My Feedback: (2)

In a sailplane ([link=http://www.pbase.com/image/32331111]here[/link]), I have one aileron that randomly flutters and does not center. Then for no reason it goes away and centers great. While fluttering, putting pressure on the surface does nothing (does not flutter less, does not fluter more). Battery charge does not seem to effect it (flutters fresh charge, flutters after some hours of flying).

What should I be looking at, RX, servo extension or is this a classic symptom of a servo going bad ?

I can not reproduce it enough right now to swap out parts...

I would check the connections (unplug and re-install the connectors a few times) to be sure they are making good contact. If you can't find any connection issue, or any other problems such as loose hinges, bound up hinges, any excessive slop anywhere, etc, then my guess would be that the pots of the servos are worn and they need to come in for service.
