How many MMM's work and how many dont?

[slimthelineman]

yeah..... i dont know how this is all gonna turn out but seems to me that ALL MMM have had a lifespan of couple months at most (except briang's!!!). problem is looking like the bec is going out and disabling the controller. doesnt castle make a ccbec as well? why not use its design, or damn the bec altogether. i would rather use an external bec rather than have to ship my esc in every month. not an electrical engineer or anything so i cant really help in that respect.
