RE: Name & Source regulator down to 6V Lion use?
I used two different ones depending upon the size of the plane.
The [link=http://www.hobby-lobby.com/ubec.htm]KFS003[/link] UBEC has a 6v output for 3amps continuous and 5amps peak.
The FMA [link=https://www.fmadirect.com/site/fma.htm?body=Search_Results]VRLI2[/link] Power Force Regulator provides 6v at 10amps continuous for giant-scale applications.
