Completely calm conditions this morning. Max distance was 19,335.7 feet at ~175 feet. 3.66 miles!!! Is that a world record for stock P4? Total flight distance was 38,839.1 feet with a total flight time of 14 minutes 41 seconds. Landed with 30% battery. Controller signal was full scale and HD downlink was -1 bar when I turned around. I believe I could have pushed it farther but didn't want to risk having to land in the water. Completely stock P4 and controller running auto channel mode. Any questions? Just ask! Photo of me was after I completed the flight.
