    Hobby King has released their Spektrum DX6i killer with a JR-like data entry system.  It will bind to any DSM, DSM2, or DSMX receiver as if it was a DSM2 DX6i and costs $65 + $32 (seemingly marked up) international shipping.   The only thing more spectacular than the T-SIX’s international shipping cost is the base cost of a Spektrum DX6i.

    ORX T-Six

    Z8RC pre-release sneak peak.

    It took about two weeks to get a copy of the T-SIX from the HK International Warehouse.  Initial inspection reveals a slightly higher quality product than the pricey Spektrum DX6i, the T-SIX’s clear competitive target. 

    ORX hardware advantages over the DX6i are:

  • Overall heavier, more solid feel
  • Larger LCD panel
  • Backlit LCD
  • Better menu layout due to increased screen real estate
  • Secondary navigation method via four buttons – aids data input while flying or holding the Tx
  • Secondary navigation method provides redundancy if the roller fails
  • More positive roller movement (when rolling) and enter function (when pressing down)
  • Slightly smoother gimbals
  • Slightly more stable stick grips
  • 4AA battery compartment includes a JST Plug for LiPo and Life battery support
  • Adjustable battery low voltage alarm
  • Color makes it easier to locate

    ORX hardware disadvantages compared to the DX6i are:

  • Stick position gradations are harder to see; black on black
  • Model names are not shown while selecting another model, only the model number is shown
  • Non-Specktrum buddy box, DIN plug type
  • Some thought the color was ugly; I actually like it

    Other knowns and unknowns:

  • DX6i trim buttons break easily; ORX T-SIX buttons feel and look similar in design but can’t possibly be worse
  • DX6i metal switches snap off easily; ORX T-SIX switches feel and look similar but can’t possibly be worse
  • DX6i roller fails or becomes quirky quickly; ORX T-SIX roller feels and looks better, plus has 4-button-based data entry
  • DX6i comes with a 1 year warranty; the T-SIX “warranty” is buying two units for less than one DX6i
  • ORX “Up” and “Down” buttons increment oppositely in some menu options


    Details and side-by-side with the Spektrum DX6i. The ORX T-SIX feels more solid and has a much bigger, illuminated screen.

    Note: I had to steal this DX6i’s throttle trim button to replace its broken elevator trim button.

    The ORX menus are laid out better.  The larger screen allows for a two-column format that shows more or all of your options to prevent hunting for an option.  For example, all ten models are displayed at once when selecting a different model.  Oddly, these are displayed only by Model #, not by Model Name.  The Model Name should be displayed in place of the # whenever a name is programmed.

    Here’s is a non-exhaustive video of the ORX menu functions.  DX6i owners will immediately notice the overall improvements in layout:

    Many, if not most or all DX6is have problems binding to certain DSMX receivers.  One of my DX6i’s has the bug.  My E-Flight Blade 130 and Beast 3D will not bind to my DX6i-DSMX version despite repeated attempts with all sorts of distances, timing, rituals and prayers, but the ORX T-SIX bound the same DSMX receivers every single time:


    The ORX T-SIX has a better feel overall.  The radio feel more solid, and the gimbals are smoother. 

    Data entry is easier when flying since a 4-button data entry system can be used while flying with your right hand.

    The only disadvantage, though I wasn’t 100% certain because my tests were in very windy conditions, is that the ORX could have slightly more latency.  I simply can’t say for sure since the wind prevented carefully feeling-out the difference in radios.

    Head-2-Head range shootout, coming soon….

    Orange color is easy to see.  I also liked the more modern form factor compared to the DX6i.  Like or hate the color.

    Better gimbal feel, slightly easier programming.  Could have slightly more latency than the DX6i; more testing required.  No DSMX.

    Significantly more ergonomic than the DX6i.  Similar programming power.  T-SIX is more Specktrum Rx compatible.

    Noticeably more solid than the Spektrum DX6i benchmark. 

    VALUE:  C+
    Just because the DX6i is a D-, doesn’t mean $65 gets an A.  Turnigy 9ch is only $15 more including a DSM2 module.

    Easily trumps the too-expensive Spektrum DX6i, but the T-SIX is priced about right for the feature set.

      Z, I’ve read your previous posts on the DX6i and I have much respect for your opinions on all things RC. I have one of those (my only radio due to finances) which I bought before discovering your site and I’m now scared each time I use it to send up one of my beloved planes. Have you any hopes this forthcoming ORX TX will be any good? I’m hoping so because I’ll bin this Spektrum piece of crap in a hot second. Looking forward to your review.


      It’ll be interesting to see how this one fares. I also have a DX6i, but recently maxxed the memory. I have 6 orange rx and haven’t had any issues with them. I also just bought a couple orange flight stabilizers which I’m in the process of checking out. I think I might have to get me one of these. Any idea on how soon for a street date?


      The timing cannot be better since I was looking to buy a Dx6i sometime in February (waiting for bonus). Hope it reviews well.


      Hey, Biz, I just installed ORX 3X’s in my Acro-Wot and SE5a this past weekend and aside from the finicky set-up adjustments they’re amazing! The flat 360 deg turns are ridiculous looking and silly fun!


      Speaking of knock-offs, I see that HK is offering Hitec-compatible receivers. That would also be a good Z8RC topic.


      Quote: Z8RC estimates a street price of $22.

      The BIG question: Does Z8RC (a.k.a. Mr. Z.) estimate — hopefully actually knows, and can divulge — a availability date?

      King regards,





      I am surprised they can get away with such an obvious copy. On one hand the price will be great but higher prices are part of funding Research & Development.


      I’d like to know more about the “trainer mode.” If buddy box capable with another unit via cable, this unit would be a great addition to my family.


      Available on the HK website now for $65.


      The high price is interesting, as is the lack of DSMX. We have it direct from HK’s supplier that the electronics support DSMX. Hmmmm…


      Most if not all the DSMX flyers are backwards compatible to DSM2.


      I would also like to know if you can plug in the cable from Phoenix F/S to this unit as well.


      One of the things that stuck out to me is the fact that the unit is backllit, a shortfall of the DX6i :)
