First - don't be trying to solder any of the wires on your heli with a big Weller 100 watt gun style. You won't be able to do it.
Get a small pencil iron. No more than 60 watts - max.
Radio Shack has a "starter kit" for $12.00

Second - get "rosin core solder". The smallest diameter they sell. Not the huge stuff from Home Depot for plumbing.
Rosin is flux inside the solder. It helps deoxidize the copper as you solder.
Get leaded solder if you can find it. It's much easier to work with than the lead-free: http://www.radioshack.com/product/in...ductId=2062719
(you probably won't be able to find leaded solder in Europe).

Let's assume you're soldering two wires together.

"Tinning" means getting some molten solder on to something - either the soldering iron tip, or the wire.
You want the solder to "plate out" (coat the surface like paint and fill in between the strands).
You don't just little balls clinging to your work. That won't work.

1. Get the iron hot (should only take 2-3 minutes).
Make sure there is some solder on the tip.
Clean it with a damp sponge (while hot).
"Tin" the tip. Which means adding enough solder to coat it and make it shiny.
Wipe it again on the sponge.
Repeat until it stays shiny.

If it's really tarnished (it's probably copper). You may need to clean the tarnish off the iron before it's usable.
You can use sandpaper or a...Continue Reading
