Default Solder Help Please

Ok, I just bought a used xxx4 off the bay. The motor is hardwired. One of the leads came off the motor. What would i use to clean the lead and the motor tab so I can try and solder it back?

Also the esc has deans but all my batteries have regular tamiya type plugs. Can I just cut the deans off and get connectors to place on the wires? Can I cut the wires down some without losing alot of effiency? I prefer to stay with the tamiya type plugs because its easier for me. I can change one plug versus changing 10. Thanks for the help.

Do you have a soldering gun? I would just stick with Dean connectors.

To clean the connection I would start with buggy blast/motor cleaner, or just rubbing alcohol and an old tooth brush. Then dab with a little bit of paste flux and heat with a soldering iron. Now your ready to re-solder the joint.

BTW I agree with the above. Switch to deans if you can. Tamiya plugs are very inefficient. By switching you will most likely notice more power and longer run times.

Once you have the crud cleaned away, get some desoldering braid and clean off as much of the old solder as you can before reattaching the wire.

On the plugs, if you are running low wind mods you risk melting the tamiya plugs, or worse catching someting on fire. I've seen both happen when running mod motors with tamiya plugs.

Soldering Gun's have a trigger that when depressed the iron portion heats up.

Soldering Iron's heat when pluged in and cool when un pluged.


Both irons and guns will work for soldering or de-soldering.

Like I mentioned eariler get your self a good soldering gun to start with.

Not quite sure what your getting at.

See the above post on soldering Guns. Flux is not for de-soldering, it is to help the solder properly adhere to what your working on.

I dont think your being constructive, I think your giving incorrect information and " the info your giving aint better"

if you re- read avrcguys post he said - Then dab with a little bit of paste flux and heat with a soldering iron. Now your ready to re-solder the joint.

There is nothing there that says use flux to desolder.

Like you were trying to, I am just being constructive.

While it's strictly a matter of personal preference, I much prefer a good iron to one of those guns. Having tried several irons and a gun I've been very happy with my Hakko 936. The ability to change both tip size and heat makes it good for everything from building battery packs to replacing wires in ESC's and servos. I have an old Hobbico 65 watt iron with a huge flat tip I will break out if I'm building lots packs at the same time, but otherwise the 936 pretty much takes care of all my soldering needs.

As for using flux to desolder.....If the solder is old or gobbed on real heavy, a touch of flux will help it melt faster. The main function of flux is to accelerate heat transfer so it's useful any time you want quicker heat on your joint.

I have had both, have that Craftsman Solder Gun now, because when I had a iron, I sometimes forgot to unplug it!!!!!

With grandkids and dogs there could be burns (this can happen with a gun also) AND burned down like my house!!!!!

So that is the why(s) of my personal preference!

Did you not have a stand for your irons? When I was using straight plug in irons I had a little wire stand to keep them up off the table and safe when in use. I got it at my LHS for around $3.00. The Hakko comes with a nice heavy duty stand that also holds a tip cleaning sponge which is one of the features I bought it for. Although I don't do it, it can also be left on for extended periods without being used and not burn out like all the other irons I've had. when I was using the gun I had trouble with small wires and doing things like replacing servo leads, or the outboard connection wires and switches on ESC's without making a big mess. Thankfully most newer ESC's have built in on/off switches, or at least a plug on the case to connect the switch to which makes it much simpler to replace. Same with the battery and motor wires, instead of being inside the case and right up against the rest of the circuit, the board has been extended outside the case for these wire connections making it much simpler to replace them.
