righto, bit of an update; including this post I’ve found 6 examples on this forum of Uboxes catching fire, plus frame found 1 on reddit and BB added anotther. List in wiki below, add at your own convenience
@vegr0 I don’t know much about the stormcore issues, similar to havenever I’ve heard through others that the 100D had a reputation for bad reliability but I’ve got nothing to back it up. For what it’s worth I came across 1 maybe 2 stormcore fires in my search for spintend ones, though I don’t know if they were 100D or 60D, and I think stormcores are a lot more popular so that’d be an even lower failure rate per unit sold

thanks for doing a search! a bit concerning that so many of the fires were of an unknown cause 
also realizing now that I’ve got a ubox v1 without the foam “fix”… been riding it for near 1k miles without issues… maybe I’ll reach out to Spintend and get some of that foam

yeah lol it’s not great, it’s weird that 5 of the 6 were this year when the device came out quite a ways back. Maybe there were unreported ones in the long gap or something changed in production

those are all already accounted for in my list above, except the reddit one. As they appear in the screenshot they’re Jarn’s single four times, shua, cake-brief on reddit, next row is cake-brief again, product shot, a different shot of skyart’s one. Cake-brief is the only new one to the list
all i know is that, i will never buy spintend

My ubox v2 75 went up in fire, early this year from 5.3 firmware

Same for my tb6 and flipsky 6.6
Its absolutely stunning this can happen and it gives me 0 faith in the VESC project.
It also baffles me that people call other escs used by chinese brands “hobby esc’s” Implying they are not good enough. Man wtf i just did motor detection with the latest firmware (as they advise) and the friggin thing exploded, wtf kind of hobbyists are implementing this.
Imagine if phone updates did this or windows updates.
/end of rant.
Its christmas now and time for forgiveness i guess 
MERRY CHRISLER EVERYONE

VESC project cant be responsible for other people/companies designing hardware… if this was a trampa ESC thats actually verified by the creator, you have the right to say this tho. (not saying trampa hasnt had troubles)

Quick update to my case. I believe 1 or 2 of the fets blew which were right under the phase wires where the hole is. So to my understanding, voltage or amperage spike due to hitting the bridge extensions?
…or soldering heat damaged one or more FETs, causing at least one to pop when stressed.

or inadequate soldering/heat maybe? 
those SMD power fets can be tricky…
Fuk yeah i did… hit motor detection, and then it did the big woof

I haven’t seen reports of issues since they cleared up the firmware mess to be honest.
From what I gathered VESCTool showed the default firmware as applicable/uploadable when it should not have… which caused some of the issues we’ve seen.

Oof, that brings us to double digits. Will I link this post here as the reference or did you post elsewhere that I didn’t find? Hope you didn’t have anything else burn up as a result, also cheers @glyphiks
