You are right on the money on this one Thi, that is where I'm getting the most coupling.
These kinds of problems can be hard to hunt down
This i know now.
Glad to hear you are making progress. You have two systems to isolate: Your (1.) ignition system with its own battery and switch, and then your (2.) aircraft control system. You want to keep the wires and components as separate as possible between those systems. That engine cut-off unit makes that tough. You also want to try to make your ignition system as quiet as possible, and that is where the copper strap comes in.
Also.... Your aileron leads being long make good antennas and you might try twisting them rather than having them run straight. That was on old trick on television twin lead to antennas as if you run that straight, passing cars would cause noise on your picture. Twisting it allows it to isolate the interfering signal electromagnetically.
Don't rule out the vibration factor quite yet as I can see that is plausible.
