I finished soldering deans plugs on my Stampede, charger, and batteries. I did it right. But on a few connections I think the metal wire and the metal bit from the deans plug aren't quite touching. Instead there's a layer of solder between them. Will this affect the electrical flow or will the electricity go through the solder material the same rate as thru the wire and metal?

Solder is conductive just like the wire that it's attaching. That's its beauty.

Excellent! I'm all set then. Thanks. [8D]

Unsolder that wire and make sure it making contact with the copper on the plug.
What I do is rough up the shine on the plug terminal then use a short thin piece of bare copper wire and wrap it around the heavy wire to hold it in place and it becomes a part of the joint.
The difference between the wire and the connector with solder in between will make it act like a resistor

Solder may be conductive but it wasn't made to be used to fill an electrical gap.
One day he's going to be flying and that joint will develop a crack and his heli will fall out of the sky.
The picture shows a good solder connection joint.

Okay I'll keep that in mind. It's actually for my Stampede truck, not a helicopter. If I ever get into helicopters or planes I'll be sure I know exactly what I'm doing including soldering and electrical works.

I drove the thing and it's fast as heck now. No stuttering or anything like that. And I did scratch the surface of the metal part of the plug before applying the soldered wire. I used a hobby knife to make criss crossing scratches on it.

OK,
I thought it was for a Heli.
Anyway when your pulling amps you can't make a joint good enough.
I noticed on some of the smaller ESC units they have those thin 2 pin connectors and they get hot because they can't carry 10 amps.
The Falcon I fly draws 14 amps and comes with a DINS plug.
I think those R/C cars draw a heavy load. 37 amps wide open?
I can't believe how realistic they make those cars and trucks.
My friend has on and that sucker MOVES!!!!!!!!
I wish my station wagomn went that fast[]
GL on the racing.

Thanks and thanks for your help.

You joint with a bit of solder between the wire on connector will be just fine. It might increase the resistance by 1 ten thousandth of an ohm (a negligible amount) but probably not even that much. I doubt that anyone on this site has equipment pres ice enough to measure the difference and certainly your motor will not.

Sounds like your joint should be fine..

However, in the future.

That may be a bit true but what i'm getting at is that it is not an industry standard acceptable solder joint.
Inform the person how to do it correct and not say that's close enough.
I take pride in everything I do.
As the saying goes, Do it right and do it once.
Vegas/ PS:
The resistance depends on the type of solder used.

Yeh, it's really easy to get a cold joint..

I thought a proper connection required mechanical strength, for example, a crimp to take the strain and solder to provide electrical conductivity.
Therefore Dean's connectors are not the best for the job.
Maybe something like Anderson Power Poles would be better.

Just a thought.
