I am currently in Goa, India, flying my Phantom 4 and it has been a spectacular couple of weeks of photography. I have a few questions and comments: 1) In the metadata for the photos, I see that the altitude is incorrectly recorded. The value recorded seems to be more than the actual altitude - there seems to be a normalizing constant added. (One surprise to me was, Adobe's ACR and Lightroom has the DJI Phantom 4 lens correction profile in their database.) 2) I notice that I get a weak transmission link signal warning when the Phantom is out around 1-1.5 Kms even if I have a direct line of sight. I wonder if I flattened out the antennas (to redirect its radiation pattern) as it got farther away it might make a difference. 3) Yesterday I had a close shave and I should have known about this. I decided to operate into critical battery territory and the bird landed right where it was. Fortunately, it was just 10 metres or so from me and on level ground. If it had happened on missions over water... 4) Finally - I did encounter some sudden rain (vide a thread I started some weeks ago) on a few missions and had to quickly bring home the copter. No issues whatsoever. I read that I could hold attitude in a critical battery situation but my controller just didn't seem to have any control over once it decided to plonk down. An example of a photo I took with the Phantom 4.
