Hello Folks,
I just posted this in a thread concerning an interface for FMS. It is a website that shows you how to make a Parallel port interface so you can use your radio to control FMS. It costs about $10 in parts from radio shack and it works great with my Futaba Super 8.
Hope this helps you guys and gals out. Glen
