As we may have mentioned before, our design prompt was that Eric likes frisbee and we thought that it would be fun if we could modify it ever so slightly. We began with the idea that we wanted to raise and lower the frisbee, as well as turn it. We realized that this idea was just turning the frisbee into a ufo, rather than a frisbee. So we started again and this time David gave us a digital compass to work with. After several discussions, whether to use a propeller or a flap to decrease lift on one side of the frisbee, we agreed on the flap idea. And as you can see in the gif, that was our final product.
