Not to revive what is already an awesome sticky.

Tip Tinner renews the plating on tips. So as long as you are proactive your tips should not ever wear out no matter what company makes them.

solder suitable for comm tabs, silver solder 3% plus, small scale brazing skill a plus.
A minimum of 450F melting point on a 10 turn brushed.

Motor commutators, I am giving up some of my old secrets with this one:
Kester Aquabond paste or solid solder. Use no clean flux, the paste if you are lucky to find doesn’t need flux.

With the paste you you will need a small butane torch, with solid you will need a 70 watt plus iron.

Kester aquabond has a melting point of 495F

Never wearing out is a stretch, but you can make them last a long time.

The plating is going to react to the solder and O2 in the air, just at a slower rate. Keeping the tip clean, tinned, and at reasonable temps slows down the process.

One should not ever drag solder either.

Not sure it's posted in this thread, but in a pinch you can make soldering iron tops from solid copper wire. You can make custom shapes and what not. They work great.

Default Soldering the ESC to the motor without touching the wire?

Hello all,

How do I solder the ESC wires to the motor without touching the iron to the wire? There does not appear to be enough room under the 3 platforms to place the soldering iron.

Specifically I will be soldering to this motor.

Thanks.

Ypu solder to the outside... It looks like the silver areas are the solder pads, exposed and easy to get to.

To expand on what was said above, you just need to pre-tin the wire, and the terminal which looks to be done already. Then put a little tin on your iron, and touch the iron on top of the wire pressing down onto the terminal. The heat should flow with the solder on the iron, it'll heat the wire, then it'll heat the terminal.

I feel like this would be pretty bad QA fail.

in my opinion all the joints looks kinda questionable for professional product, but thing that stood out is it looks like flux residue was left on solder joints from 3 main wires.
