LOL - I know..
I would not suggest a Radiodisaster. LOL
If you like, I'll send you an Ethos radio to see if you like it or not. I suspect you will not.I just did this for one of my locals that flies old Hitec radios with FrSky RF. I showed him some things in the radio and told him to take it home and play with it, see it it grows on him. He did, but don't think he even turned it on. Much like you he is perfectly happy with that setup. Can't argue that.
With this said - Folks may want to stock up on XHT conversion modules and ACCST receivers while you can. FrSky has already run out the XJT modules. FrSky is phasing them out and there is not enough demand for me to keep them in production any longer. I do not think you will see a replacement for the XHT either. I think we can keep the X8R and X4R in production for a while.. (I have over 300 X4R in stock right now, that is a few years supply.)
Ethos is what I consider the very best programming we have ever seen on a radio, but it is different than you are used to. When we sold nothing but OpenTX radios (same thing as Edge TX) we had about a 20% return rate as they are rather difficult for some folks to adapt to. With Ethos our return rate is pretty much zero, it is that good.
As the previous poster stated, once you have your first model setup, you can pretty much copy it and use it for a base to build your next model off of. This is really handy for flapped models.
