I used a massive reflecter to maintain connection with the drone. I wanted to do one last flight with my dji spark with a bad camera and bad gimbal but somehow I ended up breaking the world record for the distance!!! (Previous: 18 kms one way and back from yt-fly far and wide) and I got to 90 kilometers away from the homepoint! Unfortunately, I wasn't able to safely land on the island and the drone fell out of the air so there isn't any way to get it back!
