Like what was said, PCM can and will HIDE a potential problem, and it will rear it's head at the most unfortunate time.
So how do we make sure that a PCM receiver is not hiding a problem? I've heard several times that you can do all the checks with PPM and when everything is ok change to PCM. However I find that most of my incidents come from messing with my models by changing stuff around that was just fine to begin with.
