Yes, they will fit and; if you remove the xtl and battery from the slave, it is okay to use. The Hitec cord is wired slightly different from the Futaba cord and you can always use a Hitec cord with either a Futaba or Hitec but not visa versa or you risk causing both xmtrs to transmit. If you note, on the Hitec cord, one end is marked "master" and the other "slave".
