IMO Run with ubec if thats how it worked - when CC release v2 whip off the BEC and see what happens... that way you won't be out of a controller for too long in case anything goes wrong
you think????its mean that the esc have the same risk of failure if i run without the ubec...i think that i was clear of problemif i completely understan if i buy a first gen of mmm its really better to use a external bec??
