Hi tweety_04_01,
While we are not sure of an interlink for the FMS simulator, you can use the 7C with the Great Planes Simulator, by means of their interlink with USB connector.
You may want to check their site at

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
