Ummmmm.... Yup... the ESC Let go...
Guys... the "6S" claim for these boats is for a FACTORY, unmodified prop, which slips and cavitates and ventilates and doesn't "hook-up" very hard.
If you are going to turn an 1800KV motor at 40,000 RPM (yes, I've been reading with some puzzlement on that other thread), you cannot expect to be able to run the same props you ran at 26,000 RPM. Simply won't work. Loading is NOT linear.
That "cupped" part is likely what did you in... I've beat the HELL out of an IM31 on 6S with the factory power system and have never had an issue with heat or anything else, and that was using the stock 4mm contacts. However, I'm running appropriate props. Either a stock prop, a standard prepped stock prop, or a nicely prepped, Prather 215. I've also had good luck with a rather standard ABC 42x55...
