Shawn makes a good point, if you want a really small plane there are a few interesting options such as those he suggested. Others I have seen are the flying witch, flying pizza, and flying bug. Scroll about halfway down this page for a few examples [link=http://www.towerhobbies.com/listings/cat-cat-a.html]http://www.towerhobbies.com/listings/cat-cat-a.html[/link]. I'm not sure how fast these things fly, but they are only about 20" in size and use all the smallest eletronics, so I don't imagine they could handle too much speed.
