The problem using something rigid like epoxy is you are just moving the stress point further along the wire.

If it is true about a yellow mark was indeed on the esc part, that opens the possibility the failure was my fault and would have to be from too much heat at the time of soldering that wire. Nothing else would make sense in my opinion. So if I actually was the culprit, this is why I now would like to focus on reducing vibrations at the point. especially now that I know just how sensitive to heat these wires might be.

When I researched a few months ago, about building motors, the builders described the need to keep the insulation tight to the solder ball. They were saying even an 1/8"+ of the wire exposed would fatigue and break at that point. In what amount of time I don't know. My "old" original motors are that way, very little exposed wire.
The motor builders were obsessed with vibration. Even though the winding wire is coated with a dielectric film, they would pour an epoxy over the windings to prevent the wires from abrading each other. We are talking big RC plane motors that are expensive.
