Throw Away Your RTR Radios! Radiomaster's MT12 Puts FPV Drone Tech in a Surface RADIO?!?!

[@Mr.Laidukas]

In EdgeTX operating system there are programs, technicaly called LUA Script. You can run ELRS script and with that program change settings. For example increase data rate to get extream low latency for racing or lower data rate to drasticly increase control range and use receivers with internal antenna without risk of losing link. Great video, I flybdrones with these seamtems for years, and only ocasionaly drive cars. So glad with MT12.

[@kpopRC]

OH totally! my mind was blown, checking out all the scripts people have written! I'll do an update video at the bottom of my idiot mountain an into the vally of despair. I'll dunning kruger my way out of this in no time.

[@SlippinFPV]

Same!!! I am super hyped on this radio!!

[@fc1133]

So, I recently acquired the Radiomaster MT12 with the intention of replacing all my TRAXXAS and Losi RTR transmitters. This decision seemed logical to me for several reasons: 1. Many RTR transmitters get the job done but lack ergonomic comfort, prompting my search for a more user-friendly option. 2. Stock RTR radios often limit customization options, necessitating the use of a Bluetooth dongle to connect the radio to a phone for parameter adjustments. While I seldom modify settings once my cars are set up, the inconvenience of switching the Bluetooth dongle between transmitters or purchasing multiple dongles for each radio seemed impractical and expensive, especially considering the number of radios I own. 3. Several of my cars feature receivers with built-in stability management. Swapping them out for receivers from brands like Futaba or FrSky, which lack built-in stabilization, would require adding an external gyro. However, the challenge lies in the waterproof receiver box, making the addition of a gyro somewhat tricky, though I'm considering if it's possible since the gyro doesn't necessarily have to be inside the receiver box. 4. The accumulation of numerous radios from each car's purchase led to the inconvenience of managing and storing around 15 radios. 5. Consolidating to a single radio would allow me to sell the surplus radios. 6. The built-in 4-in-1 module of the Radiomaster MT12 would enable me to retain the original built-in receivers, which vary among TRAXXAS, Losi, FrSky, and some unknown brands. However, my plan encountered a setback when I discovered that the Radiomaster MT12 only supports ONE TRAXXAS receiver, and I don't have that particular receiver in any of my cars. Additionally, it does not support LOSI receivers, at least not at the moment. To proceed with my original plan and use one radio for all my RC cars, I would need to invest in 15+ compatible receivers and numerous gyros. This investment doesn't align with my preferences. Given these considerations, I'm now contemplating whether to keep the Radiomaster MT12. Excluding the 4-in-1 module, I'm questioning what makes this radio special and whether it still holds value for me.

[@jhue73]

thats what i wanted it for but now i wont get it. i have quiet a few losi receivers. my frsky x9d with the 4 in 1 module does bind and fly my micro planes and helis that have spektrum receivers. losi uses spektrum which is dsmx,dsmr so the 4 in 1 does support that. so not sure why it wont work with some spektrum receivers. i tried to use the frsky x9d with the 4 in 1 module to bind to my tenacity with the spektrum sr6200a with no success. it may have something to do with channel order but im not sure. if i was gonna by all new receivers i would probably get the nb4.

[@jhue73]

i just tried to bind my 4 in 1 module again to my spektrum sr6200a receiver and it worked. you have to set it to DSM R1F and i set the channels 1-7.

[@bitogre]

I want to know if this (with the 4-in-1 module) will work with the Losi Promoto mx 1/4-scale motorcycle and, if so, how you would need to program it for that RC motorcycle. It would also be interesting to see if this motor cycle will work as well with a ELRS receiver but I doubt it as the receiver provides some stabilization functionality.

[@kpopRC]

Yes, who knows if there will be recievers with added gyro stability in the future. i assume so. This is an opensource hardware that is just starting with surface. It will be amazing to see how fast it evolves. Already has input for head tracking fpv. I'd wait for an ambitious community member to lay out the promoto control. seems tricky.

[@bitogre]

@@kpopRC That is why I would start with the Radiomaster using the 4-in-1 module which should work with and get telemetry from the stock receiver.

[@kpopRC]

it's so thick! im in the curve for sure. I bet head tracking is possible.

[@rcvg69420]

Headtracking is possible via the DSC port just like it is on any EdgeTX/OpenTX based radio. I've set this up before with my Taranis, I think the project is just called "headtracker". If you google headtracker gitbook you should find it. You just flash this firmware to a specific arduino nano, like 30 bucks, and put a headphone jack on it, then it sends a ppm signal to the radio's DSC port you can use to run a couple servo channels for your headtracker gimbal. Cool stuff!

