Dragonfueled: how was your car geared? from what I understand, smoke and flames is pretty much always bad setup.

For starters A 1y on 4s is running quite low rpm, and you would have to gear it quite a way up to compensate.

coolrunnings: in the billion or so reports I've read of dead MMMs I'm yet to hear anyone mention a dead lipo, my guess would be no. In the fire and smoke death scenario, perhaps it shorts for a split second from the initial component failure, but the onrush of current kills everything else and any chance of there being a short.
