I'm in the painful process of soldering extentions on 4 servos for a glider...having some difficulty working with such small servo wires. I'm able to pre-tin all of the wires, but then when I try to get them together it's always a mess and I end up with a huge glop of solder. I don't twist the two wires together, simply lay them on top of each other. I do have the helping hands tool to assist. I think the 70w iron is too hot for such small wires.

Any tips would be appreciated.
