RE: Running Servo Wires through wing??
For the last 4-5 years of assembling ARFs, I haven't used anything. It's been fairly easy to hold the wing vertical and let the wire work it's way through. It takes some wiggling but hasn't ever taken more than a minute or two. Once you get the hang of it, it's fairly easy. Some of the better ARFs have string in place to pull the plug through. In this case, you get more than you pay for.