What is the difference between the ELRS and 4 in 1 versions?

[@kpopRC]

the elrs version uses elrs radio protocol. the 4 in 1 version uses 4 known protocol chips to link to existing radio systems. not all radio systems. I went with expresslrs because it's open source, and the receivers are 10 dollars for telemetry and 5 channels.

[@toysforboysrc]

Yo K-P0P… Does this MT-12 have the same types of tuning features as the radiolink and futaba transmitters have? Like throttle EXO, throttle POINTS, CURVES, servo speed, ch Mixing..?

[@kpopRC]

YES! and it has way more options. like you can change mixes with switches. it's basically a fully air remote with heli mixing as well, so you can do tank steering with two escs, and and like swash plate style mixing. It's probably the easiest to learn as well once you understand the hierarchy of mix outputs and curves. Each channel, can point to a curve, and you can switch the curve graphs by name by switch. so it's pretty bananas. this is what happens when 10 years of opensource gets ported into a surface remote.

I wouldn't hold your breath with spectrum. I don't recommend the 4in1. but you can add piggy back transmitter modules to get other protocol on the expresslrs system. it's open source and it's the beginning of a lot of development. I'm sure gyro and light controller specific recivers are coming like the betaflight boards for drones.

[@swissfreek]

What's your method for determining what protocol to use for all those cheap RTR transmitters you had piled up on your bench? My kid has some of them, like IMEX, and so far I haven't been able to figure out what protocol to use for any of our current transmitters with the multi-module. I know the module is mainly air-centric, but like, I don't see a way to use Traxxas TQi, or Spektrum DSMR, or this IMEX, or anything else?

[@kpopRC]

Hey swiss! You can get the expresslrs version. because you can piggy back transmitter modules. HOWEVER! the company needs to allow these 3rd party companies access to their protocols to build hardware, traxxas im sure is not going to let that happen. I am just planning on purchasing a 20 dollar receiver for any new model. at least with expresslrs, new receivers are added into updates that are available free to upgrade your remote. This just seems like a cheap way into something more reliable, and robust.

[@swissfreek]

@@kpopRC yeah I agree, I went with the ELRS version. I have a multi-module that I could slide on there already anyway. It’s not that big a deal to put an ELRS receiver in most things, but the smaller stuff in particular often has an integrated ESC so that means adding a new ESC as well. But they’re so small that’s pretty cheap as well.

id love to know if it can do MOA mixing well.

yo man MOA crawler mixing? if so. for sure. this thing is as programable as a flight remote, from swash mixing for heli's to tanks, to multiple escs. it's going to take some time for the communities to post their mixes. but considering you can share them via a file.... yeah this is going to change the game for any application that needs heavy channel mixing.

[@ninthislandrc]

Thanks for the video...FANTASTIC info. I knew 'something' like this was coming from RadioMaster...but, I forgot to "keep track" of it during the party few months. However, something you didn't point out...something you should have pointed out...is that the "long distance" ability, and "multi-mode" ability are NOT from the same MT12. In a way, you've accidentally given 'misinformation', making it appear as if there's a single version of the MT12, and it has all the abilities you described. Unfortunately, the truth is that there are two DIFFERENT versions of the MT12 (and, two sub-versions of each), as follows: 1) ELRS version - This version is capable of "long distances", for which you need to use the RadioMaster receivers. As I understand it (based on RadioMaster's own marketing info), this version is NOT compatible with receivers from other brands. 2) 4-in-1 version - This has the "multi-mode" ability. This is the version having the ability to utilize receivers from other brands. However, as it's power output is lower than the ELRS version (100mw vs 250mw), it does not have the built-in "long distance" ability. That being said, both versions can utilize a TBS Crossfire Nano module (both come with that Crossfire Nano module holder), to achieve even greater distance control. TBS has tested the aerial ability of their Crossfire to 45 miles. While they haven't tested the maximum surface control distance, in a conversation I had with them several months ago, the estimates control distance was expected to be at least 5 miles. However, it needs to be said/understood that, in order to achieve such distances with the TBS Crossfire Nano, you will have to not only purchase the Crossfire Nano Transmitter module, you will also need to purchase TBS Crossfire Nano receivers. To everyone reading this, the MT12s do seem to be fantastic. However, BEFORE ordering, do your research, so as to make sure you don't order the wrong version. Again, there are TWO DIFFERENT versions of the MT12 - the ELRS version, and the 4-in-one version. On top of that, each version has two sub-versions - FCC & LBT (which has to do with region). In other words, technically, there are four different 'versions'...and, I'm sure no one wants to accidentally order the wrong one (returns can sometimes be a bit of a hassle, especially if you're the one having to pay the return shipping cost because you ordered the wrong 'item'). So, before placing your orders, is best to determine which version (ELRS or 4-in-1) you want, and which region 'trim' (FCC or LBT) you need.

