RE: PPM, PCM ?
Sonnich, I was in your shoes about five years ago. (ch Futaba systems on PCM destroyed one of my jets, seriously damaged another. I had it! That's when I tried the 12 ch MPX Profi, first with the 9 ch IPD RX, then the 12 ch. I have NEVER looked back. Rock solid reception since with NEVER an issue (that I did not cause). The MPX IPD is it! Hands down, in my experience. Forget PCM, move up!
