I just noticed that it's twitching in the house due to interferance as someone suggested. I have a receiver pack charging about 3 feet away and as I was reaching over it to grab my soda, the servo's went nuts. So, I picked it up while it was still charging and the servo's went bisserk. Put it down, all is good. Lean toward it a little as if I was playing with the trigger on the remote (I had the remote sitting about a foot from the charging pack), and the twitch I had been seeing this morning came back. Lean away, and it's gone.
Sorry to drag this on and on guys. Thanks for the help. I'll see if the twitch shows up outside later today. It's supposed to get above 40 and be sunny... maybe I'll get to break something else!
