In my opinion there is no doubt, PCM is the only way to go especially if its a dual conversion PCM receiver like Futaba. You spend way to much money on these rigs to skimp $50 or so to go FM. I have seen the benefits of PCM several times over where FM guys are getting hit and crashing. I have yet to see a guy lose a plane, or even glitch, due to interference with a PCM reciever. In my opinion, there is really no logical reason NOT to go PCM other than cost on anything other than electric park flyers. On the other hand there are a lot of guys who never fly anything but FM and have never had a single problem....[sm=confused.gif]
