurora 9 if you are serious about RC and want a pro caliber system, or simply want to save money, time, and planes.-----Update: March 28, 2011: All four stick potentiometers no longer work properly. I wasn't sure why my models' servos were not centering properly, until the aileron channel of the DX8 got so bad that I checked the monitoring screen. The aileron channel randomly centered from 21% off from neutral to 0% after each stick movement. It also produced stepped servo movement. The other channels had the same anomalies, but not as bad. Doing some web research reveals that this is very common and Horizon is generally unable to fix it, as they replace old cheap hardware with new cheap hardware that quickly (or in some cases immediately) develops the same issues. This radio has been a nightmare - avoid at any cost.-----Ok, this is a hard review because I love the improved trim resolution and control compared to my many older DX radios. But clearly, one of two things is true:(1) Spektrum doesn't test much before release(2) Spektrum released an extremely hazardous product on purposeI hope its (1) but think it is (2). This thing has more software errors than Windows, it is simply horrible. There are lots of videos on youtube showing model crashes from mixing errors, switch problems, timer time bombs than erroneous enter full nose down at expiration (almost looks like a like a kid software programmer left a Trojan Horse on purpose, see:[...]), and lost radio links.Examples:- Rudder trim is reversed for one of my mixes. Rudder stick right, mix goes right. Rudder trim right, mix goes left.- Left flaperon is erratic while extending the flaps with aileron inputs, jitters from all the way up to all the way down while motoring. Works fine once extended. The probgramable flap motor extension time feature is cool. This doesn't happen using the Dx6i, but it has no flap motor time.- Only can get one mix at a time to work with any one flight control surface. The radio is supposed to have 8 mixes. If you program one mix, it works until you program another affecting the same control surface or throttle. Oh, and there are only 6 mix screens plus one preset mix, that makes 7 I think. All are hard to find and edit in the new menu system.- I can't assign one of my mixes to the flap switch, but can assign it to any other switch. It needs to be associated with flaps-down.Other bad things:- The TM1000 telemetry mod only does temperature without soldering. What a joke, my other-brand telemetry modules do voltage on every cell without soldering by plugging into the balance port. No RPM sensor is inluded. A big zero. Wish the price wasn't pumped up to include this lousy Telemetry implementation. Oh, and the telemetry screen is different than the main screen, forcing you not only to look down but to roller over two screens to see anything. Terrible.- The new software (which is more complex and counter-intuitive, not less) now requires that you cycle the power off to change some model settings. This means you have to lose the link to do simple things like troubleshoot Buddy Box issues. Sacrificing the link is dangerous and dumb, especially given the next problem.- The DX8 rarely connects with a steady link light. If you bind from a hardware plug, you'll get it for another bind or two, but that's about the best it can apparently do. Lots of reports of this issue and lost links on youtube and elsewhere.- The software is too onerous and complex to set up simple things like assigning expo for all control surfaces to a single switch. The DX6i was much easier to set up both the rates and the switch assignments. Plus, all the additional steps have default settings that are almost always incorrect for my taste (e.g. all rates by default are assigned to the own switches) so there is a high probability that something will be assigned incorrectly by accident unless you spend as much time testing as you do programming--and that is a lot of time.- There is a Spektrum website now (that requires you to enter your private information) to get software upgrades. I'm on v1.02 now, the most current version. Some things were fixed others were not, and new errors arise.Good things:- 8 channels.- 7 mixes.- Three-position rates and flaps.- Programmable flap motor time.- Much higher resolution trim.- More programmable timer options.- Rubber hand grips. Ships with the most uncomfortable neck strap ever (widens at the neck), but it has a strap.There you have it. The good things are major, but in my view the bad things are inexcusable. Granted, it is early in the product's lifecycle, but tell that to the people who've lost models (I almost lost one due to the trim glitch, but was able to land with nearly full left stick at touchdown). Any manufacturer of begging to get sued is probably a 1-star product in my book, so that's what I give this expensive radio.

Hats off to Horizon Hobby Customer Service
By TC
Sad to say, I purchased one from a competitor "HZ" to save the CA tax. The unit arrived promptly, but, it was an early version that needed to be sent to Horizon Hobby. However, Horizon Hobby came through again, they sent me a brand new DX8 with the new 2.01 firmware. They are, without question, the best Customer Service I have ever dealt with!The Radio is terrific! I programmed it the night it arrived, and was flying my TREX 500 the next day. Be sure to Google for helpful info from others. There are differences like the gyro gain.This is an upgrade from a DX6i. All my trade studies pointed to the DX8 instead of a DX7. The down sides were the early issues, and of course the price. But, in the end the DX8 won hands down.The immediate difference for me, was that the sticks are so very smooth. The user interface is intuitive. I like the backlit display, vibration indicator, and the audio tone is thankfully louder than the DX6i. I haven't installed the telemetry yet, but that is another great feature. There is a lot to like about this Radio.

By Damian P. Korick
I've flown Futaba gear for the last 15 years and have been happy the whole time, but recently decided it was time to go 2.4 and looking at all the BNF's out there, it made sense to get a DX8. At first I tried the transmitter plugin by Spektrum for my Futaba 9c, and it worked fine, but I tired of changing it frequently and the idea of getting a "new" radio finally overcame my hesitations. Now I have about 8 Spektrum receivers and slowly adding more. I love being able to buy BNF and fly the same day the plane or small heli arrives! I've also been moving from all nitro to electrics and while it was intimidating, again the BNF's take all the guess work out. The DX8 seems just as good a radio as the Futaba 9c, programming is different, but they are about equal there. I fly .60 nitro helicopters and below down to the Blade coaxial's and .90 2 stroke planes and below, to many of the Parkzone single cell BNF's that are a blast to fly on calm days.I haven't tried out the telemetry capabilities of the DX8 yet, but look forward to it.

Well constructed seat cover.
Good reputation, but a shortcoming.
