Propeller Plane

We had to design and modify a foam plane to become a rubber band propelled plane capable of dropping “seeds” for reforestation. 

In the default configuration, the plane kept drifting upwards, and then nosediving into the ground. We wanted to solve this problem by adding weight to the nose of the plane. We screwed in a screw into the nose of the plane, increasing the weight. It worked a little too well, though as it caused the plane to begin nose diving into the ground. In order to compensate for this extra weight,  we wedged a piece of folded paper between the fuselage and wing of the plane, increasing the angle of attack and increasing the lift. This combination of the weight from the screw and the paper to increase lift caused the plane to fly straight as we wanted it to.
