I have never seen fuel tubing included with anything other than a nitro. Some will come with an areal mast, or antenna tube, but they don't need to be used with 2.4Ghz Tx's. I give mine to my cat.
Ahhh....so it must be antenna tubing. I have been reading and learned that it's recommended to use some form of rigid cover to protect the rx antenna. Mine seems to have become bent and the insulation is somewhat deteriorated.
What is typically used to replace antenna wires. Is this a simple solder job?
