I want to make new videos, but in the past I had trouble getting the gimble angle correct. Either too much or too little. I have a gopro 4 using 1080 setting for video. If I have it at Zero, then I see the props at the top of the video. If I have too much and it is not "forward" enough. I have no FPV so I have to look at the camera on the Phantom 2 and guess. I can set the limit on my PC and wonder whats the best setting? I am guessing 10 to 15 degrees?
