$15 H3-2D GoPro insert for the H3-3D. It's a simple drop in install, and no more dealing with that flimsy usb micro ribbon cable nonsense. After having the ribbon cable break on me 3 times (I had to order the third from DJI) I was done with that garbage. This mod will pay for itself easily. Highly recommended for anyone using a H3-3D and getting fed up with the ribbon cable!
