In my recent crash I bent the rear arm stops on my Mavic so that the arms can move up a bit farther than they should. After doing a bit of research I decided to only replace the hinges rather than the whole arm. I've ordered two hinges on Ebay that should come in a few days so that should be good to go. Is there anything that I should know before trying to fix it? Any repair tips? I'm a bit nervous about soldering onto the main board.
