About this 3D model

This is a little single axis GoPro Tilt mount for a TBS Discovery. I often wanted to look down at things (not up sorry) The DDT500 is available but it sticks out so far and is expensive to get in AUS. Sorry I did not weigh the complete assembly before installing it, if i ever pull it apart again I will post up its weight. http://www.youtube.com/watch?v=N9jjsg9GIJQ http://www.rcgroups.com/forums/showthread.php?t=1967038
