Hey guys, I just wanted to share this. I am part of a group of 4 student at California State University of Long Beach. We are currently working toward finishing up our senior design project, a single gas engine multi-rotor copter.
A RepRap 3D-Printer was a major factor in manufacturing our prototype. We manufactured a majority of our components utilizing one. Feel free to check it out and support!
