Do I Need A BEC?

Not that I can see. As long as the voltage is equal or better than the originals, they were soldered correctly, and they are truly low-ESR types, it'll be fine.

Thanks Brian, yes im pretty sure all specs are better than originals, this is the one i used

I've just ran it today with Neu 1515 1Y and the temp at end of run after 15 min is about 145 on MM heasink and im geared 22/62, Neu got to 152 though, looks hot for Neu but i was told as long as I kept neu running below 175, it shouldn't be a problem. Would this be a safe setup to be continue running or do you suggest I gear down a bit? i was running 22/68 before but felt I want a bit faster. I also have a 1.5D comming, im wondering if I gear for 45mph, about the same as 22/62 on 1Y, would it make things run hotter or cooler? running strictly on 4s only

Yeah, your motor temp is "OK", but I'd regear to get lower temps if it were me. I'm surprised though, I've geared my 1512 2d on 4s really tall and it never got more than warm.
