I got a couple of really cheap UBECs on ebay. Unlike other UBECs though, they have battery input wires that correspond to a Futaba type connector. I was confused at first, as I wasn't sure what to do with the third input wire (the white one). Doing a bit of Google research, it seems the white wire on Futaba type connectors is a signal wire. Therefore, this wire is redundant, right? The white wire on these UBECs goes straight through the UBEC's shrink wrap. I'm guessing I can remove the white wire altogether? Is that right?
