New to the forum! I've been flying my FC40 for three months and want to upgrade with a gimbal and GoPro. I'm a beginner looking to launch a videography business within the next year or so. As a beginner, is the Zenmuse H3-2D that much better than the Walkera G-2D ($370 to $85) for the price? And will the video quality from the GoPro 4 Black ($500) with 1080p, 120fps be THAT much better than the GoPro 3 Silver ($300) with 1080p, 60fps? Money spent on those determines purchase time... Looking for input, thanks all!
