This is a Quadcopter Boom that I originally designed for my 3D Printable Carbon Quadcoper, but now i have made it more universal, so you too can print these out and make your own quick connectable quadcopter, Tricopter, Hexacopter, Or Octacopter frame!
.
With this set of parts you are able to not only to connect your boom to your copter physically on the go, but it will also connect electrically! There are three holes on the boom, and in the female portion of the quick connect, they are designed to accommodate 3 3.5mm bullet connectors. The female connectors are glued in the boom, while the male connectors are mounted into the female, main body quick connects!

If you make one please post pics!
