I'm trying to decide between the phantom 1 with a self installed tarot or zenmuse gimbal for my gopro black or the phantom 2 with a pre installed zenmuse gimbal. My dilemma comes down the the battery configuration and cost of additional batteries. I feel I would rather have the phantom 1 and purchase extra battery packs to achieve the same if not more flight time overall than if I were to purchase a single extra battery for the phantom 2 at a much higher cost. I don't mind a short flight, I just want a lot of overall flight time when I do fly. I'm also unsure if I like the whole proprietary battery pack thing. I also feel the connections on the phantom 2 are more susceptible to loss of contact from pilot error than the phantom 1 connections. Please correct me if I am wrong in my assumption. I would probably end up paying more for the phantom 1 with a gimbal installed by myself than I would for the phantom 2 with the gimbal installed from b and h photo. That is one of the main reasons for holding back on my purchase. I feel like I'm buying "the old model" for more money, but reliability and long term cost are also important to me. If I am missing critical info on why the phantom 2 is the way to go can someone please "school" me?
