Okay so I have an FC40, I know that it runs on a different frequency and therefore it's limited in some capacity (the stock camera is not very good). I tried a year ago or so to put a Sony Action camera on it, I even printed the plastic parts to make my own gimble from some parts I bought online. In the end it didn't work very well, I just don't have the time to get it working and frakly the plastic printed parts were lousy, and the Sony action Camera app was glitchy. So I want to get a used GoPro 3 (not sure what model), and a cheap gimble (that will work without much fuss). What type of Gopro 3 should I get and what gimble?
