Any help would be greatly appreciated. Drone took a dive into the ground. Rear arm popped off and wont go back on. Any ideas what to do? If i go the route of DYI, do i ony need the rear axis? Everything works other than the arm hanging there. Im handy and videos online make it ook easy to take apart. Or if you knkw anyone in the Cincinnati OH area that can work on it, please let me know.
