RE: wanna see the inside of a lipo?
Had a similar thing happen with a NiMH pack, just not quite as dramatic. I crashed my Mini Super Sportster, and in my disgust (and ignorance), I failed to chop the throttle. Funny about electric motors...if they've got juice, they keep the torque on even if the shaft is stopped. The motor, broken loose from the mounts, twisted up the wires to the point that a short resulted; this resulted in one cooked 8 cell pack and a totally cremated ESC. I never knew until then that an electric plane could produce classic smoking wreckage. Live and learn.
