Here's a small clue I left out that may be of importance in diagnosing the glitch; Upon closer observation I'm seeing that 2 of the 3 servos "PULSE", which means that exactly every 3 seconds the servos twitch at a steady uniform rate even when a glitch is not actively affecting the radio system. The Tx & Rx are new, but the servos are old, Could that be the problem ?, Reno, this could have something to do with your dirty servo pot theory! [&:] The glitching seems more active when the heli is on the ground and I walk up close to the heli, but during flight it dosn't seem to affect control of the heli, but I don't like any kind of glitch, it gives me the horrors. I'm just affraid the dam thing is gonna fly off and hurt someone!
