can an ESC kill motor

[Metallover]

The esc could probaby in some way short out somewhere that would affect the motors like at the soldering where the motor wires meet the board. Something like that should be pretty instant the first time you give it throttle or even when you turn it on. It could also probably send out the waves/pulses to the motor in the wrong frequency. If you don't know it, it's hard to explain but BL motors have to have the current delivered in pulses to each of the three circuts in order for the motor to run. that is why you need a BL esc to run a BL motor.

edit - looking back on this post I have complete confidence no one will remotely understand what the hell I am trying to say. Please do your best...
