Outrunner Posted January 30, 2021 Share Posted January 30, 2021 Hi guys. After originally asking if it's a good idea to buy Taranis with a 4 in 1 module to run my Hitec and Spektrum receivers I was advised it was an even better idea to get a Radiomaster TX16s, after a bit of convincing I decided on a Radiomaster and despite my initial reservations I'm very impressed. Also I was in impressed with the service from HobbyRC, good advice and fast delivery (usual disclaimer, I'm nothing to do with HobbyRC). Today I flashed my TX16x following these instructions Radiomaster updating open Tx There is a lot more useful information on the same website, I'm still exploring it.

Trevor Crook Posted January 30, 2021 Share Posted January 30, 2021 It looks very well specced for the price. A couple of questions: How do you switch between the different protocols, is it done via the buttons and screen? If using with Spektrum rx's, does it support Modelmatch?

Phil McCavity Posted January 30, 2021 Share Posted January 30, 2021 It's OpenTx so you need to use the 'Model menu' button to scroll through the protocols, the screen is touch capable but I don't think that's been enabled yet? No idea about the Modelmatch, I don't use Spektrum. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted January 31, 2021 Share Posted January 31, 2021 I know that DSM2 systems shouldn't be used in the UK, but does it work with DSM2 receivers, I know DSMX receivers will work with DSM2 transmitters but not the other way round. At the moment I've got an old Dx6i DSM2 Tx but if it breaks I might need something to fly my old UMX models. Also is telemetry supported on all protocols that have native telemetry support, or just some protocols. Quote Link to comment Share on other sites More sharing options...
Dickw Posted January 31, 2021 Share Posted January 31, 2021 I belive it uses the basic Multi Protocol Module system and so should support all the standard protocols listed on the MPM website (firmware may need an update). DSM2 is cerrtainly one of the listed protocols. Lost more information on the capabilities of MPM on that website. Dick Quote Link to comment Share on other sites More sharing options...
Outrunner Posted January 31, 2021 Author Share Posted January 31, 2021 Trevor, I've not programmed any models yet on my Tx16s but I'm informed that when you program a model then you enter the required protocol, so when selecting a model the correct protocol is selected. I don't yet know if modelmatch is supported. Frank, DSM2 can be used in the UK but new transmitters cannot be sold. Not sure that leaves the 4 in 1 modules as they support DSM2 and DSMX.... My transmitter is CE marked so I'm taking that as legal to use. I'm led to believe that telemetry is supported in most cases but again I've not yet bound a receiver and tested it. I hope it does..

Phil McCavity Posted January 31, 2021 Share Posted January 31, 2021 The binding to a protocol gives the option to assign a number, would that be similar to ModelMatch? Quote Link to comment Share on other sites More sharing options...

So the user has reference back to the retailer, who has reference back to the manufacturer, who by registering these certifications takes ultimate responsibility for the legality.

One final point from me on this debate as there is some nuance... It isn't illegal to sell DSM2 specifically; it's illegal to sell a transmitting device that is not compliant with the ETSI regs (at the time of writing the version that applies is EN 300 328 v2.2.2 I think), and DSM2 as built by HH did not comply. As a result they withdrew DSM2 TXs from sale in 2015 when the regs changed as they did not want to re-engineer the protocol (they already had DSMX that complied so it didn't make sense to do so). However, the MPM does not transmit HH's original DSM2, but a reverse engineered version. Since there are multiple ways to comply with the new regs by tweaking duty cycle etc it is perfectly possible that what is transmitted by the MPM when it links to a DSM2 RX is legal. Since it is the reverse engineered version that is being certificated (along with all the others in the MPM) as compliant by the manufacturer, all is well from the perspective of the user. As such there is nothing illegal about buying or operating a Radiomaster TX in the UK or EU. Do I believe every protocol in the MPM complies with ETSI regs? I somehow doubt it, but since a) the manufacturer has assumed any risk there for purchasers and b) I will only be using Frsky and DSMX only I'm not too worried tbh. YMMV.

Outrunner Posted February 1, 2021 Author Share Posted February 1, 2021 MattyB. Thank you for clarifying the DSM2 issue, very nicely explained. Hopefully that issue can be put to bed now. Nice comprehensive list of Radiomaster resources, keep them coming. Has anyone tried the Radiomaster Tx12? Smaller than the average transmitter but a good size for putting in a backpack and going down the park or up a big slope. Phil. Quote Link to comment Share on other sites More sharing options...

