As far as the wires desoldering themselves, can't a different mix of solder be used to increase melting point while retaining high conductivity?

Yes there are ways to get wires better connected. Two of those appear in my mind.

1) Pb free soldering. The special Pb free solder contains silver and does have better conductivity than old/normal 63%Sn+36%Pb solder alloy. Also the melting point rises from 23x to 27x degree Celsius. This solder process needs more heat and skill to be done well, especially by hand.

2) Copper welding. It actually let the stiff coil wire and the flexible silicone wire to melt together and then cool down. They become one single piece of copper after the process. You can imagine how tough it could be. I believe this is the ultimate wiring solution for extremely high power density RC motors. But this process generates high temp over 1100degree Celsius and must be done with an anti-oxidation environment, not sure how this can be done within such a tiny space in motors like the 1515. Also uncertain is how much would that process cost.

So most RC motor manufactures choose to leave this issue to the user: Look, we run the coil wire out of the motor, you do the rest work, if the solder joint desolders itself, that's your problem. Castle, again, doesn't follow this philosophy.
