3DR IRIS+ AutoTune 1st Attempt

Please help us to find bad videos. Broken or unappropriated video content?
In this video we attempt to do an AutoTune to fine tune the PID settings in the IRIS+. At first it seems to work fine and flies great but then something happens that make the quad fly erratic and the gimbal starts shaking. When we got back home the default IRIS+ Parameters were loaded back into the quad from mission Planner. We'll have to try AutoTune again later as it was getting dark when we did this 1st attempt.
