FCC -

This interference can come from many sources - the biggest offender I see is the plane itself, especially on big birds. We are dealing with some kind of system to zap the spark plugs, which if it is not installed correctly, can cause heartburn. Have a part of that ignition system rub on something and you can cause more interfernece. Long leads can act as antenna and take garbage back to the receiver. Digital servos and large amounts of power going through the receiver can cause problems I don't think are fully understood yet - this is one of the reasons I use two receivers. Anywhere in your big bird that something starts vibrating - and our big ones can vibrate - you have the possibility of generating garbage that can affect you receiver. My perspective is to eliminate all potential sources in the aircraft and you have good odds that you won't lose your plane - unless someone turns on your frequency while you are flying. That has happened to me twice in 15 + years - cost me an Astro Hog and a Sukhoi. The guy admitted the Astro Hog and paid for a new kit - the scum that did my Sukhoi in slithered away - and the club that hosted the fly in didn't have the courtesy of saying they were sorry.
