There are a bunch of different approaches to rigging.
I used two types of materials for rigging my 1/74 scale MB-2:

.
The control wires are very fine wire I salvaged from a ceiling fan light switch. The rigging wires are smoke-colored invisible thread (I think it's actually nylon, sort of like monofilament) that I got at a fabric store.
What I did was drill holes part way through the underside of the upper wing, and the whole way through the lower wing. I then anchored the invisible thread in the upper wing with super glue, which I then sprayed with a quick hit of accelerator. Then I would thread the "rigging wire" through the hole in the bottom wing, but a little tension on it by clamping it with my reverse tweezers (they are squeezed to open), apply super glue, and accellerator.
Then I'd repeat for freaking ever.
Actually, with the help of a ballcap with LED lights in the bill, I was able to do four or five wires in a half hour or so.
If I were using wire instead of thread, I'd probably use the same approach with drilling blind holes in the top and full holes in the bottom. If the wire is thin enough, it can be gently pulled taut almost like thread.
