I have been thinking about purchasing a 3DR Solo. The issue I have is can any other camera be used or is the GOPRO and the Sony the only camera that will work with the Solo? After you purchase a Solo and a GOPRO or Sony your almost at the price of a Phantom 3 Pro so I am torn between the two. The Solo is a great price right now, but when you add in a GOPRO or a Sony there is not much of a price difference. So if anyone has an answer please let me know. I have searched on line and cannot find a good answer.
