I took the UAV (3DR IRIS) for a flight yesterday, noticed several malfunctions on the gimbal. Here there is an edited video:

Notice the shaking and vibration starting and stopping at random times. Also when pointing the camera down it starts twitching strongly (2:59). The last flight I made with the gimbal was flawless. Only addition has been the gimbal adapter plate (printed from http://www.thingiverse.com/thing:274349), but it fits like a glove and I don't see how it can affect the function of the gimbal. I checked the cable connections twice, they are in the right spot. At 3:47 I do a video at home and you can hear the vibrations and see more details. Any advice will be appreciated.

Thank you for all your replies. After the update, the "Default Mode" went to "stick rate mode", so I changed it to "stick position mode" and now the channel 6 dial is working as usual. I noticed other changes:
- The Roll Setting Angle Limit went from 24 to -24 to 44 to -44 in v1.5. Also, the Tilt Setting Angle Limit went to some extreme numbers too, so I changed it to Max: 0 to Min: -90.
At least the vibrations have seemed to stop for now.
You may have already done this, but check the cable is not tight around the servo. I have had this happen to me before and found that when I flipped Iris on her back to put on GoPro you can rotate the housing too far and this winds the cable around the servo axis. This can happen when you fit the two small holding screws after taking GoPro on and off.
I kinda wish fitting GoPro was done on the other side so that you can download the vdos without having to take GP off every time.
Thank you, I was able to update to v1.5. The vibrations stopped. However, now the channel 6 dial to control the axis rotation works partially, it moves it to the next angle but won't bring it back. It is one issue after another.