[@kpopRC]

Maybe i wasn't clear. but even the expresslrs version of this radio will allow for transmission modules, so you can still pick whatever protocol you want regardless of either version.

[@ninthislandrc]

​@@kpopRCI do see that now...but, going that route retirees purchasing the external 4-in-1 module. The radio, when purchased, contains either the internal ELRS module, or internal 4-in-1 module. Also, I looked over the 'compatibility' list, and it didn't appear to be as good as I was hoping. A LOT of protocols are not on the list. For example, it can connect to the FlySky AFHDS2 & AFHDS2 protocols, but not the newest AFHDS2 protocol (which the Noble NB4 & Noble Pro use). Seems, the 4-in-1 module can't connect to most of the newest protocols used by other manufacturers. It can't even connect to receivers using several of the recent (not referring to the 'newest') protocols used by some manufacturers. Honestly, the more research I do on the MT12, the less interest I have.

@@ninthislandrc that is due to the vendors being closed source and no one has been able to reverse engineer it yetl The hardware is capable and would be a software upgrade if anyone figures it out

[@kpopRC]

www.multi-module.org/basics/supported-protocols here are the supported protocols with the 4 in 1 unit! so awesome!

[@ninthislandrc]

​@@kpopRCAwesome for those in Europe & Asia...but, for those of us in the US, not as much. The great majority of the protocols listed aren't even seen here is the US. I want to like this radio...I REALLY do...but, honestly, I just don't see US RCers clamoring to this one. It would be like trying to sell a multi-screwdriver 10-in-1 tool, when 8-9 of the screwdrivers are JIS, and only 1-2 of them are Phillips. Plus, the most popular protocols aren't even there. When I think of the most popular radios in the US, I think of the more recent releases from Futaba, Spektrum, Airtronics (which might be closed), and FlySky. I don't follow Airtronics, so I don't know if their latest protocol(s) is/are included...but, as for the other three, none are included. The MT12 is fantastic for everyone currently using radios from other (ie. lesser-known) brands...but, from what I can tell, for those using more recent releases from the more popular brands ex this radio will probably be a no-go. As I said, I REALLY wanted to like it...but, I just can't.

4 in 1 would be better

[@kpopRC]

same price.

[@craigcupit1917]

I have a 4 in 1 but everything I buy goes ELRS. Only my helicopters are not ELRS due to no RPM telemetry or ESC temp reported back.

[@kpopRC]

maybe that's an expresslrs 4.0 kind of thing. Seems like many people have made that request.

[@marcoshuerta8661]

I think it was kinda a flop they could have done so much more...

[@kpopRC]

230 dollar radio. more featured than radios 400+ dollars? you're a hard one to please.

[@chevysub432]

Not happy with this "crap" Can not bind to Traxxas Trx4m recievers , Fms recievers , Furitek recievers .. Useless for me

[@kpopRC]

I dont use or recommend the 4 in 1. however there are a lot of people happy with the 4 to 1. it's your fault for not checking compatibility NOT the radios.

[@chevysub432]

The sellers here claimed this radio can be used with almost everything. But not even Flysky receivers without flashing.. So. Useless for me and several buddies buying this. Lucky we got a god return policy here we live.

[@kpopRC]

you do you. there is pdf i posted here that shows compatibility. you didn't look for it, and assumed that it would work. glad you got your money back but this radio and what it has started is incredible. some people will understand, some won't.

[@chevysub432]

I did not look for it? What kind a stupid are you ?

[@1ubby]

Not really cool if your are deep into rc like my self I have better options. But respect you trying to make few bucks and not be on welfare!!

[@kpopRC]

edgetx and betaflight have evolved faster than any surface radios in the last 10 years. Guys are talking about leaning out the packets for lower latency. i don't see that in any "better options". the whole main stream surface radio market market has been stunted. it doesn't take much to see that.

[@kenb6565]

Please explain. Not sure what you could see bad about this.

[@ricardoferreira2811]

Another puppet review.

[@kpopRC]

oh no. are you crying?
