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.
