Now that you mention it: mine also doesn't have the copper wire (just copper painted resin). The first version of GG's arcs did have this. Since my front part needs replacement anyway, I'd appreciate it to also have the copper wire front, like pictured in the first post. After all, that's what we paid for, no? Alberto seemed to got the copper wire version (see his pictures).
UPDATE: I see that my payment for the reactor will passes the 45 days where within I can file a paypal claim within a day or two. I very rarely do this with purchases on the RPF, but just to be safe, I opened a paypal dispute. Just to ensure this will be solved.
