...I talked to Hitec, and they suggested using 1) twisted wire, which I am not, and 2) putting some ''ferrite rings'' on the wires to help with interference. I found some on Tower, but they were discontinued. I'll be ordering the twisted wire, as well.
I can't believe this kind of problem still exists in today's world. This sounds like 30 years ago. Anyway, you don't have to replace the servo leads, just twist the ones you have. But, As others have said, find the problem, don't just jury-rig a fix. JMHO.
