Hey Mike,
I totally get where you’re coming from! The first time I opened up MT12/EdgeTX stuff, I felt exactly the same and seriously considered just selling it and picking up an NB4+!! It's been in my shopping cart, then I removed it, only to put it back again but then, I decided to go on and figure the EdgeTX stuff out.
It’s true, there’s a short but intimidating learning curve. For me, logical switches weren’t logical at all at first - I spent hours getting something working that probably would have taken 10 minutes on an NB4.
But… once you get over that initial hump, the MT12 with EdgeTX and ELRS is genuinely next-level for surface rigs, especially if you ever want to do long-range, FPV cars, or just like tinkering. Here are some honest pros and cons from someone who’s been through the “why isn’t this working?” pain:
Pros:
• Insane customization: Anything you can imagine - custom telemetry / dashboards, logical switches, special mixes, scripting - custom tools. I don't think there's something you wouldn't be able to program.
• ELRS: Truly outstanding range and link quality, especially for FPV surface vehicles - no more range anxiety - I enjoy sending my cars far away on beaches or exploring fire roads for example. Not that it's needed, it's just nice knowing that this isn't an issue.
• Upgradeable: Community-driven firmware, regular updates.
• Price: For the features, MT12 is
very good value (coming from Spektrum, I was honestly blown away at what you get for the money). It's not like you'd ever "outgrow" the MT12.
• Open-source magic: You’re not locked to a single ecosystem, and you can make your own or use other people’s scripts. (If you ever get one, I’ll send you my GitHub with a ready-made custom telemetry script - pretty fun, adds another dimension to it but I admit, I'm still tempted by NB4+ because it'll soon - a month or so they promise - natively utilize new FlySky advanced telemetry!! That's a game changer and unless you'd connect additional sensors to your Radiomaster, you'd never get to that level of interesting/useful live data).
• Future and air/surface-proof: You can run just about anything and almost the same EdgeTX you get on planes, helis, drones.. so that's a huge advantage if you like both surface and air.
Cons:
• Not the most “beginner friendly” out of the box: You’ll spend some time in the manual and on YouTube..
• Overkill for “just bashing”—if you never use telemetry or custom stuff, NB4+ is awesome and easy.
• I have one FlySky TX and it feels great in hand. The MT12 feels huge and I have big hands. It's good but FlySky has figured the ergonomics better I think.
Honestly, if you just want to plug in and go bash in luxury, NB4+ is king for simplicity and it just works! No runaways

But if you like to tinker, want long-range ELRS, or want to do wild stuff (like FPV cars with smart telemetry) or enjoy 4-in-1 as your universal TX for many different models, MT12 is hard to beat. If you ever decide to give it a shot, ping me and I’ll share my custom scripts and setup tips to flatten that learning curve!
