I have a Phantom model P330. No modifications or additions have been made. I want to buy and install a Gimbal for my Real Estate related photos and video. The information on the web is very confusing as to what I need and should install. I was directed toward the Tarot 2D. However, I do not know what other controllers or internal components I need to install to make this or any gimbal work. I am looking to spend $350 max, and want to go from a stock Phantom and GoPro 3+. To a gimbaled version that can take crystal clear photos and video. What do I buy, and where can I get direction on how to install? Please make this simple for me. And thank you!
