There is no different in range of the two radios. 1 has 6 channles and the other has 7. The 6DX is a top notch full rang radio and is used for things other than park flyers. The sending speed and strngths are the same. The difference in what a park flyer is that you get micro servos and batteries in the package. The micro servos would not have enough strength for a .40 size bird. The receiver and transmitter would work great in other things. You would only have to get bigger batteries and servos. The bigger radios usually only differ in that they have more programs, end points and mixes. Yes, the Futaba in a great radio and worth every bite of the $199. I use Futaba and JR and plan to upgrade to the 2.4 modules.
Hope this helps

this is right off of the spektum webpage
"So while the AR6000's superior range may tempt its use in "regular" sport aircraft, please don't do it. Use the DX6 for park-flyers only. It will provide a very safe, satisfying experience for your parkies."
this too
"Why parkflyers only?
This unit was specifically developed for sport park fliers use. It has plenty of range for parkflyers. Just as we have a different product for airplanes than cars, we'll have a different product for sport flying aircraft that fly at a much farther average range than a parkflyer. We wanted to keep this unit small, light and affordable - all attributes we felt park fliers need. Sport flyers have different needs - and we will have products for them, all in good time."
it can't be just the range though because the dx6 runs up to 1/2 mile
this is off of the dx7 comparing it to the dx6. Latency means response time, so there it is in writing that the dx6 is slower than the dx7 just because it is a dsm radio and the dx7 is a dsm2 =)
"A: DSM2™ technology is Spektrum’s second-generation proprietary spread spectrum protocol. DSM2 (Digital Spektrum Modulation 2nd version) is optimized to allow all types and sizes of aircraft to be flown.
With DSM2, latency has been greatly reduced and, in fact, the system offers faster response time than any brand of 72MHz PCM system."
also according to the website the dx7 has more range than the dx6 because they say do not fly giant scale rc with the dx6 because you could go out of range, and it says the dx7 is suitable for all sorts of sizes and makes of rc, and has a 33% knife edge 540 on the tesimonials page
quote from page 2 on the dx6 manual
"The DX6 system is designed for parkflyer type aircraft only. This includes all forms of compact electric and
non-powered airplanes as well as micro electric helicopters. While the system has more than adequate range for
these types of aircraft, it is imperative that the system not be used in larger aircraft that could exceed the range."
