Thomas: thank you for what you do, I understand it's a stressful job at times and thank you for trying your best to fit the situation. For all I know, the past two times I called could have been the same person. I just got a little annoyed when having to sit and listen to him rant without being able to speak up for a few minutes. I've only called twice in the past couple years (both were since the waterproof ESC's started coming out) but every time before that I had a great experience.

Bruce: Goh, why the heck would you even do that? That thing has way more than enough power for what he was doing to begin with... (he has more money than he does since apparently)

Arct1k: I am taking a shot in the dark, but my guess is that the bad solder joint causes more resistance on the battery end on the ESC resulting in a bad ripple current? I am also assuming that since the ESC couldn't produce it's famous sound because the FET's were ruined and unable to click on and off. And from my personal experience in trying to build my own brushed ESC for my electric bike, i'd say either the capacitance in the gate built up to blow them (I killed my IGBT for my bike this way) or maybe the ripple current killed the gate driver/microprocessor/IC chip or whatever chip is used to control them. Or at least this would be my understanding of what happened at this point.

Ksb51rl: Downhill is what I meant by unpleasant/less pleasant. And I actually did not receive the information I called for. After a couple minutes he started on ripple current destroying ESC's and after that I just said "good point, have a good day, bye". I did some extra research on components and calculations afterwards to figure out what I needed. I was just trying to save some time by calling and asking.

Castle's support group is very knowledgeable, they could definitely pass for engineers (assuming they aren't anyway) as far as their understanding on how the whole system works. The reason I posted this was to see if anyone else has had a similar experience to mine
