Allows mounting a 1/8" square bar to the underside of an X525 or X666 quadcopter frame, projecting out. I use one to hold the receiver antenna and another to hold an orange ping pong ball for an orientation marker.
Designed to use M2 x 4 screws sold by Hobby King as set screws and to hold Plastruct .125" rod.
