Hi b35853,

The TF-AM modules would not be legal for use today unless they have been narrow banded. As to where you might find one that is legal for use, you may try some online R/C swap meets.

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
Lead Futaba Customer Service and Programming Technician
