andreazinno, I wouldn't cancel any orders just yet. There's got to be a good explanation for why it let go...
I've been going over and over this meltdown in my head (slept like crap last night).
I'm hoping that a talk with tech support and a thorough investigation of the dead XL will pinpoint the issue.

I decided to pull back the remaining plastic end cover, the one where the battery leads go in to have a closer look. Hands still smell bad from last night, yuck.
The fet board it completely separated and only held together by the capacitors and it looks like several banks of the fets have exploded, others are fine.
I assume this means that one or more of them were not switching off properly.
The control/BEC board looks untouched on the top, and without disassembling it further I can't see the bottom side of it very well.
There does appear to be a lot more solder on the pad for the positive lead than there is on any of the other pads where the wires attach.
Makes me wounder if maybe the positive lead was able somehow to come into contact with a circuit on the control board due to a bad solder job???

I've got to think it's human error somewhere, a design flaw shouldn't have made it this long.


If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
