RE: Hobbico CS 80 servo
You cut the red wire on the y harness that goes to the receiver. Then you plug another switch harness into one side of the y harness and a servo into the other The receiver has a swicth harness connected in the normal way . Now the receiver receives power from the regular battery pack 5 volts and the servo gets power from the pack that is plugged into the y harness 6 volts. The signal wire white comes from receiver to servo through the y harness like it normally does. The black wires are commo0n to both packs so everything is referenced to the same ground Thats it
