So is the power to reciever, as shown on the schematic, delivered thru the cable from BEC ?
Aloha, once more, Les
Yes, the center conductor (usually red in color) in the 3-wire cable carries power from the ESC's BEC to the receiver. The signal wire (may be any of several colors) in the same cable carries throttle signals from the receiver to the ESC. The third wire (usually black or brown) in the 3-wire cable is the ground or common.
