Help.. BL setup issues (fried ESC)

[xcntrk]

What the heck is wrong with my BL setup??? I recently converted a Tmaxx over to electric and have a whopping 4 runs with it so far and believe I just fried my ESC...

I run a 7XL with MM on 4S. I’ve been having issues with the 7XL running super hot and captured temps as high as 220F before shutting it down. I thought I was undergeard a bit (51/20) as the MM was only running around 100F and batt just a few degrees above ambient.

So I just received some additional spurs and changed over to (46/20). It seems I went too far in the wrong direction as the MM thermaled twice both times around 175F and the 7XL still runs in the 200F range. It’s been cogging pretty badly on initial throttle now too.

This last run ended with me standing over the truck, body off, taking temps and investigating the cogging...when...the ESC “sparked” and released a small puff of magic smoke. It was literally 1~2 seconds before I got the batt disconnected since I was right-there, and definitely wasn’t a major melt-down. Also one of the 3-motor wires pulled from the board. This may have been the “spark” and smoke, but not sure until I attempt to solder back on and see if it works. But it was hot, at least enough for a wire to un-solder and pull out...

So what gives! I’m pretty disappointed with my setup. It’s got crazy power but so far I’ve yet to get a full run in without overheating the motor, and now ESC.
