RadioMaster TX16S Mark II MAX Edition 2.4GHz 16 Channel EdgeTX OpenTX Radio Transmitter Leather Grips CNC Finished Components Mode 2 (Carbon Black, ELRS w/ AG01)

Pair this with the 4-n-1 module that is sold for it and you can connect to hundreds of brand receivers with the quality and performance of the RadioMaster Transmitter.

this is a programmable, general purpose transmitter. YOU have to customize and actually program it to be useful. so, expect weeks and weeks of YT videos and reading before it makes sense. bardwell's videos are a good place to start, to pick one.I converted all to ELRS recently so I picked the elrs version, still letting me use JR plugins for everything else (4in1 and longrange/900mhz modules).you really do have to know what you are doing with elrs, though. its really good, but its the hardest thing to get working since you have to BUILD SOFTWARE at home, on your pc, for the combo of hardware you use and the common passphrase you want for your 'network' of flyables/drivables. flashing the radio was not hard and getting elrs to come on to wifi so I could flash IT, took a bit more effort. once you get it working, its a 'leave alone' thing and the work is done and its all fun from then on.elrs on this radio 'only' goes up to 250mw. the 1w versions all need external power and there are new JR modules that do that, but likely you wont need more than 250mw; and at this power level, there is no need for a fan.I got this unit from the marketplace 'used' but it came almost brand new. the box was beat up and they shipped in that box (!) but it did get here ok. was worth the savings to get a refurb version. I think the elrs version is the most returned since people find it hard (it is) and they give up. dont give up, its worth it and it works well once you finally get it all configured.one thing I dont like: the sticks are M4 thread and not M3. that limits my choice of aftermarket colors and styles. my jumper t16 (nearly the same radio) uses m3 threads and I find that smarter. nothing you can do about it. I dont love the stick-ends that come with the radio but they are not a showstopper.I do love being able to charge from usbc, unlike my older jumper radio.touch screen with 2.8 edgetx works ok. sometimes have to click twice but that's their sw, not the hw doing that.there is some speaker audio noise with high DC load as others noted but its not a big deal, really. minor bug. I do use audio (bardwell audio pack is free) and I dont use crossfire high-current modules, just 4in1 100mw common ones and those dont cause the speaker noise problem.leather side grips are not great but not bad. they could have been better, but they dont suck, either. sort of a no-op ;)gimbal tension was too tight for my liking; there are spring settings to lighten it up but its still a bit too tight. some may like it that way. these are the hall gimbals. I dont have the ag01 for this radio (I do on my zorro) and tbh, I dont see the need for the ag01 at all.generally, this is THE standard radio to get if you do anything hobbygrade. again, worst part is that its a programmable computer and you have to realize that. you can use 'recipes' from forums and get up and running, but it takes lots of tutorials before you really get all the configuration you can do; and that's THE POINT of a high end radio like this.
