Yes, you talk about blown caps due to over voltage, I talk about a dem-magged motor due to excessive heat, that then causes massive current draw trying to get the motor spinning; that much current will cook the fets.
Blown caps due to over voltage seems unlikely as:
A) Its a 25v esc, the caps are spec'd for 35v- I dont know where you're getting 40v from, but it aint happening. The voltage being put back into the batts as a result of regenerative braking is no more than a few mV, as proven by a nice eagletree graph someone did back along as a practicle test.
B) I dont need a B as my A was so great
The hot lipo packs would seem to support the 'massive current draw as a result of trying to turn over a dead motor theory'. Could be something else that is going pop though, but aparently castle (and HPI...) can access some sort of data recording chip inside the esc to do an autopsy....
