Knock On Wood, I haven't had problems so far, but I'm curious, so...

All systems Normal, except:
Radio Channel Quality -> POOR
I suppose this is nothing to worry about: P4P was sitting on the table, very near to the RC& iPad, and in the same room as the WiFi router… Do you agree?

I wonder why both accelerometers and gyroscopes were "Moving". The unit was standing still on the table, maybe just a faint vibration from the motors? Should I investigate further?



Third Picture IMG_011.jpg
Here the question is: Just one compass in use? The other would step in only if there was something wrong with the first one, or…?

I see this all the time with my p4.  It switches from good to poor.  It's probably a lot of 2.4ghz interference.  In my case it could be the 11 wifi I have throughout the house.

1) Nothing to worry about, as you say just some local interference.

2)Yes the IMU is detecting some movement.

3)Yes, yellow dot indicates the compass in use and redundant would become active if a fault developed in compass 1.

Thanks a lot! You know, after reading many posts about stuff not working properly I was still quite confident, but wondered if I was reading correctly my app screens or eventually missing something...

Being inside the warnings you are seeing don't mean anything. Too much interference their per se.
If you get those outside in an open field - then I would start wondering...

The hardest bit about flying the Phantom is building up the confidence that the system will generally do what it says on the tin. Best thing is just to fly in wide open areas and avoid the temptation to fly too close to things until you have a good understanding of what can go wrong.

Oh YES! Luckily I live in the Middle of Nowhere with just fields, pastures, gently rolling low hills and moors... some woods to fly over with a bit of care, but this is all. No tall buildings, just sparse farmhouses, no power lines (they all run underground), even scarce mobile phone coverage...  what I call paradise :-)

What a beautiful country and a nation able to afford underground power grid ... As for your OP, the only thing to be concerned is IMU reading. If the drone was sitting on the table doing nothing, than why it was detecting any movements? Not activated motors do not vibrate, vibrations from cooling fans should be not detectable ...

Any vibration can cause the IMU to move. it is extremely sensitive. Again this is normal!

Better ask then be sorry. We learn new things everyday. I command you for being careful and responsible pilot.

Thank you VERY much, Dronist.  I have a secret recipe: before buying the P4P I spent nearly a year studying first the danish rules,  watching all the DJI tutorials and a lot of Youtube videos (many I did not like at all, for careless flying -IMHO), then bought a little Hubsan with no camera and started learning how to fly it indoors and outdoors, then in January 2017 I bought the P4P and am learning to fly it -not hurrying it.  My first and foremost concern is  S A F E T Y.  My amusement isn't worth endangering somebody else...

I second that... I did the same thing few years ago . I spent a month flying in ATTI around my backyard after I watched couple of these flyaway videos and scared the hell out of me. Like you said there is nothing in the word worth endangering another human being!

Let's drink to that after we land and keep those videos coming.
