Just wanted to get a feel for if anyone purchased an aftermarket gimbal clamp and/or camera protector? I'm curious to know how many people use them. The gimbal clamp that came with the Phantom 3 seems pretty weak....the camera still points down and is allowed to move. I'm not really sure when I'm even supposed to use it. I haven't transported it so to speak, but I do walk several hundred yards down to the park by my house to fly it..........is that ok that I'm carrying it around without the clamp on it?
