Ok Yunecc customer service if pretty fast. However I just got my Typhoon H from repair and after checking it. The Video on the ST16 in live view still shutters. But I starting to think that is normal for the H. I fly a P3 also and in its live view on my phone it is smooth. I finally tested the H with some tests to make sure the gimble was smooth. Look at video of me going left to right and right to left, then forward and back. The wind was barely blowing as you can see from the Tree to the right, It was dead calm where I was flying. You see nothing happens front and back. but when it goes left and the goes right it jolts for some reason. When I talk to Yunecc before I sent them another video of the H flying higher and because the wind was blowing a little that said, its because of the wind. Funny how the same thing happen when there is no wind. Also I tested for lose arms and look at this Video: Needless to say I am a little upset. They said it was checked.
