Tim Shotts' Science Olympia Plane
 |
wingspan: 50cm chord: 12cm camber: 5% horizontal stab: 35cm chord: 12 cm camber: 5% - the pylons are offset from center 3/8" each motor stick: 3/16" x 3/16" x 9 7/8" boom: 1/8" x 1/8" x 8" prop: 6 3/4" guillows down thrust: 0* left thrust: 12* total mass: 7.6 gm w/o 2gm motor The wing and h-stab is built out of 1/16" square balsa. The best time I got in the silo was only 38 seconds, but the heater was on. The Silo is privately owned by a family in Rochester for indoor rock climbing. It has a diameter of about 35 feet and is 65 feet tall! It took a pretty tight-turning plane like this to fly in there and the inside wing was almost flattened by the banking of the plane. I'm 18 years old and a senior at Rochester High School in Illinois. I'm killing three flies with one slap" as my German teacher put it; It is for Science Olympiad, 4-H aerospace, and also I'm doing a science fair project with it. Sincerely, Tim Shotts |

This is the new tandem I built. It weighs 7.33gm without the landing gear that Science Olympiad requires. If you look closely, you can see the paper roll 7mm behind the front wing pylon. The center of gravity is 2cm ahead of the trailing edge. |
