First off, if I were stalking you I would have said something in that thread. Being a trained composites technician I occasionally do a search for a few key words/phrases to find areas where I may be assistance. I the intent was to stalk/troll I would have done so in that thread. I only mention it in this thread to establish your habit of misleading people.
Now back to the swamping theory. I would imagine that after setting up dozens of giant scale airplanes with up to 13 digital servos in a confined garage that I may have experienced it once. I haven't. Perhaps during the thousands of flights in sports arenas around the country I should have experienced it? Can you imagine what the noise floor is during an NBA or NHL event? Still never an issue.
