Tried 3 different locations before shipping it back. Looks like a mile is about it. This thing was built for closer range photography and a hi def signal back to the TX. The 7km touted distance is out of line. Flight times on the battery were roughly 24 min. Not 30 and I flew down to 17%. Id stay with the P4 and wait on the P5. This will need another generation to refine the hardware and hopefully loose this 2.4/ 5.8 nonsense in favor of the newer more robust Occusync.
