Does anyone know which anti drop pin kit I need for the gimbal on a Phantom 3 Pro? I'm assuming it's best to go with OEM DJI pins from what I've read? If not, is there a better aftermarket choice? All of the pins I'm seeing are listing a gimbal number, but I have no idea what the model # of this gimbal is. They also seem to look very long in the pictures, but it's hard to tell from a generic picture. Thanks guys.
