My Advanced has 6 flight on her with no crashes or hand landings to speak of. Flew on Sunday by the lagoon and after landing I picked the drone up and heard a odd sound which I was not familiar with. It seems when I rotate the drone clockwise the gimbal makes a scratchy noise when the camera has reached its endpoint(left turn for camera). I thought it may sand trapped in it, cleaned it and still noise continues. Next I tried a gimbal calibration and sound still continues. Any advice?
