The ar6000 is a good rx you can use the 6000 in a glow plane, you need to bolt the 6000 rx on the bottom of the plane, with the two wires expose, good luck.

Pepatrick That's exactly how i bind my spektrum,also continue to hold bind button down on transmitter about ten seconds longer after led lights go solid,pull bind plug out of receiver.

Any news of any such on the horizon? I have been waiting for this technology to appear commercially and to mature enough so that it's useful for my turbine jet projects! Keith

if you want to continue using the Multiplex 4000 , I have recently succeeded converting mine with the Hitec spectra 2.4 module and there Optima line of receivers but you only get 9 channels.

Great link! Now if I could only find an MPX4000 Tx that is available! And they have elected to go with FHSS technology, as well.

I'm on a Multiplex list group with Yahoo, and you see the 4000 go on sale on a regular basis.

With the mods I have made, I am hoping to keep my 4000 alive for a very long time, I might even buy another one as a backup, ya I love it, still ahead of the competition considering when it came out....

if you get one and want help to convert it I am doing this for anyone who wants it but only with the Hitec Spectra module, I will do it for you for the cost of material .

I originally posted a question here asking for a comparison regarding Futaba's and Airtronics choice of freq hopping vs. JR/Spektrum's frequency-pairing way of doing things. My father, an electronic engineer that has spent years in developing electronic technology in the military, points out that freq hopping has been used in the military and by other agencies for a very, very long time when secure communication and data transfer is required.

The majority of 2.4 related discussions I see here and on many other forums that have to do with binding problems and other system issues all seem to be from JR/Spektrum/XPS users. It's very rare to see a post from someone using Futaba systems (other than the voltage issue, which I understand has been resolved for some time now) or the Airtronics 2.4 systems.

I chose to break in to the 2.4 way of life with the Futaba 10C and the Airtronics RDS8000 systems, and I have been very happy with both of them, using them to fly some 33% scale gassers, a Comp Arf Eurosport jet model, and most challenging in my opinion, some all composite gliders with lots of carbon (some were ALL carbon), which I routinely fly at very long range. Not once, not ever have I had a single glitch, nor a loss of binding, and I feel that I have had ample opportunity to push those systems to the limits with regard to range and noisy environments.

One limit that I have NOT pushed is the operating voltage. I ALWAYS keep all batteries fully charged, and I always use batteries that provide a reserve of voltage and capacity over what might arguably be adequate, so I have nevered challenged the systems with regard to operating at minimum voltage. That is only smart, in my opinion.

Airtronics have finally come out with a good 10ch radio, and I have traded my Futaba for that. There was no problem with the Futaba. I just happen to be more of a glider guy and Airtronics has always had the edge on programming for gliders (Futaba needs to work on their manuals). JR did good on that issue with the 9303, but with one less channel and a 2.4 technology I don't want to use, it takes a back seat to the SDG-10 for me!

So far, my experience with both the Futaba and the Airtronics systems is that you bind your Rx one time, and that's it - never think about it or worry about it again. It's my own personal experience, but there it is. Others may have had problems, but I haven't. I'd like to point out that it is much easier to find a JR or Spektrum system for sale on the forums everywhere, but finding a good deal on an Airtronics or Futaba system is much tougher! That speaks volumes, as far as I'm concerned.

Thanks, Roger. I would only go with it if I can get the full 12 channels. I now have the Airtronics SDG-10 and I am happy with that radio.

I might have to pick up one of your 30% S-Bachs, though! It will have to wait until later in the summer, though, as I have just used up all of my toy budget for the next few months, according to my wife!

I have had the same experience with my RDS8000. Bind it once and forget it. I have had absolutely zero issues with that radio, and plan to pick up the SDG-10 some time this year.

I bound my Viking old timer when i went FAAST 3 year ago, and havent had to bind it again. Still going strong.

[fsone]

I have never had a problem binding my DX7.There are 4 individuals in the clubs i am involved with who fly air and heli for 3yrs now have never had a glitch or any problems.I switched from futaba to Spektrum and happy i did!.Go with the best and forget the rest.

Roger, what's the URL for the group? I want to join! Love my Airtronics SDG-10, but nothing beats the 4000 for sheer versatility!

I think you are confused, it was Spektrum/JR that had the voltage/brownout issues. Futaba never suffered that problem. Futaba did have one RX that would shut down in high heat environments (over 150 degrees or so) and the zero GUID issue on some 7C and 6EX radios. Those issues are both in the past now.

As far as gliders go, I have found Futaba to be very robust. I have been flying the 9Z and now the 14MZ in Open thermal duration, DLG, RES, and scale planes for several years. With the 12 to 14 channels radios I have yet to dream up something that the Futaba radio cannot do for me.

Not sure if you are aware that there is a glider pilot living in Havasu who flies Airtronics. Fellow named Daryl Perkins, seems to be a fair stick.

BTW - I've recently logged two flights, one an an AVA Pro RES glider (lots of CF including an all CF tailboom) and my 3.8 meter Xpolrer Open TD planes. I have documented line of sight distances in excess of 2,100 feet with rock solid performance. I am mostly using the R617 in my gliders.

Zeeb good comments on the ar6000.You're right should only be used with park models.And pilots wonder why they have problems.majority of problems come from pilot error,not knowing how to work their equipment.Read YOUR MANUAL.
