Hi barkin_bob,

I would suggest sending this in to the Service Center to be checked.

I at first would have said that it might have only been interference on your channel at your field, but since you had the same problem at home later then it sounds like it may be your transmitter.

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
