I contacted a gentleman about resoldering the 3 wires to esc. If you leave solder on the esc and pre-tin the 3 wires prior, you can make it work. Now if you take all the soler off the esc and try to solder the 3 wire back on, it's a 100 failure. I tried and the green material came off th esc which means , you can throw away the esc as there's no way to solder it. I've tried soldering on several escs with same results, it's in the board material. I tried all kinds of solder from silver to plumbing and solder from Iowa, no luck.
