RE: Mini PCM reciever
Dave
The IPD stuff is better than the any standard PPM RX........ In case I wasn't clear these intelligent RX's are running neck and neck with PCM RX's and may even be better in some aspects. read through my comments above and you'll note that this technology affords all the benefits of PCM and then some.
Multiplex the innovator of PCM protocol to the RC world no longer offers PCM and has moved into the future with IPD RX's.
