First time transporting my Phantom in a speedboat this weekend, I had it secured in the Nanuk 945 and the water wasn't too rough so it never got knocked around. When I started the Phantom the camera was just rolling up then down repeatedly but it stabilized after a few seconds. Then when I was hovering over water shooting video of my kids throwing rocks in the water it seemed to lose RPM briefly and lost a little altitude, I was maybe 30 feet over the water. And finally, at one point during a hover it pitched to the left quickly like it was going to fly in that direction, without any input from me, and then stabilized again. Just minor glitches I hope.
