I noticed on the web many People complaining that the camera mount on there FC40 is a lil bit Janky and it don't always stay closed. and I noticed it dont take much to cause the camera to pop out of the holder as well as also pop lose from the shock mounts. SO i made to quick easy mods. First one was to thread some string threw the two rubber shock mounts on both the sides and tie each one in a loop. So that if it does come out at all you will not lose the cam holder and cam or lose any of the shock mounts. Second mod was to also make a secure tether for the camrea that is tied to the main arms of the camera mount so there is no way the camrea can go flying away in any kind of crash or mishap from the holders front latch not staying shut. I tried to see if there was any way to tie a string securely or any place I could eve put tape on it and hold it but not interfere with it fitting in the holder right. But could not find any good secure way to do it that I liked. Then I Noticed on the very top of the cam there is a T slot and a spring clip on the back. So found my self a tiny square washer that went to a screw in electrical tab on the back of different electronic devices tho if in a pinch I could of used a round washer also. But what I did was just thread a string threw the washer and tie a knot on it so it don't pull threw the washer. and then the washer slides in the t slot track and holds in place after it pops past the spring clip that keeps it from sliding out. and to test it while I still had a few feet of string attached and threw it hard like a yo yo a few times and its as secure as can be and as long as you are past the center point it will just slide to the end of the track were it can not come out. then I tied the lose end of sting on to holes by were the metal screw knob holds the holder on to the phantom and trimmed my ends and now I have a camera that can not come out on its own and get lost and is easy to attach and detach from its tether when I want it to. now I will never have to worry about losing my camera.
