Wow, so MTronics finally made something new. Just looked up the spec on the beast version for 1/8 r/cs; average to poor at best:
12nimhs / 4s lipo max
Rated current 150amps (good if true), peak current 200amps (poor, looks like airplane esc fets maybe?)
BEC rated for 5volts & 3amps, only for use upto 9.6v input- lame.
Its pretty compact and waterproof, but only much good in lighter stuff with an external BEC
