I finished up the hardware and wrote a demo program. The demo program just stabilizes and auto-levels the aircraft, really just demonstrating what could be done with this project. The airplane gave me several challenges. I asked my fiance to paint the plane with acrylic paint, but that seemed to reduce the strength of the foamboard. Fortunately after adding LOTS of packing tape, it feels pretty sturdy.
Here is the demo video I made for the TI Intern Design Challenge. Sorry for the poor video quality.
