how does that happen??

[JJVeld]

i was out bashing this morning. doing some running from my dog with the 3s and then it stopped. how do u fix this? just cut it off and resolder it? will it affect anything because it might not b able to supply as much current through a noobs soldering instead of a professionals

[Petertje60]

Every professional started as a noob. Just resolder it and do a better job than the one who did it the first time

[JJVeld]

ok ty for the answer. im not that bad its just im not the best

This is how I learned:

[JJVeld]

in the video it says not to use flux. the only solder i have is the resin core. squirrel makes it advanced. would normal soldering be ok?

[chilidillo]

My solder joints got better and now they're bright and shiny with no cold joints using 60/40

im looking for a solder article from rc car action

I use flux. Make sure you use a high temp iron with a big tip. The pointy tips don't hold enough heat. Make a jig out of wood, and I like to use a wooden clothespin as a third hand.

It takes lots of practice so do it on something cheap first. And have good ventilation.

couldn't find one yet

[JJVeld]

all i have is a pointed tip. i think its a 40w iron. i have done previous soldering with led lights and stuff so i should b sufficient

[50togo]

just heat it up good before you put the solder and you will be fine.and not too much solder don't go over the line!or you won't get it back in

[50togo]

here is a simple one not the best i have seen http://www.kingbass.com/soldering101.html

[Mossie]

just forget flux and get a good station and use silver solder

make sure you heat the object good and remember even i can do it

LOL

[JJVeld]

i got it done just fine. i accidentally did go over the line so i had a little filing to do. but its fine now and working great

Hmm, if in not wrong you need a little bit of flux to get rid of oxide and stuff on the surface, making the solder to stick better. 60/40 and 100w iron works everytime. 60/40 is used because it melts around 185 C, the other solders melts at higher points, making it hard to solder nice with regular iron.

You need to heat the area good, that right, but forget doing that stuff with silver solder and regular 40-100w iron, because those cant heat up the specific area fast enough and the cables will eventually melt damaging the cells inside. This will happen before the solder will melt nicely. Look a wiki for specifc melting points of different solder.

60/40 is a easy ticket to solder electronics.

This guide is one of the best I have found, and thats how I did my connectors:

I agree with everything in the video. Especially when he says "Aboot"

I do fill the wire cups in traxxas connectors with overheated hotglue. Holds the wires by their insulation, not metal, and holds well. Only make sure to heat it up really a lot.

[ttThree]

That is a nice idea, but it will be harder to resolder if needed, taking off all that glue. The reason joints brake is because people use wrong solder that is not totally melted while soldering (using a weak iron and solder with high melting point), or solder joints that melt due to high current. I also believe trx connectors are some how more tricky than deans, which are easy to solder and seal with shrink hose.

how hot does it have to be? because if its not done right, the heat from the current and resistance could start to melt it

How does that happen? Your dog bit it and it ripped. I've had the same thing happen. Lucky that's all the damage.

nope she didnt. all my dog does is get the body so theres little teeth indents on it but its not noticeable with all the scratches

[joe831]

Hmm, well then what else could have happened? Both of my trucks had the wire ripped off the ESC board, and the only thing I can think of is the dog catching it in her teeth. Both ESC had to be replaced, and one caught on fire due to the ripped wire!

[JJVeld]

it was just from wear and the bending of the wire, creating a weak spot in it right next to the solder, where there wasnt the tubing around the bare wire. if u look close u can see the part of the wire in the pic

[ttThree]

Thats why its good to bend the wire a little bit before the soldering joints or connectors to prevent damage.

Best tutorial i've seen! They have 9 videos I think! http://www.youtube.com/watch?v=vIT4r...feature=g-hist http://www.youtube.com/watch?v=Mrhg5...feature=relmfu
