Testing new gimbal on the APM quadcopter

I have always had some problems with vibrations on my APM quadcopter. This is because my homebuilt gimbal was not sturdy enough. This is an attempt to make it better.

My new gimbal that I have built has a ball bearing on the opposite side of the tile motor, making the entire construction more sturdy. I have also built this one out of thicker plywood to prevent the wood from flexing as mush. As can be seen in the video, the results are pretty good, but there are some vibrations when a fly fast forward. Maybe this is because I still have the roll motor mounted the the fuselage using an old 3 mm plywood that can bend slightly. At the end of the video, there is a crash. While I rapier the quad I will try the make the gimbal even better.
