UBEC or BEC? And Witch One?

[BrianG]

I'm kinda partial to the KF one. Yeah, it's bigger physically, but that's what I like about it. If a UBEC output is 6v @ 3A and operating at 80% efficiency, that is still 3.6w it has to dissipate. For that you need surface area and the KF one is large enough to really help with that. Add to that the fact that we generally beat on our electronics and overengineered products last longer. Just my $0.02...
