Hi AIRPLANENUTS,

Before you do, if you are using long extensions, I would try checking them. Since this does not happen with all three models, it sounds as though there is a common denominator in the other two planes.
If you are using longer servo leads or extensions, you may want to try using a filter or heavy duty leads to see if this helps you out.

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
