Ok, here's the latest. First, regarding the batteries; I am using two 4,000mah lipos with two regulators. The batteries were fully charged and load tested prior to beginning all of this yesterday.

Back to tonight, I replaced the Y harness and the extension from the Y harness to the receiver...still the same problem. At that point I removed the Y harness and hooked up one servo to a Powerbox and began centering the servo. At that time the one servo began fluttering again. I repeated with the second servo connected and it fluttered also. I think I have two servos with problems. I took the top off of the servos and to my untrained eyes the gears look ok. I guess I'll be sending them in to be checked out.

Any other thoughts???
