Flew my P4 yesterday in a wide open , unobstructed area with full LOS and lost video and telemetry at 3100ft (altitude: 275ft). Had to hit RTH to gain control back. Also tested altitude range going straight up overhead. Video breaking up at 1100ft. Virtually no signal at 1640ft. Got about 16 minutes out of battery. Used sport mode for about 5 minutes of the flight. Battery drains rapidly in sport mode. Very disappointing that regular flight mode is restricted to about 20mph Max. The only way to get any speed is in sport mode. No medium ground. All video in sport mode has half the screen covered in prop wash. Video quality in 4K mode was poor at 24fps. Very jerky. When shooting in 2.7K at 60fps video quality was spectacular. Overall very disappointed . I had a P3A that was awesome in every way. Saw the P4 and decided to give my P3A to my friend as a wedding gift and get the P4. I'll be returning the P4 and buying another P3A. See no need for the 4K camera of the P3P. DJI blew it on this one. Maybe upgrades (P4-2nd Gen?) or P5? (Will be a while for that one) and I'll consider it if they make the proper adjustments. Until then, the best value available from DJI is the P3A which continues to drop in price.
