This is not my quad, it is a friend of mine's. He also has DJI Naza and was testing his FPV equipment when in the middle of the flight one of the bolts holding one boom came off and the boom moved close to the other boom on that side of the copter, and it almost became a tri-copter. It did stay in flight and quite stable. You could hear the two props hitting each other. He managed to bring it down close to the ground when one of the props unscrewed and came off (you can see it in the video), but the copter still stayed a float and then fell to the ground levelled. It was pretty awesome to see the Naza survive something like this.
