Should a run a BEC?

[BrianG]

The Novak system has the BEC hooked to one of the two series-connected packs. As such, it isn't really affecting efficiency that much at all, but having one pack drain more than the non-BEC pack will cause uneven discharge, which is a big deal with lipos. That said, if you are having problems with the stock BEC, chances are it's being overworked and could benefit from an external UBEC (or receiver pack for that matter). Whatever you decide, it would be advisable to hook the UBEC across both packs at once for best efficiency and even battery drain.
