Yup, I am using the Spektrum DX6 (AR6000 rx) in my BCPP which is eCCPM of course, and in my Heli-Rex TMax 420 which is mechanical ccpm, and I am really happy with the Spektrum system. As soon as they issue a TX-only version of the DX7, I'm buying.
No more worries about flying into your transmitter antenna!
