I will say BK sales people are not correct...

If BEC on MGM controller outputs full battery voltage, then BEC part is damaged. See my earlier report on MGM's BEC failure.

As far as updated versions of MGM ESC, I haven't had such problem yet. But I was not using BEC from the very start either (memories of blown servos...).

You should be able to apply brakes as long as you want, motors back EMF should be well below FET's voltage limit. But if you have noisy/glitches in receiver part then you signing for disaster yourself. Use good power connectors and good UBEC (most times bad capacitor on UBEC or ESC part can create problems).
