I just started using healthydrones.com and was very surprised with all the stats and information it pulls from the Phantom 4 log files(even pics somehow from the .txt log). It's a crazy amount of information I didn't realise was getting created and logged while flying and really helps me see where I can improve and spot any potential issues with the copter or batteries. I'm also a stats nerd so this is heaven for me But the really cool thing(at least for me) is the option to download a kml file for Google Earth and few the flight path in 3D over a map. Anyone else using the site? Is it useful over the long term? I've only got about 20 full flights under my belt on the P4(many more on other craft) but think more people should be using this as it really does tell you everything. I've no connection with the site by the way, just really impressed by it and think more people should be aware it exist(especially people new to the hobby). I signed up for the Gold option as its totally worth it for what you get, not sure the Pro would offer anything I need though.
