Someone with Futaba experience can answer both of those questions. I suggested that based on what I have.. Airtronics and Spektrum. I can do Airtronics to Airtronics, and Spektrum to Spektrum. I would imagine it's t he same for Futaba, but they have different types of jacks on the back of the radios that may require either adapters or a cable with the matching types of plugs on them. I'm sure someone will reply to your questions in short order.

I don't know about the RF interlink controller, though.
