RC Model Reviews

Does anyone out there know how to get a Turnigy 9X (flashed ER9X) working with a JR radio as the student when buddy boxed.
I have it working with an old WFly radio but it is a piece of junk and when I plug in the JR and go to the trainer menu I get nothing.
Please help
George.

I have found the answer and now have a working buddy cable.
If anyone is interested the design is here. You need to read it all to weed out the info.
