What an evening!!! Flew both my drones tonight. Found some interesting findings. I'm out in the middle of nowhere with no wifi interference. I flew my P4 at a height of ~100 feet out over the water to a max distance of 15,638.9 feet. I was in P-Mode with Crash Avoidence off. Speed was 38 mph. I flew out until the Smart Return-To-Home told me to return. Signal never got low or cut out. I will push the P4 farther tomorrow morning and break this distance. When I returned I still had plenty of juice so I flew over neighborhood for a bit. The disappointing finding was I got 14 minutes and 53 seconds of flight time with 25% battery remaining. Total flight was 35,205.5 feet. I then launched my P3P Version A and did the same route. Max distance was 15,571.3 feet at 100 feet until I started getting a weak signal so I climbed to 187 feet and kept flying. I kept going a little ways even after Smart Return-To-Home and then turned around. Speed was 34-35 mph. I landed with 23% battery remaining and flight time was 13 minutes 18 seconds. Total flight distance was 31,436.8 feet. I will say when I flew Treasure Island in San Francisco the P4 cut out after 3,000 feet. The only thing I have done differently is I went into the DJI Go App and changed the channel from Auto to Manual and then back to Auto in between my flights from Treasure Island and the flight I did tonight. I have no idea if that makes a difference but maybe give it a shot? If you have any questions please let me know! I did find the P4 is solid in the air. If you point it in a direction and fly it doesn't move left or right a little like my P3P does.
