Wow, what a fast reply!
I have tried unpluging different servos but haven't tried a new battery. The current battery has been cycled and appears to be in good shape but replacement is worth a try.
John, luckily I don't have an ECU to worry about since my settup is OS .91 with Dynamax.
I just range checked again with TX antenna collapsed and RX ant. out of fuselage and with certain orientations of the TX (not pointed at RX), I can get the servos to glitch at only 40 ft.
