Hello I bought a used phantom 1 and it flies but with a mind of its own sometimes. How can I find out what firmware to download for this model P330D There are many downloads on the DJI website and I don't know which one I need like which Naza M v4 Firmware or whatever firmware this uses? Any ideas would help. Terry
This may help some https://www.droneflyers.com/2014/12/phantom-fc40-getting-started-guide-beginners/ The download should be on this page http://www.dji.com/product/phantom Naza-M Assistant.
