P4 Power Output for Video is only 0.598 Watts v. 0.746 Watts on Original P3P FCC ID SS3-WM3301512 by SZ DJI TECHNOLOGY CO., LTD for Phantom 4 The P4 feature set includes enhanced Lightbridge for greater video stabilty, but the video power output from the aircraft is still 20% less than the original W323 P3P. The P4 is, however, is still better than the last W323B version of the P3P, which at .520 Watts is a full 30% less than the original W323 P3P. Whether the "enhanced Lightbridge" can over come the 20% less power, and still maintain video stability at the same distance as the original P3P remains to be seen, but I am now less optimistic than I was before seeing the actual P4 video power output specs. The FCC site has been down since before March 1, and just came back online within the last 48 hours, finally revealing the P4 video power output. Currently, without a birdside video mod, the only P3P which supports stable video at low altitude from 3-5 miles is the original W323 P3P with the .746 watt power output.
