The RC tech is really coming along. This thread had me checking out some of the videos on youtube. Type in FPV to get user made UAV RC planes. If you have ever wanted to fly but couldnt afford it this is a great alternative. Heres a few good videos to give you an idea. Both videos are styrofoam planes that cost less then a hundred dollars.

Heres an Eagletree OSD FPV system. Im thinking of this with an easystar and mounting the camera underneath instead of the first person view.
