will the futaba 6exas be a buddy box to the 6yg sky sport??? and what cable would i need ??

I just bought a new futaba buddy box from Tower and I am wondering if it will work with my 2 different planes that have futaba radios?

The buddy box is #T4YF
the radios are

1. #4vf radio system in a hobbico super star
2. #6yg skysport system in a hobbico hobbistar mkIII

I would like to be able to use it with both planes. I have the right cords for them also.

Thanx,
Ronnie-The Toolman

Here's the list of Futaba systems that are compatible with the trainer system:
