You do understand that the BEC is a component built into the esc; the use of a glitch-buster capacitor or an external BEC is only required if the built-in BEC isn't man enough, or doesn't provide enough voltage for a HV servo for example. I have no issues with the MMM's built-in BEC when using a pair of 1/4 scale digital servos in my TXT-1, or a single digital servo in my GorillaMaxx; I run a glitch-buster cap on each rig as a precaution, but no issues so far..
