Yes, I'm using the Spektrum DX6 gen 2 on this plane...and my others. I also have a DX8 gen 2 sitting here that I was going to use on the future big gassers when I get to that point. I also have a Futaba T8J sitting here, but it doesn't have voice, which I really like. Should I sell off any of these rigs? I've also been looking at the Graupner MZ-24 Pro system. I do not want any radio system failures once I get into the giant scale birds if it's possible.
