NXT Paper Airplane Launcher

This paper airplane launcher was created from Lego NXT components. The plane flies between 25 and 35 feet. I had to compound the gears to obtain enough RPMs on the wheels to effectively launch the aircraft. The launcher also has a negative launch angle which may surprise some of you. This was done to account for the initial lift the wings supply at the time of launch. A level or positive launch angle would cause the plane to stall only a few feet after launch. This project was a lot of fun to build and
