JR marketed the XG11MV radio as a versatile system due to the interchangeable modules. I would like to utilize that capability but have yet to find a source for the two other modules listed in the owners manual....the TS-72J for 72Mhz and the TD2.4GM/EM modulating on DSM2. Has anyone else found a source for these?

Have you checked JR America ?
There is a 72MHz module on their web site: http://www.jramericas.com/51149/JRPTXMS/?pcat=480

I see the module your referring to, but it is not for the XG11. I can still buy some stuff from Horizon...just not the modules.

JR Americas in their 11XMV description overview states "For 72Mhz operation, requires
JRPTXMS Synthesized 72Mhz Module and JRPA151 Antenna." You might write them and confirm that. I would be interested as well in knowing if it works.

I emailed them (I think they are still Horizon at this point) and didn't get a response...that was last month. I have looked through all the sites and sources that I know of and haven't had any luck. The 72Mhz part number from the manual is the same as the one on the JR Americas site...TS-72J. Can't find a thing on the DSM2 module...part TD2.4GM/EM. Hobby King will probably be making a clone soon.

I believe that Horizon will soon be terminated by JR as the official importer to the US for JR equipment.
The transition has been underway for some time. So it is not surprising that Horizon carries and sells
little JR compared to their own brand (Spektrum).
Probably better to try asking 'JR America' if you have any questions about availability of JR items.

You need to be talking to them, not us.

I just acquired an XG11MV and installed the synthesized 72Mhz module and antenna from my XP9303 in it. It worked. JRPTXMS is JR Americas / Horizons part number for the NET-JS72 module that is used on the XP9303 and JR's 72MHz transmitters (other than the 12XMV) sold here.

Did you get a response from JR Americas regarding the DMS2 module for the XG11MV transmitter?? I've tried twice without any response so far. I have the Spektrum 9 channel airbourne module that was originally used to convert the JR 10X to 2.4. Physically it will fit if I remove the adapter pin from the Tx. However, I haven't tried it yet; I wanted to know if it works before destroying my new XG11.

No, I haven't heard from them....I can wait. I only wanted the DSM module for a couple of models that I already have set up. I have flown the DMSS setup now for several months and like it so much more than my old Spektrum DSM...that I am going to swap out the other rx's for DMSS and be done with Spektrum. I have never liked the cheap quality of Spektrum products even though their 2.4g protocol has to rank up there as the most innovative in 20 years.

Here's the response from JR:

"The correct module is made by Spektrum, and is part number SPMMSJR720. It is available through just about any local hobby shop or online hobby retailer.Chris Sheppard

I have contacted Chris at JR Americas to determine if the older "DM9 9 Channel Aircraft module" will work as Spektrum uses the same part number for their older DMS2 module (on their website) as they do for their new DMSX module.

Chris responded immediately; he says that either module can be used.

Remove the adapter pin located in the center of the "well" first. It pulls out and then there's room for the module.

Oct.28th:

The DM9 module did NOT bind to the DMS2 Rx at first.

I reported my problem to Chris at JR Americas; he recommend to use the "PPM9" modulation.

IT WORKED!

On page 15 of the manual, it indicates that PPM9 modulation has to be used with a DMS2 module.

I have used the FM and the DMSS modules and I am quite happy with the performance. I ended up ordering the JRPTXMS FM Synthesized Transmitter module and the JRPA151 Transmitter antenna...got them from JR Americas. You will need to remove the 14 pin connector from inside the module bay on the transmitter before it is ready to accept the FM (or Spektrum DSM) module...and don't forget to remove the antenna cap and install the JRPA151 transmitter antenna when your going to modulate on 72mhz. I have a Spektrum (for JR radios) DSM module on order from HH to cover my remaining DSM receivers and will finally have all of the modules covered...DMSS, DSM, and FM (PCM-S). I'm pretty sure other manufactures modules will work if you modulate on PPM...the XG11MV is turning out to be a much, much better radio than I thought it would.

I have (2) JR10X's I use with both 72Mhz(SelScan) & Spektrum 2.4Ghz(DM-9) without any issues with operation or range. I was considering getting the DMSS module from JR to use on my 10X's until I saw the price. Seems really pricey for a module that is probably manufactured for 1/10th the price. Maybe I'll look for a clone if they become available.

DMSS is a more secure protocol than DSM or 72mhz...depending on how much interference is in your area, you may not need it. I still use 72mhz and DSM...no issues at all. All I would say about the module pricing is R&D cost, overhead, and market cap. I don't believe that stealing is right...so won't contribute to those companies that are ripping off others products.

AndyKunz

What makes DMSS a "secure" protocol?

My Feedback: (211)

Ahhhh Andy...how are you? Happy New Year! You sir are misquoting and probably misinterpreting my comment. I am speaking about "more secure" as in levels...not "secure" being absolute. I found out about that when I paid to upgrade my DSM2 transmitter to DSMX...or atleast that's what Spektrum said I was getting...a more resilient signal when operating in dense environments like Joe Nall. Sure wish you could have helped me out earlier when I was trying to source the modules...I got it figured out though on my own and order your DM9 module.

AndyKunz

Glad to hear you got it figured out. I don't recall helping you, but with the sheer number of people I talk with in a day that's not surprising.

Just about anything is more secure than DSM or 72MHz, or any single-frequency system like those. That's why we only ever had DSM for our original park flyer system. DSM2 provided the redundancy that was needed for any real security flying, and as you said, DSMX takes it up a level.

My question is more of a "what do you think constitutes 'security' in an RF protocol?" DMSS is no better than DSMX or Fut's flavor du jour when it comes to resiliency in the face of interference. It's just "another of the same" in that regard - the ranges are similar, the latencies are similar, the capabilities are similar.

As for me, I'd never go back to DSM or 72 for anything but novelty. DSMX only!

Like you said the protocols of all the manufacturers are similar in security so there really isn't much of discussion there. I think your description of DSM and 72mhz is accurate enough and those protocols would be fine in some locations. I don't want to get off on a tangent here with protocol quality. I do however want to be able to use my radio to the capacity that it was intended hence the thread, because I do have some 72mhz and DSM2 equipped airplanes...but also it would be nice to fly someone elses airplane with a simple model setting copy and the correct RF module to make it happen from my own transmitter...I might buy a model that is bind and fly...or fly before I buy. I don't really want to pull the receiver if I don't need to. Yes, I can always use their transmitter but based on what I have seen related to throttle curves and other personal "tastes" I would rather download and make some quick adjustments from there. Also helps to know which switch does what. Someone needs to come out with a master interface that handles stored model settings from brand x and converts them to brand y...perhaps there is an App for that?

AndyKunz

Sounds like you have other JR users around. The places I've flown recently (IL, NJ, PA) finding a JR user isn't likely. They're all flying Spektrum, and with the current radio family you can export a model from a DX18 and pop it into a DX6, or take the file from your DX6 and put it in a DX18. Total inter-family compatibility. My son and I do this between our DX18G2 and DX9 all the time. You're right, being able to move files to move models is really good.

You could try asking the guy on RCG and HF about his converter. Maybe he can make you something that will let you move from one JR to another, or from a JR to a Spektrum.
