What did we do?

We picked out two planes with different wing shapes. The first plane had a flat-bottomed wing, which was curved on top but flat on the bottom. The second plane had a symmetrical wing, which was curved both on top and on the bottom. We decided to try three stunt maneuvers with each plane: an aileron roll, a snap roll and an inverted loop. Alex flew the planes and we both judged how well the plane completed the maneuvers, using a rating scale of zero to three. A rating of zero meant the plane couldn't complete the maneuver, while a three meant it completed the maneuver excellently. more...
