The FP Cardinal-2

The FP Cardinal-2 is a low weight free flight aircraft that functions by flapping its wings like a bird. The material costs should not exceed one dollar. This aircraft can be built in a few hours and provides for a relaxing project and impressive flights. This aircraft functions with a rubber band that is winded before flight.

To build the aircraft, simply download and print both plans to fit to size on regular 8.5 by 11-inch printer paper. The front part of the flapping mechanism can be built from either balsa or can be 3D printed from the attached files.
