RE: servo noise
Did you see the finless videos on helifreak.com? The Align ball links have an "A" on one side, and that A faces out from the ball link. Perhaps a couple of them are too tight. Finless does a good job of explaining how to size them.
Also do a search, IIRC there were a few other people with the links hitting the canopy and there was a fix for it.
