No you were specific enough. The actual Bloomberg article is different that your blurb.

The motor controller is a 3 phase H Bridge so if one phase fails the other 2 bridges burn out in rapid sucession unless they so overbuilt the power circuits that locked rotor conditions do not result in immediate over temp junction failures, OR, they are running brushed series DC which will overspeed on failure of the power circuits. And you have one set of these for each motor, once again unless they are doing massive shortcuts, because motor control gets squirrelly running two multiphase motors off one ESC. I could see the fireball scenario on over specced controllers or battery shorted conditions. Just like Volts catching fire when they get punctured and flipped over then sit in an impound lot for a week.

Something don't pass the sniff test. And they fly like aerioplanes, you dont switch from flight regimen to another, you gradually change it.
