    Comparing specs between the P3 and P4 , on thewDJI site, I noticed that the Remote Control has been upgraded.

    P3 Transmitter Power (EIRP) P4 Transmitter Power ( EIRP )

    • FCC: 20 dBm FCC: 23 dBm
    • CE: 16 dBm CE: 17 dBm

    All of the models have had successive upgrades in power as they release. It is a good thing. :)

    Did the decrease in birdside power output result in anything negative ??
    I don't remember any posts of video range, decreasing, after the " C " version was released.
    If not, maybe the initial power output was above what was needed.

    It definitely did for me! However, I use the FPVLR v2 transmitter mod and fly up to 5 miles away. Control is fine. Video becomes unstable beyond 3 miles on the W323A bird, but is good to 5 miles on the W323 and W322 birds. I have no other explanation than the reduced video power output of 18% on the W323A bird, reduced by 30% on the W323B bird, which I haven't tried. I have have confirmed this performance described above on 3 of the W323 birds and 2 of the W323A birds, so it it is consistent between birds of the same iteration, and not just a one off anomaly.
