Hi I got my Phantom2 wet almost exactly a year ago - had to replace two ESCs and motors, but the phantom flies fine now. Haven't flown it in almost a year, but the gopro and h3-2d (that came with the phantom) are damaged. I've purchased a new (used) gopro, but need to purchase a new gimbal. Heard about the h3-3d, but wondering if it's going to be "plug and play" into the phantom2 like the h3-2d was. I definitely need the single axis adjust like I used to be able to do with the lever on the back of the P2 remote. So my questions: - Is the H3-3D the same interface as the H3-2D? As in I wouldn't need anything else to connect it to the video transmitter, etc? - Notice they come with a "GCU"? my understanding is the P2 has this functionality built in so I don't need a GCU?
