Then there was me who broke all the rules and got away with it for a couple of years, THEN GOT BIT IN THE BUTT!! I have mounted choke and throttle servos right next to the ignition without a problem. Then the last big plane I set up I tried to get away with my old {wrong} ways and had so much RF I couldn't have ever flown the plane. I had to completely change the set up the correct way {normal} and I was still getting bumped a bit. I ended up moving everything back 2 feet away before I got that plane off the ground. Sometimes you get the Bear and sometimes!!!!!!!!!!
