1. Props lower pitch. Possibly less noisy that the Bebop 2. 2. Possibly a little bit more movement (adjustment) in wind than the B2. Maybe I'm just more nervous. 3. Obviously photos and videos a lot better quality, as expected. 4. Auto record video on take off on the B2 is not the default on the P3. 5. Default ratio for photos is 4:3, which look narrow to me. 6. Gimbal up/down seemed the wrong way round to me but should get used to it. 7. The wealth of options/settings started me worrying I'd spent so long getting everything "just so" in pre-flight that I'd never take off! 8. Horizon wasn't quite level. I don't think I've done the IMU calibration. 9. With the P3 in my hand, doing the calibration or whatever, it's not immediately obvious which way it is. i.e. what is front and back. And also not obvious which are the "front LEDs" and which are the "aircraft status indicators". Just newbie thoughts really. Hopefully all will come good. Also noticed that the right stick sometimes didn't move the drone the way I was expecting. It's possible I imagined it but a couple of times it didn't seem to move relative to what I was pointing at. i.e. I'd push right and it would go backwards.
