And, my only point in asking for that info was to mention that despite any mfg listing the "working temps" (if they ever listed such a thing), the questions still get asked for nearly all, if not all, mfgs out there - period. Just because ANY type of info is posted or listed by a mfg doesn't mean the end user is going to go out and look for that data - even if it was the "right" data.
You guys realize that the lowest temps mentioned in either of the links is 150C which is 302F. If that is a working temp, it would melt the canopy.

302F wouldn’t melt a canopy. Mainly because they use a thermoset resin that would decompose not melt. Look at the temperature listed on your JB Weld, mine says 550F. Granted not all epoxy is a good as that, and certainly most canopies aren’t made for heat resistance, but their not in intimate contact with the motor either.
Your ESC doesn’t have an operating rating, just maximums. Sustained and 5-15 secs peak maximum amperage rating.
The peaks are just that the maximum the motor can withstand without damage. Demagnetize the magnets, or melt the insulation off the windings. Nobody is measuring a ‘real’ temperature anyway. Best that’s being done is pointing a IR thermometer onto the can or in the vent holes trying to get the windings some time after the motor has cooled. Take the temp as fast as you can, then count to 30 and take it again. It’ll be drastically different.
Think of this, if you don’t remove the enamel from the motor wires, molten solder isn’t hot enough to damage it. Windings need to get pretty hot to damage them.
Maybe someone should put a thermocouple buried in the windings and an Non-contact IR thermocouple pointed at the can to get a ‘real’ measure. Until then all you can do is take the provided values as a guide and assume some reduced value for a limit from there.
