Anyone who missed this year’s inaugural MADExpo missed a fun show, and one of the best parts was the day 1 Keynote featuring Wintellect‘s Jeff Prosise.

Instead of regaling us with his expertise on Silverlight or other technologies, however, we decided to try something different, so Jeff spoke on his passion for his hobby of building and flying radio-controlled jet aircraft…as in with real jet engines. These babies fly at scale speeds of upwards of 2000 miles per hour, and can cost 10s of thousands of dollars to build. Jeff brought a couple of models to show off, including his 1/6th scale F-16 model (photo by David Giard):

Jeff also showed off some videos of both successful flights…and what happens when things don’t go so well…here are the videos, for those who missed out on the keynote (or who just want to see them again):
