Hi guys I recently got a Phantom 3 Advanced after having serious range issues with the standard. I am happy with everything bar one niggling problem. One of the screws that the propellors screw into won't allow me to "spin" the prop on then tighten. It has to be turned round a lot to get it to tighten if that makes sense? Just wondering what anyone's advice is. Makes putting the prop on and off a lot longer !
