RE: PCM or FM RX on an electronic iginition engine?
Hi,
PCM only hides the glitches and interference. If that makes you "feel safer", then use PCM.
Personally, I use only PPM on my fleet of research planes (ca. 25 planes and all gassers) and solve any interference problems. All receivers are not created equal. Some brands are more selective and more resistant to interference than others.
