Hi - didn't see a thread similar to this... I've noticed as of late my camera getting stuck in various positions ... it has been stuck pointing down, at 45 degrees and most recently as far up as it can get. The dial on the control doesn't move it. Only when i physically move the camera (ie. i tilt it gently up or down) does it become "unstuck" and is able to move with the controller again. I'm wondering is it possible for it to be "dirty"? (i have flown it in some dusty areas)...and would some compressed air clean it out? Or is is something else? I think it's a mechanical issue on the camera because after i move it it has a full range of motion. Thoughts anyone?
