These are the radio controlled witch and wizard planes designed by R/C enthusiast Otto Dieffenback. You can buy a kit of either one for $150, but all the electronics you have to provide yourself. I'm going to make enough of them to form my own Quidditch team. How many is that, anyways? "Seven -- three chasers, two beaters, a keeper and a seeker." I'm not even going to pretend I'm surprised that you knew that. What's Severus Snape's middle name? "Doesn't have one." Damn you know your shit!
Keep going for a closeup of each and two piss-poor quality videos.
Thanks to buddy Brian, who's going to build one with my face then fly it into the sun the way I've always dreamed of.
