I have a question which really seems rather basic but has not been talked about very well. Does it really matter how far away your receivers and wireing are from the ignition if you have a secondary ignition failure such as a bad wire or imperfect connection of the end cap and plug? Since a lot of electromagnetic energy is caused by imperfections in the secondary ignition, I've always thought that distance does not matter when you have a secondary ignition problem. Interference is interference, no matter if your radio gear is 8 inches or 8 feet away from the interference source. I've seen installations where throttle servos are placed right next to the main ignition box, suxh as on one of the BME Aircraft Ultimates a friend of mine is building. Then the Composite-Arf models seem to encourage a very far forward location for the throttle servo as well, which is right against the back of the motor dome on their Super Extra. It just seems that if this was a really bad problem, the aircraft makers would not be recommending putting throttle servos there.
