Maybe it's just too much circuit in too small a space. Switching BECs are quite efficient (around 85% depending on load), but there is still some heat there. Maybe the ICs being used don't like any kind of heat nearby, especially since the FETs are right above it creating more heat. Or, maybe there is some inductive noise coming from the coil that is inducing a voltage in a really sensitive area. Who knows? I'm sure it is possible, just takes some time to iron out. MGM has done it, maybe they should take a peek at one of those ESCs to get an inkling of how others are doing it. Maybe there's something CC is not taking into account that would be obvious once they see another design. Maybe use a whole different approach and use an integrated design similar to KoolFlight or WesternRobotics.
