That's great! Reminds me of elementary school when I was in "gifted and talented... " program. We did a similar experiment. Each kid had some ornate paper airplane, but my simple design won out.
My dad studied aviation in USSR between 1980-83 while my country was part of USSR. He also had amazing skills in aerodynamics and making paper planes. I guess USSR aviation schools were pretty good that times. Dad's school now http://kkluga.ru/
