JUST BACK FROM PARIS. EVERYONE IS SHOUTING THERE!!
And the Eiffel tower has been fitted with a spotlight that shines across the whole city. Is that to spot any drones that are out at night?
So here is a little more on the video stream bitrates.
There is a neat little free PC app simply called Bitrate Viewer. If you drag a video file onto its window it does this.

So that is a typical example of P3A video rate connected to a EU iPad, sending 25 fps at a little over the reported 2kbps.
I thought this video looked fine live on my iPad mini, but with all you guys complaining about P3A video quality my delusions are now shattered.
Here is an excerpt from the video, showing the nasty artifacts that I had not noticed. Grass is always a great teller on bitrate.

DOWNLOAD to view the true quality, rather than just playing in the Dropbox viewer.
You might ask why that video is at 10Mbps, but that's because I compiled the clip in Vegas Pro and chose a higher rate to make sure it didn't interfere with the source quality.
Then I swapped for a P3P Camera.
Recording in the home I got the following bitrate when connected to the same EU iPad.
As I noted in another post, the frame rate changes to NTS 30fps and the bitrate increases to 5k.

Switching iPad location to US (and leaving at Auto bitrate) gives no change:

Selecting Custom and the minimum 4Mbps gives this:

So thats nowhere near 4Mbps. Much worse than P3A.
And finally setting to the Max of 10Mbps:

That is only half of what the slider says. Its just the same as Auto.
And this is with the controller within 1 metre of the static craft, so nothing to do with the distance or transmission quality.
I panned the gimbal wheel up and down during the recording to make sure there was lots of video data to transfer.
And there is some pixelation of the image even at "10Mbps", so it should have been trying its best to maximise the bitrate.
Maybe some P3P owner who is really in the US could recheck this, but is seems the only point in selecting Custom is to wind
down the bitrate to increase the transmission range.
And in theory, because is actually drops to a much lower bitrate than P3A, it ought to have a longer transmission range than the P3A. But a rubbish picture.
If I get a chance tomorrow I'll revisit the scene of my Dropbox video and capture the same shots at "4Mbps" and "10Mbps" to finish the story.
