I have for sale a 68 foot piece of 8 conductor rotor cable. I am not sure of the size of the wire. It is 1/4" in diameter, and I have a 50 foot piece of it feeding a CD-45 rotor with no problem. It is used, and the jacket is dirty, but should work fine. I am asking $25 shipped and can take paypal/check/MO. 73 John AF5CC
