And thanks for the hook up. I noticed the package Dave . I see the one Al posted is a blue package. I got to read it closer to see the difference. I haven't ordered it yet. Going to do that now actually... well I believe the blue and green packaging is the same. They have the same part number and I looked them up on the web and I can't see any difference in marking

Just ordered some. Not bad for $7 off ebay.

Al's might be the same.
The ones I ordered in the past from Goot wick, that were a different color label, had a steel
braid covered in copper. Price is very reasonable for the braid and a real bargain for
the performance gained on certain chassis.

As ugly as my braid work is my first attempt at shunts is much worse.....

Did you pre solder the shoes and chassie. Also another thing that helped me was just melt solder on the iron and use that don't try to hold the solder roll. I pre solder the wire end to.
Just hold it a couple seconds then go back. Remember your doing an electrical connection not soldering structure. Hope that helps you out. I was just doing some.
It doesn't look like you sanded.
Sand the area before you solder it to.that makes a world of difference. Just a touch of flux

much of what Sam says is good.
I like to clean the metal with an abrasive, sand paper or a cut off wheel in a dremel before soldering.
tin the shoe and the other plate on the chassis, very light coating of solder.
clean that again, put a little flux on.
no need to tin the braid or shunt, they want to soak up solder and you can get too much on.
get a little solder on the tip of the soldering iron, I like chisel tip rather than pointed, put the braid/shunt on the spot you want to solder and apply the little bit of solder to the braid/shunt.
abra cadabara, nice clean solder joint. clean everything real good with lighter fluid and/or electrical cleaner like the Radio Control guys use.
something else I noticed, and this seems to be a lot of guys, using really thick shunt wire. totally not necessary, much thinner shunt will work just as good.
consider the gauge of the wire on the armature ..... the gauge of the wire on the resistor in the controller .... bigger gauge wire than either of those is surely providing lots of conductivity, but is it overkill?
