Don't get a new tail boom for that helicopter. Just use a piece of 2mm rod and cut it 5" long. You will have to file little flat spots on each end. They will be on the same side when you do, and not that deep. It keeps things from twisting. If you do it right, you won't have to glue it in. But, you can finish splitting the stock boom and get the wires out of it withouth breaking them. Then, cut, sand and install the solid 2mm carbon boom, wrap the wires around the boom, and it will be 10x as strong. And a LOT cheaper. lol
