Hi Adam,

Interference from either inside or outside the transmitter could cause the problems that you noted. It is just too hard to say what may have been at issue in your circumstance.

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
