Thanks!! All good advise. I did call JR and the guy said sound like a bad POT. I dunno.. thought about buying another one just to see what they tell me and sending this one in. Almost wonder if they all do this from defect.

One question on cumn thru's comment "Also make sure the hole that the servo sits in is not too tight". If it is not tight.. how do I make sure it stays in? I don't want to thread lock in case I need to adjust.. right?

Also... I never understood the servo mounting. The ucd manual says to drop some CA in the predrilled hole.. wait till completely dry.. then mount through the hole. That seems crazy to me... why not put it in while wet so it will stay.. what is the point of screwing into completely dry glue.

That will be the last of the newbie questions. Thanks everyone for the help.
