MM Pro BEC updated?

[SpEEdyBL]

My current MM Pro that I bought a couple of weeks after the release date seems to have what I would describe as a weak BEC. When using it to power my JR9100s servo, the LED on my AMB transponder flickers when the servo is moving and shuts off completely with additional load. I put a Novak 25v 2700uF power capacitor across the battery slot of the Rx. It reduced some of the flickering, but that's about it. I've set the BEC at 5.0, 5.5 and 6.0v using 2s and 4s packs for the main power with the same results. My MMM never had this problem. And for the info, the esc only rarely shuts off for a split second at most.

My question is, has the MM pro bec been improved or is it still the luck of the draw if I buy another MM pro? I know other people do not have this problem with the exact same setup.
