toy

As a kid I always remember my Dad and I making up crazy airplane games to play on the checkerboard bedspread with our die cast planes. I was recently looking for something similar that my kids and I could enjoy, and I ran across "Crosshairs" by Stephen Tavener. My kids really enjoyed playing it...

Take a cheap plastic toy. Could be a plane, or a bird, or a spacecraft, etc. Cut it a little, add servos, motor and electronics, and see how it flies. Preferably one that can be obtained by most people, just in case it actually flies well! CHALLENGE :-)
