Hi all, I'm hopefully receiving my P2V+ today, and in reading the manual it's a little ambiguous about the Anti Drop Kit. Basically, these are the little posts between the gimbal and the gimbal mount. It says that 2 come installed out of the box. However, it doesn't really say whether or not the other two need to be installed. The package comes with 2 extra posts - are these supposed to be installed on the other two corners that don't have the Anti-drop kit installed? Or are the 2 pre-installed ones enough and the ones they give you in the bag are just spares? Please let me know what your thoughts are. Thanks! -Jeff.
