I've had a DX8E for years, but finally bit on the Open/Edge tx stuff. I got a Radiomaster Zorro for $120 (1/3 the price of the DX when I bought it). Learning curve? YES. Worth it? Definitely. And I'm the guy who still uses his FM radio sometimes. I can now use ANY RX I want (except ELRS, but I can always add the module). I recently dug out a 15 year old RTF kit with an oddball RX from the early days of 2.4 stuff, protocol was something I'd never heard of, but lo and behold, it was there in the Radiomaster list and it bound right up. And is my old DX8E now useless? Nope! With the 4 in 1 external module ($60) I can use it as a DSM RX and use the DX8E as a trainer TX. I have it set to give control of just rudder or both rudder and elevator using a 3 pos switch. So for the Radiomaster Zorro and both the 4 in 1 and elrs modules, you'd be in for about $250 and be able to use any rx at all plus be wireless trainer capable. It's compact, inexpensive and every bit as capable as a big touch screen TX. And it's very easy to immediately disable the annoying voice prompts. The only complaint I hear and agree with is the small internal battery capacity of the zorro, but it has a 2s balance port socket that allows you use any 2s pack. And there are convenient strap holes to mount said external battery. I love it and will probably never go back to a box radio. Just my 2 cents.
