Here is my interpretation of the KO static fix mentioned earlier.
I hope you can make it out. Basically I have fitted cone washers upside down in the countersunk holes, with round head screws through them to grip the wire. The wire is some thin black bell wire from Maplin (bought a long time ago), which has had the ends tinned to stop them breaking up (untinned wires were damaged by the screw thread). The cone washers are by Jet Racing (#JE-43P). Unfortunately these are not available in Tamiya blue, I used some purple ones I had lying around. The screws are Much-More stainless steel ones, M3x12mm round head (#MSR-312). Jet and Much-More products are available in the UK through www.muchmoreracing.com.