I thought the reason why DSM2 doesn't comply with the ETSI regs is it doesn't frequency hop, nothing to do with duty cycle etc. Having just checked the MPM code, as far as I can see the implementation of FrSky D8 protocol does the same as the original FrSky D8, so as FrSky D8 doesn't comply with ETSI, neither does the FrSky D8 protocol on the MPM. Also, the MPM allows you to select FrSky D16 FCC, that doesn't comply with ETSI regs. Mike Quote Link to comment Share on other sites More sharing options...

It is so long since I have used a non-FHSS protocol I had forgotten DSM2 was a "pick two and stick with em" protocol, apologies.

I still don't believe anything would ever come back on the user in the event of an accident (proving the non-compliant firmware contributed to the incident would be incredibly hard), but there is a residual risk there, however small. I guess the regs were never intended to cover Transmitters that had such a wide range of configuration possibilities, hence the problem.

Peter Christy Posted February 2, 2021 Share Posted February 2, 2021 I recall hearing a while back that the EU was trying to ban all radios with programmable firmware. What has become of that proposal, I don't know. I DO know that Ofcom take a somewhat more enlightened attitude to regulation than the old Post Office did, and part of their remit is to do away with unnecessary red tape! I've argued before that the EU LBT regulation was totally unnecessary, and that its sole purpose was protectionism. Now that we are no longer in the EU, I wonder if the BMFA (et al) could be persuaded to approach Ofcom with a view to removing these pointless restrictions? After all, it seems to be totally unenforceable, and the sky hasn't fallen in as a result of people still using DSM-2, D8, etc... There used to be a thing called the Joint Radio Control Users Council, comprising mostly importers, manufacturers, BMFA and any other interested parties. Ofcom usually sent someone along to attend. It was a useful forum for discussing issues like this with the regulator, but seems to have fallen by the wayside. Perhaps time to resurrect it? -- Pete Quote Link to comment Share on other sites More sharing options...

What has become of that proposal, I don't know. They weren't trying to ban all programmable firmware, but they did put clauses into law back in 2015 to put the onus on manufacturers to actively prevent non-compliant firmware being loadable on their devices! It is in EU Radio Equipment Directive 2014/53/EU, sometimes dubbed the "EU radio lockdown directive". Of course that now also means it's part of the UK statute book after becoming UK law when we left: "Article 3: ... 3. Radio equipment within certain categories or classes shall be so constructed that it complies with the following essential requirements: ...(i) Radio equipment supports certain features in order to ensure that software can only be loaded into the radio equipment where the compliance of the combination of the radio equipment and software has been demonstrated." The very fact we are still having this debate in 2021 though shows how pointless it is and how little interest the authorities across the EU have in enforcing it. Part of me agrees with the rest of your post, but I doubt there will be much appetite for changing these regs now we have left. Anything we manufacturer still (in theory) would have to comply in order to be sold in the EU, and it is not as if we will get more access or a better trade deals with other non-EU countries if we do this.

MattyB Posted February 2, 2021 Share Posted February 2, 2021 Anyway, back to the Radiomaster... I setup my TX16SE last night, and very impressive it is too for the money. The screen is clear and bright and the gimbals very smooth; the throttle ratchet is subtle, but nice once you get used to it. The only real let-downs are the poor quality sliders on the shoulders which feel somewhat baggy and lack a strong detent. I also found the screws on the gimbals are a little soft, so be careful when adjusting them or you might round them out. Setup went perfectly following along slowly with the videos - I've upgraded OTX many times on other radios so that was straightforward, but it was pleasing that the MPM config was easy too. I had no problem updating it to the latest MPM firmware and "cloning" the RF ID of my Taranis; that meant I did not need to rebind the models I was transferring to it. Clever stuff! My only real doubt is the physical quality of the switches, but tbh they feel no worse than on my X9D, and even if a few wore out after a year or two for £80 I don't think I could really complain!

Gary Manuel Posted February 2, 2021 Share Posted February 2, 2021 Hi MattyB. My ears pricked up when you mentioned cloning your RF ID. Presumably, that means that both transmitters can now control all of your receivers. Is this a good idea? Hopefully, you haven't sold your old tranny to a club member.
