I've been lurking on the forum for a while and decided to pull the trigger and bought an H pro. Upgraded the firmware to the latest version (I know that's against some your recommendations), calibrated accelerometer, gimbal and compass and took it up for my first flight. Everything was fine until I brought it down to land and then it started the toilet bowl issue. Hadn't noticed it at all until I was down below 10 or 15 meters altitude. I was able to land it but it flopped over and killed the motors. The only "damage" I noticed was that two of the rubber mounts for the gimbal had popped out of the mounting bracket that slides onto the H. The other two mounts had a retaining pin in them and the stayed intact. Is that the way they are from the factory or did I lose two of the retaining pins? I also noticed that when I turn everything on and have GPS lock in angle mode that I have a solid purple LED on the H as I'm supposed to but I also get a white blink once every couple of seconds. I don't see any record of what that means. Anyone help me out with that? BTW...I really appreciate all the info people provide here on this forum.
