AirSTWing was initiated as an independent undergraduate research project to design, manufacture, and control a small quadrotor helicopter. It evolved into a senior design project headed by Roman Geykhman. I designed and manufactured the airframe for the helicopter. The project was a success overall, although we could not secure light enough rotors for untethered operation (the heavier rotors tended to bend the driveshafts). It was the first project that I worked on where weight minimization was a key objective.

Below is an image of the assembled helicopter. A few videos are posted on Roman's website:
