I was following in a chase car. I wanted push the flight distance and was not testing the extents of the transmitter capability. This was a Distance Fly using DJI Phantom 2 (non Vision) down Mount Charleston, Nevada. 10 miles. 3410 ft descent. Stock Battery! I hit an invisible wall at 10 miles because I forgot that I set 10 miles as distance limit in controller. battery was at 9% at the end. flight info collected via Flytrex core and overlay via Dashware
