I apologize, I was mistaken. That controller cannot be used as a buddy box. I read this and misunderstood:

"The connectors on the InterLink Elite cord and included adapters make the InterLink Elite compatible with the trainer jack on most Futaba® and all JR®, Spektrum™ and Tower Hobbies® systems."

There is a forum where this question was asked (about using it as a buddy box) and the answer was no.

Again, my apologies.
