About this 3D model

This is my version of a tricopter yaw mechanism and motor mount. Everything is dimensioned for a 10mm shaft (mine is carbon fiber) and 35mm Turnigy G10 motors. On the yaw I used: 1x: set of linkage shafts (generic heli linkages): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=23116 1x: set of linkage balls (generic heli balls): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10169 2x: bearings (5mm ID X 11mm OD X 5mm W): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11520 1x: shaft (5mm D shaft): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=24822
