Yesterday I was flying our P3S and noticed the camera pitch movement doesn't seem right. According to the user manual, it should be able to tilt down 90°. Once during flight, I achieved this, but it then seemed stuck and unwilling to return level. Throughout the remainder of the flight, I was able to tilt it down about 30° but couldn't get it to 90 again. Is this a known problem and is there a fix for it?
