I've searched but I can't find anything. Has anyone done a Zenmuse H3-3D or 2D teardown? I dinged the roll servo (very bottom) and now the silver part rotates freely about 2mm. When I orient the silver part a certain way the gimbal functions as normal, but when I rotate it with resistance on the arm it puts the gimbal in a bad horizontal tilt. I see there are three screws on the arm and before I seriously break it I wondered if anyone has dissected one of these before. Maybe there is a tightening screw on in there or glue? My other two servos don't have any play in them. Thanks.
