I was thinking of powering my servo off an external BEC or from the battery (connected to 2cells). Do I pull only the Power wire out from the 3-pin connector and connect to the positive of BEC or battery or pull both the Power and Return/Gnd wires out and connect it to the Power and Ground wires of the BEC or battery? Or is there a different way?
My servo's rated for 6-7.4V and my ESC's BEC only puts out 5.75V/3A, so I'm thinking I can get some more torque and speed if I give it 6V regulated or 7.4V unregulated.

Thanks.
