I just bought a phantom 2 with some random ebay gimbal for gopro. Unfortunately, there's no aux power in the legs and when i opened the shell, it doesnt seem to be there. Do i just solder the gimbals power directly on to where the battery is soldered onto the controlboard? Or is it possible to connect it to the flight controller? (I believe its the naza m v2?) Also i'm starting to look for possible fpv kits, which also need power. But maybe its better to have this on a seperate battery? And at last, is there anyway to remotely control the tilt of the gimbal?
