Two days before I finally flight over the mountain (https://youtu.be/15DgHrdZMgY), I made this first attempt in a cloudy day:
I almost lost it when my iPhone ran out of battery, and my disco was in a flight plan, 900m high, in the middle of the clouds. I completely panic, and began to press home button lots of times. 5 long minutes later as I still didn't see or hear it, I run home to pick my wife's iPhone and try to make a quick app installation and connection. When I run back to the field, the disco was there, planning in circles over the home point, next to a corn field. It reminded me that scene of Interestelar movie when they find the Indian drone. It was a really cool experience.
