Need response from a Castle tech for MMM question

[BrianG]

The MMMs with melt down is far less common than the ones with BEC problems. Generally, the ones with BEC problems can be fixed with this mod.

Using an external BEC is all fine and good, but if the internal one goes south, the ESC is dead, even if the external BEC is still perfectly fine. Since we don't know exactly what causes the BEC issue, so using an external one (without disabling the internal one) may not help at all.
