I received my h3-3d from b&h yesterday. Installed it with no issues... had a slight amount of jello at 2.7k 30fps. Removed adapter plate and installed white dampers under the plate, and used longer screws. Seems to have made a big difference. have only been able to fly in really high winds, but the video is very usable, unlike before with the h3-2d in high winds. I have noticed that the gimbal is not balanced left to right with the gopro.. when power is off, it rotates(falls) to the motor side. gimbal doesnt seem to get hot. Very pleased so far.
