Phantom 2 non-vision is the bird I have to use. ZM gimbal h32d with gopro hero3+ black. I want to get an ipad so I can control the bird better and know all the information it can send me on screen. Is an Iosd mini with bluetooth enough? I also have the FPV hub and an avl58. If I go the ipad route, do I need the avl58 at all?
