Johnny, yeah I was very surprised when Litchi crashed the first time with me. It has performed perfectly since November and I was even more surprised when it happened again. In fact, I think it may have crashed three times instead of two. The last time it happened, the drone was about 4,000 feet out and going further and I knew it would complete the mission and end up back near the takeoff point so I didn't worry. I simply tried to restart which it did ok but would not connect again. I finally got it going but the mission it was flying was not showing, just the map with the voice prompts. I kinda think it might be my iPad which is two years old and it has worked perfectly also. My wife has one just like mine and I might try hers a few flights to see if it crashes with hers. I recently updated to the latest version, 1.17.0 but I think the first crash was on the previous version. Anyway, if I figure it out or if someone posts a fix for this, I'll try it and come back here and note my results. I appreciate your information and happy flying.
