Ok, thanks guys. After reading the FAQ portion of the Futaba website and listening to what you all are saying, I think I will be ok. For one thing, the antenna does run thru the fuselage to the bottom of the tail section, right at ground level, diminishing the signal somewhat. It was the first time that I had range checked my plane with a buddy standing right next to it for him to see the chatter. Always before, I would just walk out and see that I still had control surface movement and could not see any chatter. It may have always been there and just never noticed it.

Oh well, thanks for the help.
