Home Built UBEC

And you generally don't parallel regulators, but use a higher power/current pass transistor. But no matter how it's done, a linear regulator is inefficient, especially as the supply voltage and load current increases.

That said, a linear regulator works well in the 2s (maybe even 3s) or 6-8 NiMH cell range. Since the voltage is so low, efficiency is close to a switching UBEC.

I decided to go with Castle Creation's BEC Switching Regulator on my E Revo.

It looks like a pretty good setup. On 4S Lipo, it should help to take heat/load off the ESC even after I install the 125 Amp Monster Pro.

Anyone had any experience with this one?

I know JohnRob did a pretty impressive video with it.
