I guess my question is; what about the MM is "K.I.S.S."? The only difference between the MM and MMM/Tekin design-wise is the switching BEC. Yeah, the big guys handle more voltage and current, but that's basically just component choice and number; the power component layout and brains board are the same. And since running the linear BEC is the MM is too inefficient, we run external switching BECs anyway, so the BEC difference is moot. Call me stupid (please don't) but I guess I just don't get it.
If the question is why the MM works and the big boys don't, the only reason I can figure is the MM has smaller wires and designed for lower currents (traces are smaller) so there is more wire resistance limiting the current somewhat. Personally, that's not the best way to make a setup reliable.
