Feiyu Tech AK4500 - Problems, jitter, and jumps. Custom Deadzone

Please read :
I bought the ak4500 2 weeks ago, updated to lasted firmware. I use custom setting on the deadzone. Speed=1, deadzone=100.
When paning and tilting at the same time, it always jump and jitter, and shake. The video is example of this problem.
