RE: Servo going out?
While your waiting use the servo that's not borken to finish checking to see if it's the radio or not, plug it into the two different positions on the reciever and see if it works in both positions. The only thing that can actaully hinder using that servo is if it's a futaba style servo horn, I think they are smaller where the servo horn hooks on. Do you have a link for the servo. Ya might want to email the seller and ask him what style servo horn it is. But if he doesn't know, you can get a futaba servo horn cheap enough from your LHS, if not let me know I have futaba horns laying all over and I can send you one if it is a Futaba style horn.
