Sometimes when I yaw, like for a panoramic video, or just trying to yaw 10 or 20 degrees, my Phantom acts like a stubborn dog that doesn't want to turn it's head. Then all of a sudden BAM it yaws too fast. I input yaw control, and sometimes it yaws, and sometimes it doesn't. Sometimes it yaws fast and sometimes it yaws slow. I've used the cardboard with a hole cut out to ensure "constant and steady" input, but it still yaws slow and fast. FYI: It also has one heck of a time making it's mind up about where it wants to hover. One second it's fine where it is, and then it wanders over there and might even change altitude. Oh yea, then it'll wander somewhere else. I'm as confused as my bird. Here's a short video from today. I did not yaw left after about 4 seconds into the video, while it's still fading in.
