Brand new to the drone game, bought a Phantom 3 Pro on craigslist for $100, Drone seems be working, blinking yellow lights under 2 of the arms but other than that seemed to boot up fine. Anyways. I am trying to figure out how to get a replacement controller for the drone. The one it came was broken, (like the poor kids mother ran it over or atleast that's what he told me). I checked ebay and they seem to all be very pricey but some are listed for the $50 range. Will that work or what? I also was told that standard phantom 3's remotes won't work with the Pro? I tried searching this topic but couldnt really find anything. Thanks!
