Homebrew UAV... So Cool!

Saw this article today:  http://www.pbs.org/kcet/wiredscience/video/163-diy_uavs.html

It's a wired video on PBS.  One of my hobbies is amatuer robotics.  Nothing serious but its fun geeky stuff to do with my young boys.  This is sort of the same thing but instead of little robot tanks or rovers like I make, these guys build robot controlled planes.  Coolness.  Just passing it on.  I use vex (http://www.vexlabs.com) and would like to get into the new lego mindstorms too.  Xbox sort of took over my hobby time lately (Damn you COD4!!) and all of my gear is packed away while we are having some work done on the house.  But this spring I plan to revive it and build some stuff.
