Hi, I started up my Phantom yesterday and found I didn't hear the typical high pitch noise coming from the digital micro server controling the up down tilt of the camera. Then camera tilt no longer worked of course so I took apart the Phantom to verify the connections and reseat the cables. Still dead, I even went to the RC assistant software turning off and on the gimbal, still dead. I assume that DJI will replace this under warranty. Tho I was thinking I may like to use a higher end servo as a direct replacement swap of the stock servo. Has any done a direct replacement swap (not requiring mod to phantom) and any suggestions for where to get the replacement servo?
