I just added two videos on youtube
First one is Belt-CP attempt to demonstrate vibration and the crappy camera didn't show it. It still got a good shot of the pitch problem.

Second video is the demonstration of vibration and that is on carpet, On concret, it is about 3 times worse and when i spin down it literally bends main rotors from its place and knocks the tail couple times on the ground.
