They key to soldering is flux. I just use the same flux you use for copper pipes from Home Depot. You will have a hot soldering iron. I also picked up a Weller solering iron from Home Depot for like $13. I got the 35w iron with the screwdriver tip. The key is to have a hot iron with a decent size tip. I also have a 25w Weller with a smaller tip but is quite hard to solder anthing in rc since the wires are a heavier gauge.

The hardest thing about soldering is holding the wire together while you are solding. You only have 2 hands. lol I use a pair of hemostats clamped on the wires to hold them together. You can also use aligator clips to do this but they may not hold as tight. I apply some flux to the bare wire, but the soldering iron on the wires, let the wires heat up some, and then touch the bare wire with the solder. You will want to coat the bare wire completly. Now with the soldering iron still on the wires take away the solder, wait 4-5 seconds, and then remove the iron. If the solder looks really dull and pitted when you are done you have a cold solder joint and should touch it up a little.

Another good thing to do is before you solder the wires together you should tin the tips of each wire. That just means apply some solder to each wire before you put them together. That way once you clamp the wires together and heat them up the existing solder will heat up, melt, and bond together.

Hope this helps.
