My P3P crashed into the dirt from about 5ft off the ground after hitting some low hanging foliage. The impact flipped the camera upside down. I removed the yaw arm and flipped it back over but when I turn it on, the gimbal doesn't go through initiation / calibration and the Go app shows "gimbal roll error". I couldn't find any physical damage on the outside so I took it apart. The attached image is of the roll and pitch circuit boards. I noticed that the same chip on both circuits looks like it has a small bubble on it. Is this normal or a sign that they need to be replaced?
