Smart idea. I am planning to do similar with the Rlaarlo CT-8A 8Ch radio I recently received.

FYI, Amain now has the MT-12s, both options. 149 so 10 bux more.
4-1 is still preorder but they have the Express LRS instock

What was the issue with the 4-in-1 version that people mentioned?

I don't remember, but you could try reaching out to Harley on Instagram. He is using the 4-in-1.
Here's the easiest way to get the correct firmware for the 4-in-1 module in the M12

Any long term updates on these radios? I am still interested, but still torn on if I want the 4-in-1 or ELRS.

I keep going back and forth on getting one of these radios as well.
Unless there is a more current list somewhere, the list of supported protocols on the 4-in-1 is still lacking on the surface side. It would only be compatible with a small portion of the receivers I currently have so it doesn't feel like a great benefit. ELRS seems easier if you have to buy new receivers either way.
Right now my MT12 is about three seconds away from being on the business end of my .308.
Some of the blame is on me, I have never updated the firmware, I am going to do that this evening. There is an easy process for updating, and a very annoying process for updating. The difference is which firmware version you have. If your radio's firmware is 2.07 or later, you have to do the annoying firmware update to v2.08, then you can do the easy update.
From what I have read, the updates I have not gotten make programming easier, I will let you know how it goes.
One of my biggest complaints about this radio has the PhD level learning curve. If you are a flier and are used to OpenTX/EdgeTX radios, then the whole process makes a lot of sense to you, and is pretty much native. This whole mess is more or less designed around complex flight systems, when you want to change multiple parameters at once, controlling multiple servos at once, like transitioning flight control surfaces quickly from a take-off configuration, to a flight configuration, to a landing configuration. However, that makes simple tasks, like setting up a single channel for a winch, a chore all onto its own. In my Spektrum radios, you just select the channel, what button controls it, and how you want the button to do. The process on the MT12 is completely different. If you are always working with this radio, none of this would be a big deal, however, if you don't do any programming on the radio for a couple of months, you have to relearn everything all over again. In short, it is not intuitive at all for your normal user that just wants simple operation.

I'm not sure I'd have the patience to tinker with the MT-12. Harley did say there's an FrSky coming out like it, but I'm not sure if that has EdgeTX or what. I couldn't find anything on it. He did say the 4-in-1 has a fatal flaw where you can't use the transmitter too close to the receiver or it doesn't work so he recommended the ELRS over the 4-in-1.
Wouldn't be surprised if it's running Ethos like some other FrSky radios. It's a derivative of opentx much like EdgeTX is, but is only available on their radios. A bit more graphical than EdgeTX on the MT12.
Been using the 4in1 since release and haven't had any fatal flaw disconnects with any receivers I've used.
Thanks for the input. Welcome to the site! Good to see a new username.
Right now I have having issues with a servo winch in my TRX4 Tonka Wrecker, the channel will not zero causing the winch to turn one direction of the other... very annoying. Connected to my DX5R, there are no issues. The problem is this wrecker needs seven channels.
The annoyance above aside, below is a video that captures my chief complaint about this radio and what a giant needless pain in the butt it is to program simple functions like a winch. To be fair though, this guy when a little advanced with his programming, but it still illustrates the point.
I updated to the latest firmware last night, which is supposed to fix some of the centering issues, as well as add in some ease of operation. I am hoping to plug the whole mess into my TRX4 Tonka and see if it fixes my issues.

So I've had this radio since the summer, and it's working out pretty well for me. I'm pretty much swapping all my rigs (too many of them) over to this radio one by one. I ended up getting the 4-in-1. I have not run into any issues that were mentioned for the 4-in-1..... BUT.... I am also not using the included Radiomaster receiver in any of my rigs. All my rigs are using Flysky AFHDS and AFHDS 2A receivers, so maybe that negates any issues that the 4-in-1 may have had?
Using this radio for 4WS is pretty awesome. I now have 4 rigs running 4WS on this thing. The mixing and ability to assign channels to certain switches/buttons/etc is pretty nice. A lot easier than what I had to do with the hacked Flysky GT3C that I have. The big seller for me is the cheap Flysky AFHDS receivers that I can use.

You can fine tune the center point of whatever channel your winch is connected to if you have a bit of drift. Same screen you set endpoints, Outputs.
Nope, there are about six different ways to move the dead zone, and to expand it, none have worked. The firmware update gives a couple of new options, I am going to try those this evening.
As far as my overall annoyance with this radio is that my RCing goes in ebbs and flows. Right now I am working less than 10 hours a week OT, and I no classes are in session, I have time to build, modify, and upgrade my RCs. In January my workload will increase, as well as classes starting again, I will likely not do much building, which means little changes or programming in the radios. In four or five months, I will likely have some time to get back into again. My Spektrum radios are fairly easy to relearn, ExgeTX, not so much...
