Hello all, from Wisconsin here. Just stumbled across this site today. Got a Phantom 3 Pro in February from Amazon and returned it to get a Phantom 4 before my 30 days was up. Well over 100 miles of flight so far and I love it! Wanted a drone for quite some time and finally did. Now it just needs to stop raining like it has been lately. Have use both Litchi and Autopilot as well. Autopilot had an issue but through some beta feedback and the recent update it seems to be fixed. Haven't used Litchi on the P4 yet but did quite a bit on the P3, as it got me around the 22 MPH limit in follow mode. That was just too slow.
