Chakster, To create a "resistor" using copper wire is folly, don't you think? Even fine copper wire has very low resistance per foot, because it is.... a great conductor. You'd need miles of good copper wire to create a 47K ohm resistance, for example. I suspect there is some other kind of wire used in there, like nichrome, which is popular for resistors because it is a bad conductor. As to the lack of inductance, there are very fine non-inductive wirewound resistors, made by Mills and probably others. But even those are not totally without inductance; the wire is wound so as to minimize inductance, but I think there will always be a tiny amount of inductance in any wirewound resistor.
I looked it up for fun: 1000 feet of 30 gauge solid core copper wire has a resistance of about 100 ohms. So you'd need ~470,000 feet of it to create a 47K ohm resistor. I don't think that would fit into the ZYX chassis.
