Failsafe when set on throttle will at least let you know when interference occurs. It has saved three airframes for me over the years. I don’t fly well enough to know the difference between a wind gust and interference.

It appears that many FM (PPM) systems will hard over servos on interference and PCM will simply leave servos at last known position, which seems safer.

Experience has shown that soon someone will show up on your frequency. He will probably be a beginner without a full understanding of the antiquated pin control system.
