As for the servo draining your batteries. I wouldn't worry about it, all digital servos I have seen constantly are looking for center and it doesn't seem to hurt the battery life. I am happy digital servos are always looking for center, thats one of the reasons digital servo's are better then analog. It's make them more precise.
