I bought a Phantom 1 late last year, but unfortunately due to work and some other life events, I have not gotten to play with it since early this year. Now as I get back to working on it I realize that all the new accessories are designed to go on the Phantom 2 and finding ways to make them work on the Phantom 1 is getting more and more complicated (most notably I have ordered two zenmuse gimbals that say they will work on the Phantom 1, only to find that they do not include the necessary GCU). This makes me start to wonder if, before I start spending more money on my Phantom 1, if I should just sell my current setup and upgrade to a version 2 before I invest in all of the add ons. So I was looking for some advice from more experienced pilots. What are the benefits/capabilities that the phantom 2 has over the phantom 1?
