Kerry, I'm using very thin copper wire of around 0.06mm (measured) out of high flexible silicone cables, like this:

There are many very thin wires in. Real copper without paint on it.
Usage as ignition wires in 1:48 on my engines, see actual project:

Finally fixed the bugs I was having problems with. Now it is the Blackhawk.
