Can someone possibly help me?
Okay so I thought I had my esc wires all soldered up to the brushless motor solder tabs I ran it once went fine till tires blew, changed tires and rims ran second time and wires blew off of the motor solder tabs. Can someone help me and explain a good way to solder?
I'm using a Tekin T8 motor.
I'm thinking I need to get some flux....Does this look okay?

I've seen that and it doesn't explain why my wiring is coming apart on the motor solder tabs...
Do I need flux?

Most common mistakes:
Not using flux, doesn't take much (or using the wrong kind, plumbers etc).
Not pretinning the tab and wire with some solder. A little flux here too doesn't hurt.
Also it is very important to not let the connection move after soldering as it hardens. Don’t blow on it either, let it cool naturally.
Possibly wrong solder or too old solder. (again, this ain't a plumbing job)
For long term, avoid corrosion, be sure to clean the flux off (somewhat dependent on the exact type of flux).
There is a wealth of solid info on the sticky at the top of the page of this section, much more complete than the video (as I remember it from some time ago).

Thank you I am using 60/40 rosin solder and I just ordered some liquid electrical flux that I listed above. When I try to coat the solder iron tip it just drips to the ground never stays on the tip end

The soldering iron tip is dirty. Run some steel wool over the tip while hot and then add some flux to it. It should look nearly as shiny as the solder then and should work well for you. This is also key to good heat transfer as a cold solder joint will fail rather easily.

Okay, I'll try some of that in a bit...Makes sense though what you stated.
I'm running a 1550kv x 5s system and it is pure monsterous! OMG

Hi all, update. Got everything soldered up good to go. I'm using a 60w iron and I got some Kester 951 Flux off ebay that helped tremendously!
Thanks all
